Cabling Products: The Right Tools are Everything

The world of structured cabling materials and products is a vast and ever-changing. Because the industry of network cabling is so quick to revolutionize in technology and systems, newer products come onto the market all the time. While there are mainstays of equipment that can be trusted and used in many different situations, keeping up with the plethora of cabling elements is an important part of the structured cabling profession. Just the tip of the iceberg, these are two categories of cabling products used by network technicians.

SCP-L (Structured Cabling Products- Low Smoke Cables)

Low Smoke Zero Halogen (LSZH) refers to a material class used to describe cable coating or jacketing. Also known as ‘low smoke free of halogen’ or LSFH, this jacketing material is made of thermoplastic components that give of the least amount of smoke and halogen when in contact with strong heat or flame. While many network cables are coated with PVC, that plastic contains halogen which releases hydrogen chloride when exposed to heat, which is a poisonous gaseous material. Using low smoke cables keeps the level of toxic gases emitted from network cabling in the case of fire or flame. The same principles go into any other network hardware applied in high heat or fire-risk applications. These cables are used in particularly combustable situations, like under ventilated buildings or on planes or other vehicles. As networks are becoming more popular in unconventional situations, like commercial planes and public transit stations, these light, durable low smoke cables and hardware are being used more and more.

SCP-O (Structured Cabling Products- Optics)

Made of heated and stretched glass strands, optic cables are those which carry one or more optic fiber. These fibers are individually coated as to not bleed information into each other’s reflective information stream. These days, optic cables can hold up to about a thousand optic fibers and are responsible for many high definition deliveries of image and sound to televisions and computers worldwide. This optic sort of networking has it’s own specific system or connection and hardware to make the cabling. Fiber optics are in fact becoming incredibly popular, as they are in high demand for home entertainment and private business use. Especially in high information-traffic areas optic cables are very densely coated and made to be sturdy so that the signals do not have the opportunity to erode. Optic cables do, however have their own inherent flaws. Because the manufacturing process has yet to be perfected, imperfection exist in the fibers, which grow with time and use and degrade the optic capabilities. Professionals who deal with television network cabling know optic inside and out and use the tools constantly. Many network companies are even in the process of laying literal miles of optic cable so as to monopolize the information dead space to turn live when the market grow up in those areas.

Cabling materials are designed for such niche uses that understanding their tricks and intentions is very helpful in the structured cabling field. Some professionals will always be working in similar situation and will grow to understand one or another classification of structured cabling products more so than other, but a general understanding is truly best.

SCP-P Description

In the world of structured cabling, there is a wide smorgasbord of materials and equipment to be applied to the job. Different wiring, cabling, utility tools and hardware are used to solve all varieties of issues and complication in the designing building and maintenance of a cable network. These structured cabling products and materials are often classified or bulked together based on the sort of network they serve, and the kinds of construction codes they uphold. One example of these categories is Structured Cabling Products of the Plenum variety or, SCP-P.

Where is SCP-P Used?

Plenum cable is run in the plenum spaces of structures and buildings. This refers to the spaces in construction meant for the proper circulation of temperature control coming form heating and/or air conditioning systems. Because of the pressures and implications of these spaces, plenum cabling must meet very specific qualifications. Regulated by the National Fire Protection Association, SCP-P, and the plastics used to make them are constructed very carefully. They are tested extensively for fire safety under the NFPA code 90A which sets the rules and standards for building ventilation systems.

What is SCP-P?

Plenum cabling materials are coated or jacketed in a special fire-retardant case of polyvinyl chloride, (also known as PVC) or fluorinated ethylene polymer, (abbreviated FEP). These plastic compositions are compounded against flame and spark, and thus are the most safe to use in spaces where air and heat travel at great force. These sort of SCP-P is re-applied particularly in large buildings in which cable networks are installed as part of the infrastructure as opposed applied externally. This integration into the ventilation system follows suit of many construction practices of organizing similar systems in similar areas. In this case, information and power run over plenum cables, much like air and heat run through vents. This method is employed to help keep things tidy, as much of the cable ends up hidden in ceilings and walls.

SCP-P Prices

Though it depends on the exact sort of cable, most plenum cables are pretty affordable. You can purchase bulk plenum cable at a length of one thousand feet for under $200 dollars and the shelf-life of such cable is considerable. SCP-P are, however not necessary for every cabling job. Out-of-the-wall networks where heat and air exposure are not a factor do not require plenum products, and more basic casing around the cable will work just fine. Even with proper casing, plenum cables do where out and get degraded by cross frequencies and external environmental factors. As technology develops, these materials are being designed to be even more durable and long lasting. Because many industrial networks, like those in businesses and large office buildings use this method of SCP-P, the money for innovation is present and willing. Newly constructed houses and apartment buildings are also starting so apply plenum materials, so it is useful for structured cabling installer and technicians to keep these materials handy and to be well versed as to how they are used.

The Materials of Network Cabling

The saying “a man is only as good as his tools” is particularly true in the case of structured network cabling. The tools and materials of network cabling industry are numerous and varied. From metal wiring and plastic casing to cutting and crimping appliances, the toolbox of a cabling technician is very specific to the field. While many cabling installers and techs could construct many of these materials from scratch it is cheaper for them, and the customer if they purchase these components in bulk and measure what is needed per job. Network cabling materials and tools have been modernizing and changing design as technology and information improves. However, many of the basic building blocks remain the same.

Wiring
When individual cables degrade, network cabling professionals will often repair a small length of cable or cable connection internally with the smaller materials that make it. Twisted wire cables are still in effect within many networks. These cables are made of a series of bundled, twisted copper wires with metal mesh and/or plastic casing to help separate and organize the information frequencies that run along them. A good structured cabling professional will keep these individual parts with him at all times, particularly copper wiring of various metallurgic percentages. The plastic casing and the metal meshes used to repair cables are also good materials to hold onto in this profession.

Cabling
Bulk cables are the heartbeat of the material inventory of a cabling tech. Telephone, ethernet and various other network and electrical cables are the main structural equipment of information networks. Telephone Cat3 wire, network Cat4, Cat5, Cat5e, Cat6 and Cat6a are common cables used to build networks. These networks can require shorter lengths of under fifteen feet of cabling or longer amounts of hundreds of feet, depending on the job at hand. Newer cabling designs bundle multiple types of cable into one cord, and include coaxial cable, ethernet cable and other multi-media needs inside one casing. Another sort of cable that is being more frequently utilized is fiber-optic cabling. These stretched glass cables are used most frequently to deliver image and sound based information quickly and efficiently. More difficult to make and thus more expensive, those professionals who use

Hardware
The hardware used to install and maintain cable networks is perhaps the most varied material component of the job. From wall-mountings and soft patches to adapters and connecters, hardware is where much of the creative problem solving is done in the network cabling profession. Cable boxes, wireless routers and even actual computers and network devices are also considered as the hardware of the network. Different situations require much different pieces of hardware, and thus network cabling technicians must be prepares with the right particulars for each circumstance.

Tools
Unlike materials, many of the tools used in structured cabling have a longer life, and can be used for many different purposes. Cables often need to be cut in multiple layers or crimped to clip them off. Tools to install cables to walls or in the ground are also utilized. One of the most important, and less sustainable tools in the cabling tool box is several kinds of tape. Electrical tape is especially needed.

With so many types of materials involved in cabling it might be more accurate to say “a structured cabling tech is only as good as his knowledge of materials and his preparedness to use those materials and tools to get the job done.”

Network Cabling in Public Spaces

Traditionally, in the world of network cabling, structured cabling as a process is applied to a single building, unit, or room. These can be offices, homes, or private businesses. The intent is generally to provide internet access to those who use the space, or to create an internal computer network within the space to serve the purpose of connecting individuals and sharing information. There has been a recent movement toward cabling networks, particularly wireless networks accessible in public places.

Wireless Networks

This concept of public internet access has a fairly broad range of applications. Sometimes universities and colleges will support a campus wide wireless network, accessible to all those affiliated individuals who have the security code. Another example is malls and shopping centers who will have a strong wireless network meant to be shared with patrons and internal businesses. These examples are still in terms of ‘spot to spot’ wireless availability. This means that individuals must switch networks as they move from place to place, and usually must be affiliated financially with the networks they use. Municipal wireless networks or ‘Muni-fi’s are a bit different. They are city or region-wide wireless networks supported publicly by taxes paid. Sometimes, they span a single public outdoor space like a park or national protected land area, but more commonly they are a universal internet service and includes the whole city or town. This form of networking turns the entire area into a wireless access zone and provides businesses, homes, and citizens with consistent internet access in all locations. They are usually done in a mesh design in which signals are projected from poles and internally looped to hum up a strong signal. This takes the idea of citizens piggybacking on the wireless networks of cafes and libraries, and expands it into a sort of communal piggybacking.

Network Cabling Agencies

In New York City, Transit Wireless, along with the MTA (Metro Transit Authority) has been working to install wireless networks in the subways stations. The prototype began to function last year in several Chelsea stations on the west side of Manhattan. This year, the project has expanded to major hubs like Rockefeller center and Grand Central Station. These networks will allow not only cell phone reception for the millions of subway riders every year, but also free internet access during long subway train wait periods. This a public project, though it is greatly supported by several private agencies who would benefit from having patrons able to stay on their devices longer when underground. As the success of this installation expands, all subway stations will have networks, and eventually the possibility of individual trains having networks installed is high. Though many parks in NYC have wireless networks, the city at large has, as of yet, no Muni-fi to speak of, though it seems that that is the direction more metropolitan areas are heading.

Structured Cabling Industry

There is a pretty heated debate about the pros and cons of large public access wireless networks. The idea to is to bring the cost of wireless down for the community at large, and standardize it through the local government. This would be a great public service to those who cannot otherwise afford internet. It also provides a big boost in jobs to the structured cabling industry, keeping installers and technicians employed steadily with public funds. There are those who say muni-fi curtails the free trade of businesses who provide private wireless access as well has gives ‘big brother’ the availability to censor and control information moving in public and private spheres. However, as the debate continues, public networks continue to be constructed, and used by the population.

Private citizens, businesses and even large corporations and non-profits have taken a responsible interest in recent years in environmental and resource sustainability. As government funding and tax breaks encourage growth and innovation in the cabling industry, standards have been developed to ensure that sustainability is up-kept as the future unfolds. Structured cabling and network cabling in general is no exception to the run towards environmental care and energy sustainability.

Structured Cabling Field

The internationally recognized certification system for green building techniques is referred to as LEED. This acronym, standing for: Leadership in Energy and Environmental Design, provides an outside verification for buildings, businesses and communities to assure that they are planned and built with the aim of utilizing and sustainable practices and improving environmental efficiency. This includes energy usage, air emissions levels, water efficiency, indoor environmental elements and a general responsibility and leadership towards improving sustainability internally and throughout the community at large. While many building industries are included in the LEED ramifications, the structured cabling field is, for the most part, overlooked.

Structured Cabling Process and Equipment

Although LEED standards presently do not consider structured cabling processes and equipment, the problem solving towards better and more sustainability has already begun to develop within the cabling industry. The efficiency of certain cable designs maximize the amount of of information that can effectively gravel across it while minimizing the length of cord and the amount of general materials. Network cabling is also foundational to sustainability in that it creates a digital information storage and sharing that requires less paper to book or file and less storage resources in general. Actually, the more effective a cable networking system the overall more energy-saving the process. The fact that LEED qualifications pass over cable networking produces a specific flaw within the system. This hole in consideration means that many new building projects reroute funding in the budget from structured cabling to other issues, and thus the cabling ends up being second rate and in-efficient detracting from the overall sustainability of the structure or community.

Structures Cabling Industry

So, how can the structures cabling industry get the attention of the U.S. Green Building Council (USGBC) who designed LEED and prove that cabling is an important ally and aspect of environmental sustainability? First of all, lobbyist affiliated with the industry need to focus more on citing the sustainable benefits of structured cabling. A showcasing of developing technologies like fiber-optic cabling and twisted-wire advancements in public forums will also inform the population of the importance of sustainable advancement for philosophically and financially to the industry at large. Many of these new cabling technologies are seen only for their business, ease and speed capabilities; the light is rarely shown on how cabling can aid a business in it’s efforts towards sustainability. In the same vein, research and development efforts in the cable and network engineering field need more attention. Grants are available for this kind of research, to employ more sustainable tools that are made out of or from reusable and recyclable materials. While steps are being taken towards sustainability within structured cabling jobs, the real issue is publicizing those efforts and advancements more effectively.

Network Cabling Industry

Recent projections show that the network cabling industry is large and profitable and continues to grow worldwide. As the network cabling market increases over the next couple of years, a study from Bishop and Associates projects that the yearly revenue of the cabling industry will top eight billion dollars, and keep growing from their. There are several hubs or new fronts of the structured cabling game, areas where this growth is particularly felt. These new markets are good to keep in mind as technology is designed and structured cabling professionals look for new fronts to develop their businesses into.

South America Network Cabling

South America, particularly Brazil, Peru and the island nations are going through a shift. As governments stabilize and urban centers grow in size and population, these South American nations develop technology, manufacturing and corporate business, the demand fro computer networking and the easy stream of information increases. As much of this development is funded by or partnered with companies born in Europe or the U.S., there are usually preexisting relationships with structured cabling organizations. However, the job and education growth for local technicians and cablers is ever growing as more cabling is required, and opportunities present themselves to South American citizens who seek economic growth at home.

Network Cabling in Africa

A large continent, Africa is often overlooked as a new field for businesses because of the few truly devastated and war torn regions. Especially in West Africa, North Africa and the nation of South Africa, industry and economy are growing. While business ventures in Africa are still viewed as calculated risks, there are some endeavors that are more concrete and safer than others. And, as far as the riskier ventures are concerned, the profit to be made generally stands to be more because of that risk. These African regions are beginning to grow a middle class. As universities open and colonial infrastructures turn more to the hands of the local populace more people require cable networks both at work and in the home. Colonial wealth is still present, and larger homes and compounds will still provide a safe measure of cabling investment. As more africans leave the rural villages to more towards the urban opportunities of the larger cities, cabling is an industry that promises to grow, particularly along the coasts and in densely populated areas. Tourism is also getting to be a bigger industry in Africa and as foreigners come to visit they will expect the networking comforts of home and local organizations will seek to satisfy them.

India Network Cabling

A nation and a continent, India has many different regions that function socially and economically with great diversity. With a Huge population, and more than a handful of large cities, India is perhaps the biggest and more untapped market in the global economy. While economic and cultural diversity is large, the middle class is ever growing and with it, the demand for cabling to watch TV, access the internet and conduct businesses. Moving away from the internet cafe structure, more and more Indians desire the comforts of the internet within their own homes. There is also a bursting young generation of educated and qualified professionals, both the grow the industry of structured cabling, and to grow the industries that require it in the nation of India.

Cabling with Special Power Sources

In most situations in which information networking and structured cabling is utilized there is a fairly straightforward power source. Usually there is a hook up to a main public power line, privately paid for by the home or business owner. Because power of some sort is required to set up and run a cable network, circumstances in which electricity or power are more difficult or scant can make for tricky structured cabling work and require creative solutions from professionals.

Structured Cabling Work

One rather large organization that frequently deals with the problem solving of unusual power sources and cable networks is the many branches of the U.S. Military. Naval ships and submarines run electric currents from engines and generators. Air force planes and helicopters depend on various communication networks to navigate and locate allies and targets. Even on the ground troops in combat must deal with limited power resources when encamped to get their jobs done. Much of the energy needs for normal and special military operations are solved with the development of compact generators designed for high volume and complicated usage. However, many of the power sources that officers end of using still have their pitfalls. Many in-the-field power sources are unreliable, and can cause power to go in and out. Because of this, the military officers trained in and responsible for structured cabling must take precautions against energy surges and information loss from energy cut-outs. A large use of wireless networking helps eliminate the need for power and information to run through too many cables, and with the improvement in wireless technology range and strength, this is becoming a highly used solution to power issues.

The Military may be an example of one of the most crucial users of network cabling in odd power situations, but they are certainly not the only group that comes up against this challenge. Commercial ships and leisure vessels must also contend with generated power, as well as establishments in remote locations. Forest rangers in protected forests and lands, to which no municipal power lines run depend on network cabling for safety and emergency prevention. Ranchers, farmers and stable keepers rely a surprising amount on technologies that require networking and/or the internet and usually cannot fully depend on their power source to keep those networks running. Structured cabling professionals apply different means to problem-solve these situations. These solutions vary based on situation but surround surge protection, security and information saves within the software and hardware of the technology. The onset of energy-saving and energy use-minimizing cabling technologies is also important when energy is scant. The methods by which cables are circuited can create a stream of almost self-sustaining energy that can help to keep networks running on low power. In remote locations and third-world countries, battery-operated and rechargeable networking devices are utilized to make the most of electricity when it happens to be around. As more circumstances arise in which power an electricity is an issue in network cabling, more solutions will be invented and applied to keep information flowing smoothly.

Structured Cabling and Outdoor Locations

Specialized situations require specialized attention, particularly where structured cabling is concerned. While the processes of planning and installing a cable network are complicated enough inside usual circumstances like houses and commercial buildings, it is even more difficult in unconventional set ups. There is a whole other level of planning involved in the structured cabling of outdoor projects, rare venues and high demand projects. Structured cabling engineers and technicians apply a respectable amount of cunning and adaptability to meet the demands of these special structured cabling jobs.

Structured Cabling

One very particular example of a complicated cabling situation is outdoor events. Concert venues, outdoor theatrical productions, even drive-in movies require a strong cable network to do business. Outdoor stage events, and permanent park amphitheaters are also generally not small networks, and require a great deal of planning, not only for permanent network infrastructure but also wiring and cabling needed specifically for different happenings. As cabling technology advances, signal bleeding and frequency weakness are becoming easier to combat. In outdoor spaces, however, special consideration must be taken for keeping these cables dry from weather and secure from wind and storms. Temperature variance is another important factor to consider, and the placement and coating of cables must be able to keep the wiring form getting too hot or too cold. New inventions like thick gel tubing to surround cables and non-conductive metal tapes to secure connections are some of the many innovations that are already making outdoor structured cabling smoother and easier to maintain.

There are different ways to build networks, though many can be explained simplistically in the shape of a many-legged spider or a many-petalled flower. They move back through a central hub that helps to regulate signals and information and keep the flow of data clean. In outdoor venue cabling, this central hub is perhaps the most important point to secure and protect. In high volume situations, like concerts where many screens must play at once, generally with many tiny fiber optic panels within them, the signal must be strong. Often several different signals are run at once, carrying the same visual information, and serve as back ups in the case of anything interrupting the main frequency. In these situations where electric wiring and sound and lighting cabling are also present, there are particular practices to keep the overlap of circuitry from disturbing any single one of these systems.

There are cabling firms that specialize in the installation and maintenance of these outdoor cabling jobs. However, this work is often done by a large company that serves the whole region, for the mere fact that they usually own the majority of the pre-existing underground cables, and can run the strongest signals. In contrast, the organization on the network, and often its ability to project wirelessly is consulted on or designed by an outside network cabling worker who has experience overcoming the obstacles present. The more frequently these circumstances are considered in the education of structured cabling technicians and the design of structured cabling materials, the easier and more main stream structured cabling will be in outdoor situations.

Serpentine Technique

In the last ten to twenty years of cabling technology advances, cabling professionals have witnessed a good deal of change within their jobs. Particularly for structured cabling installation techs, skills and practices have gone through stages of development and modification. The standards of practice have been set forth by the ANSI/TIA/EIA-568-1991 Commercial Building Telecommunications Wiring Standard, which has been successfully updated several time since is was first established, keeping the regulations up to date. Many of the standards have to do with physical safety; keeping the technicians and civilians exposed to them safe from any possible danger. Some of this safety is day to day, while others consider more deeply the situations that arise in cases of emergency. Other standardizations help to insure the quality of the cabling: it’s ability to transfer information at speed, the preservation of signal strength and the efficient use of tools and materials towards the appropriate goals.

One example of how these practices have changed is the metamorphosis of the serpentine method. When running cabling for a network, large or small, it is important that the installer leave slack in the cable at specific points. This slack is usually not out in the open. Instead is is strategically placed behind walls or in technical closets. It is crucial to have for multiple reasons. First, if there is a change in the way the network is branched, excess will add for adjustments with as little splicing and building of cable as possible. Secondly, slack makes repairs easier and faster.

The question, as far as correct and preferred standards and practices are concerned, is how that extra cable is kept, stored and wired. There was a time when the cabling technology and information available drew the conclusion that looping and tying up this extra cable was the best way to store it. However as coaxial cable developed into multiple twisted pair cabling, encasing the cable signal with plastics and metals became less and less necessary. However, this new kind of cabling, while stronger and more efficient, has more troubles with physical signal interference. The looping method once used to store slack cable started to create problems for the new cable design. Looping the cord allowed for the creation of a self-made electrical current that can degrade and interrupt the flow of cable information. Therefore, a new storage method needed to be developed. The answer for coaxial cable, and for new fiberoptic technologies, is, in fact, the serpentine technique. This is a process in which cable is laid in many wide S shapes, thus utilizing less space to store more length of cable, while still keeping the cable from being pinched, or overlapping, which might interrupt the signals. Unlike a figure eight looping or a circular looping, the serpentine method maintained the structural integrity of the physical cabling, while maintaining the benefits of have slack cable for repairs and changes. This is one of many examples of how much and how quickly structured cabling technologies and practices are changing and developing side by side.

Electrician Training

One of the many little known facts about the electrician trade is the high degree of training required to get to the professional level. To become an electrician in the United States there are a great deal of requirements to meet. Depending on the state in which you train and seek to work, there are several stages of training possible. Generally, you begin as an apprentice. In some places you can only be taken on as an apprentice after several years of institution-based education. You then move to on the job training. This apprentice stage adds up to around eight thousand hours of work based learning. Much of the technical skills involved in electrics can only be gained and mastered through frequent practice.

To get an electrician job, you must prove yourself qualified. After thousands of hours of apprenticing and several years of education, electricians must take an extensive and state-mandated test to move on to the level of Journeyman Electrician. At all of these stages there is payed work. In fact the mechanism of how most electrical companies work is based n this system of raising electrical workers through the ranks. Apprentices learn all aspects of the trade from being exposed to it on the job when the results really do matter to the business and its clients. Once Journeyman status is acquired, there are usually two more years of on the job work and training to be done under a Master electrician. Pay rates at these levels are subject to location and work available. Electrical and Construction staffing agencies can help electricians to find stable and continuous work throughout any of these stages. Whether an electrician finds themselves doing work for a single employer, or contracted out on a job to job basis, electrical staffing companies can serve to minimize dry spells in income and in training.

After two to three years as a Journeyman electrician you can qualify to become a Master electrician. In most states there is a certification and government registration to be gained to get this status. In some places there is yet another round of testing. The time and rigor required to become a master electrician is equivalent to getting a graduate degree in an academic field. The government standards, while differing based on where you are, remain meticulous. For all the hoops jumped through to gain the education needed to be an electrician, the pay is also subject to circumstance. Twenty dollars an hour is a standard rate for Journeyman, and apprentices often make even less. While that pay is better than many jobs in a suffering economy, you must account for the cost of education and, in populated regions, the ever-increasing cost of living. While Master electrician jobs certainly are more lucrative, there are business costs to be accounted for. One thing that can be counted on, as far as electrician jobs are concerned, is the essential need for electrical work in American. Even in a suffering economy, buildings continue development and need to be wired by certified electricians. Jobs, to a certain extent, can be counted on in the electrical field, and continue to expand as power technologies evolve.

How Fast is Your Internet Really?

With internet access popping up in almost every home and business, is is important to stay informed and up to date about different connection types and internet speeds. It depends on how your internet is cabled, but most people today receive their connection either via a telecommunications phone line or a television or fiber optic line. Either way, many servers are run through a router that projects that internet connection across space to be picked up by wireless enabled devices. Depending on how it is run, projected and received, your internet will run at different speeds. Internet speed is measured both for uploading and downloading in Mbps is MBps. Mbps translates to megabits per second and refers to the number of units of data your connection can move over the course of one second of time. MBps refers to a larger unit of measure, megabytes, which are roughly eight times larger than megabits. When an internet service provider promises fast speeds they usually give MBps as a reference, but may use more misleading terms like ‘megs’ or ‘megas.’ This is why it is important to know what internet speed you really require for your usage and what speeds your company can truly provide.

Most people have a tendency to want was is newest and fastest. For many who use the internet, however, top speeds may not be always be so necessary. It is useful to note the differences, as many service providers charge more for higher speeds, and you may be paying for speed you don’t need. For homes and businesses where the internet is utilized for more basic tasks like dealing with email, reading content based sites and the downloading of images and music, less than 6Mbps are usually needed. With the rising popularity of entertainment sites like Netflix and Hulu, many homes and offices need to be able to stream video content with minimum delays in buffering. Most people find that they need a 6-10Mbps range to accomplish such tasks. To many these speeds are a normal range for internet usage. Beyond that, up to the 10-15Mbps range speeds are faster and download wait times shorter, though the difference is really only felt in locations where many multiple devices are downloading video or gaming content all at the same time.

While your internet bill may say you are paying for an 8Mbps, there are many reasons why you may not actually be receiving that as a running speed. If the structured cabling of your connection is week, improperly run or corroded by external interference, it can slow down your connection times. The greater strength and interconnectivity of the network, the more dependable connection and speeds will be, because they have stronger data streams to run along. Especially if your internet is run over phone wires, the bleeding of the signal can be greatly effected by outside sources. Sometimes speeds are slowed by the functionality of the wireless router and the reception of your various devices. You can test your speeds through various websites that offer the service, and sometimes at the site of your provider. Remember, most providers only guarantee a percentage of the speed you have purchased, so make sure to get what you, and make sure that you are in fact getting the speeds you payed for.

What is Cable Grounding and what are the benefits?

The Grounding or Earthing point of a cable or wire is usually the place at which the cable is connected to the earth and/or where the circuit completes itself and is measured. The concept of grounding came about along with the invention of circuitry, which in simplistic terms is the idea of electrical (or otherwise) currents running in a return loop, and requiring an eventual end to that cyclical journey. It was discovered that the ground was a good source to end, contain and measure those loops of power. Many types of cables are actually required, either by design or attention to safety, to be thoroughly grounded. The ground (or earth) is a relatively stable and dependable conductor of power, and a constant to measure the fluctuations of that power against. The main goal of cable grounding is to protect the signal from degradation and interference as well as protecting and materials or persons who come may come into contact with them.

Grounding a coaxial cable, (the kind you use for your TV or internet) can be achieved with a few basic tools and processes. If you are not a do-it-yourself kind of person, a reliable technician can be sought through your service provider. In most situations, the installation of your cabling system will have included an effective grounding process, but in some cases, understanding how grounding works enough to repair or install it on your own can be a good idea, especially in emergency situations.

You will need to acquire a grounding block appropriate to the sort of cable you are grounding. Most home improvement and hardware stores carry the varieties needed for such a task. There is also a basic connector that will ground the cable and its signal to the block. All of this takes place outside, at the place where the cable enters the building. The grounding wire (the connector) should get connected to the grounding block and then sent to the earth. Running the wire to the ground removes the static out of the actual block and ensures that the power current an effective outlet to run into. Grounding wires for television lines come in three basic sorts: aluminum, copper and copper-clad, all with varying thicknesses and sizes. It is important that you apply the correct kind of grounding wire for your system and circumstance. For many of these connections, a bit of silicone grease needs to be applied to the end of the wire before you screw it into the block.

The grounding wire’s job is to carry excess static and unwanted interference away from your system, sending it neutrally into the ground. Once the grounding wire and block are attached they can be mounted into a wall close to an entrance point of the building. Make sure that you ground your cable far away from where other cables are grounded. This can cause ground loops, where more than one current make contact with each other in the earth and send unwanted signal interference back into your system. Even if just to better comprehend the cabling system you have in your home or business, it is wise to check out the grounding system that may already be installed, and to understand how cable grounding serves to protect your information systems when installed or maintained in the future.

Fiber Optic Cables

In the world of cutting-edge and developmental cabling technologies, Fiber-Optics are at the top of the list. Most folks have heard some whisper of optical -fiber cabling and what can be used for, but the real specifics and complete rundown of the equipment tends to be more of and unknown. The general knowledge is usually that fiber-optic cable is a new and highly efficient means of transmitting information with high resolution. It is especially useful, therefore for television, internet and other visual media transmission. However, there are more questions surrounding what the cable actually is, how it is constructed and why its functionality is so good at moving data.

To understand optical fiber cabling one should probably begin with the tiny beauty of optical fibers. They are actually long, thin strands of glass that are made by heating up specialized glass to thousands of degrees and then stretching that glass out to lengths over sixty feet per second. During the fiber pulling process, a laser tool is used to measure and ensure that the strands are consistent in width and diameter and have no obvious flaws from beginning to end. It is the reflectiveness of these glass strands that allows them to move information over great distances. Once the strands are made they are exposed to ultraviolet waves and coated in plastic that allows them to act as internal mirrors refracting in each thread. Though these tiny strands are made of glass, they have great tensile strength and adaptability, setting them apart from other kinds of wires in their durability and usage abilities.

These optic fiber strands are the building blocks of fiber optic cables, which can hold one, two, or many individual fibers, depending upon their intended use. These fibers are placed in the center of such cables and encased in a plastic chute and a Kevlar layer to absorb shock, leaving the fibers space to bend and turn as they are run across tight spaces. Last, there is an external casing to protect and keep out environmental factors. This cable can then transmit signals with the assistance of an optic transmitter that adapts analog or electric information into light signals that fiber-optics are built for.
Fiber-optic cabling then runs these light signals to an optical receiver which returns the data to the form of its origin, making it readable on your computer or TV.

There are advantages to optical fiber cabling over other network cables, including its ability to transmit bigger batches of information over long distances with less interference and data loss. Signals run on fiber-optic cable are also less likely to be corroded by external radiation and frequency as copper cabling often is. There are also some disadvantages to fiber optics, mostly surrounding the fact that the materials are so specialized that it requires skill to maintain and repair them, and most information must go through a conversion process to run along the fibers, leaving space for missed or weak connections. Generally, however the advantages of Optical Fiber Cabling outweigh the issues, and as the technology is developed it is sure to become more and more commonly applied to network cabling.

Cat5, Cat5e, Cat6 Cables

If you’re new to the topic, the processes and materials of structured cabling can seem daunting and, of course, seeking the right professional is key. However, if you want some basic knowledge to inform decisions about the cabling in your business or home, it makes the most sense to start with the building blocks: cables. If you are installing a new LAN (local area network) or even just doing upkeep on an existing network, it will serve you to do a bit of cable research. As stated previously, a trusted cabling professional can help you make the best decision for your particular network, and while more modern and well made cables will cost more than the lesser, it will generally serve you to go with newer technologies that will be compatible with future innovations for the longest. Whether your network requires the transfer of information via voice, video and/or ethernet, it is beneficial to have a good grip on the advantages of several different cable types. The cables examined below have been standardized and differentiated by TIA/EIA-568, which has been responsible for the standardization of data cabling since the mid-1990s. These are the network cables most popularly in use today.

Cat5-(Category 5) This is a twisted pair cable designed to carry information in signal form from one end to the other. Because of the twisted pair design, the internal wires are able to move data with a limited amount of interruption or ‘noise’ and therefore usually do not need any shielding from external interference. This is the most commonly used Ethernet cable, but can also carry multi-line telephone and video streams.

Cat5e- (Category 5 enhanced) This cable superseded the cat5 cable in performance. Both are twisted pair cables, and both have the same bandwidth. The main difference between the two is that the cat 5e has tighter crosstalk settings. In layman’s terms, this means a decrease in the amount of signal bleed between cables, thus keeping information speed and clarity peak.

Cat6 – (Category 6) Hardware-compatible with the cat5 and cat5e cable, this cable has an even stricter approach to crosstalk and the reduction of external frequencies. [These differences in crosstalk reduction may seem small, but they can make a huge difference in your day-to-day network usage.]

Cat6a- (Category 6 augmented) As of 1998 this was the most advanced cabling recognized by TIA/EIA-568. This cable also marks the beginning in a shift in connecting physical hardware, requiring a hard-patch to make is compatible with an existing Cat cable network system. Performing at a differing frequency of alien noise reduction, a Cat6a cable exhibits around a fifty percent reduction in crosstalk over other Cat cables.

While what cable you end up using will be dependent upon the size and complexity of network you require, the clearer a stream of dependable information you can get, the better and faster you can get work accomplished. With the advice of s structured cabling technician and a bit of research, you can make an informed choice about structured cable.

Avoid Network Cabling Complications

Regardless of the sort of business you do, you are most likely heavily dependent on your Local Area Network to get your job done. When your network has issues or complications, it can put quite the wrench in your operations. Here are four practical ways to ensure that your network and it’s future are sound.

1. Plan Ahead

No matter what sort of technology your office is equipt with currently, it is important to stay up to date and informed about emerging technologies and how they might serve you. As your old systems need replacement it will serve you to choose the most recent equipment. Labor should be the costliest part of your network installation and while cheaper cables may seem like a good way to cut costs, they tend to wear out faster and require more expensive manpower to fix. Cable that is top-of-the-line is pricier, but will cause you fewer headaches. Using the right cable for the right purpose is also important. Twisted pair cabling can be more expensive than single cabling, and was once unnecessary for voice connections. Companies are often tempted to use two different cables, one for data and one for voice. However, as voice technologies advance, they are run more effectively on the same cable as data, and will be easier to organize and maintain if do so, and use Ethernet switch when needed.

2. Mind Where you Run Your Cables

Be sure you network cables are not run along the same route as your electrics. The magnetization of electrical wires can degrade the integrity of your data stream, and physical cables. This can disrupt or slow the transmission of information. If your cables must be near electric lines, make sure they are perpendicularly crossed instead. Also, be sure that there are no fixtures or devices near you network cabling that could introduce ‘noise’ into the data stream. This includes motors, fluorescent lighting, and anything that gives off a magnetic field. Remember as well that many cables have limitations on distance functionality. While you may be able to push at these limits a bit, it is important not to overdo it. Make sure you have the proper cable to run data the distance you need.

3. Follow Laws and Standards.

It will be beneficial to follow laws and standards. Those standards have been put in place for good reason and when you break them you risk not only inefficiency in your network, but danger to your information and staff. The structured EAI/TIA-568 standards are applied to optimize the performance of your network and to make it easy to maintain. Many areas also have codes to ensure the safety of installers and personnel and should not be ignored. They are particularly important in the case of emergencies for the work of first responders. You also risk fines and expenses upon inspection if you have not properly followed local legislation in these cases.

4. Hire the appropriate Labor.

Most network complications come from hiring the wrong person for the job. While in the past there were not as many data cabling specialists available and companies might turn to phone cabling workers or IT staff to solve network issues, that is no longer the case. To learn more about what makes a qualified structured cabling tech, seek out structured cabling staffing agencies who require a pedigree and guarantee the work of their staff. Once you have found a professional you can trust, take their advice. They, after all will be the ones maintaining you system.
