Why Your Company Should Avoid CCA Cabling – Part 2

30 Oct 2018

Cat6 Office Cabling Dallas TX Pittsburgh PA As discussed in Part 1, companies that have a limited budget for network infrastructure may end up buying copper clad aluminum (CCA) cabling to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets. Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Shortened Cable Runs

As lengthier CCA cable runs approach the 100-meter maximum, there will be a decrease of signal strength in comparison to solid copper CAT5e cabling. Reduced signal strength can result in data loss because increased packets of data must be retransmitted.

Unsuitable for Power Over Ethernet (PoE)

Since CCA wires have a higher DC resistance (about 55% greater) than solid copper, its conductors may need to be 60% larger than solid copper to compensate. Without resistance compensation, the drop in voltage will be greater for any channel length.

Longer cable runs of 65 meters or more will surpass TIA’s channel DCR requirements, limiting the available voltage for the device. In addition, higher resistance will result in a faster buildup of radiant heat, which may damage the device.

How to Identify CCA Cabling

CCA wire is also much more brittle than solid copper wire. Identifying CCA is easy because all you need to find is the silver color of the tip of the conductor. Another way is scraping away the thin copper surface of the conductor to reveal the aluminum.

CCA cables also weigh much less than solid copper cables. Go to the CCCA website for the CableCheck™ mobile app (http://cccassoc.org/news/free-apps/), which provides the approximate correct box weights to help detect CCA conductors being used to fraudulently substitute for solid copper conductors.

When a CCA cable is labeled as a Category 5e, 6 or 6A cable or CMP or CMR rated, it is counterfeit cable. It will also be non-compliant with industry performance standards and will pose a hazard by being unable to pass UL fire safety testing.

Cabling Network Cable Twisted Pairs If your company has a limited budget for network infrastructure, your team may be tempted to find numerous way to economize. Unfortunately, this may lead to buying CCA cabling in order to save money. Although marketed as a sufficient substitute for solid copper cabling, CCA cables are far from being the right answer for trimming budgets.

Definition of CCA

CCA stands for copper coated aluminum. A CCA cable’s core is an inner aluminum conductor that is coated with copper. As a result, it weighs considerably less than solid copper cables.

A CCA cable can be made at a significantly reduced cost than the solid copper version. This gives a manufacturer an increased profit margin and a significant competitive edge over those companies who continue making solid copper cable.

CCA cables may look similar and are advertised to function just like standard CAT5e or CAT6 cabling, but they have serious flaws that could result in network issues, business continuity problems, and safety hazards as discussed below.

Non-Compliant

CCA twisted pair cables are non-compliant with UL and TIA standards, which require solid or stranded copper conductors. The National Electrical Code (NEC) also does not provide CCA cabling a valid safety listing. Thus, CCA cables cannot be installed legally if the facility requires CM, CMG, CMP, CMR, or CMX rated cables.

Inflexible

As CCA conductors are brittle and easily break, just transferring a faceplate or patch panel can result in failures. CCA wires have low tensile strength, and they are known to break from shearing or pulling, which can happen during packaging or delivery. Moreover, CCA cables have a very limited bend radius.

Oxidation

Aluminum begins oxidizing very rapidly when it is exposed to air. This oxidation and the resulting corrosion may lead to failed terminations inside the network infrastructure, resulting in connectivity issues.

Part 2 will continue discussing CCA cabling related issues and counterfeit copper cabling.

Why Cable Pros Select Fiber Optic Over Copper Cabling

29 Aug 2018

Stu Kushner

cable,cabling,installation ,Washington DC During your consideration of the kind of cable that should be selected for your IT network, several factors come into play. One of the decisions you will need to make is whether to use copper or fiber optic cabling.

Copper certainly has plusses. It is already installed in numerous sites and is less costly for connecting network components. Although fiber optic cabling has a higher price tag, it has key advantages that make it more attractive than copper for creating structured cabling infrastructure.

The following are five reasons why most cable professionals select fiber optic over copper cabling.

Durability

Fiber optic cables have longer service lives than copper, decreasing maintenance costs and downtimes from replacements. Although fiber optic wires are made of glass, copper wires are more susceptible to being damaged.

Fiber Optic is Faster

When evaluating the transmission of copper wire to that of fiber optic, the contest can be simplified to the comparison of the speed of electrons to the speed of photons. Although C transmissions do not move at the speed of light, they are still extremely fast by moving just 31% slower than the speed of light!

Low Attenuation

Over long distances, fiber optic cables will undergo much less signal loss than copper. This quality is termed “low attenuation.” Due to attenuation, copper cables are capable of transmitting information up to a maximum of 9,328 ft, when it then loses power. In contrast, fiber optic cables are capable of transmissions up to 24.8 miles.

Resistance to EMI (Electromagnetic Interference)

If improperly installed, copper cables will generate electromagnetic currents that result in EMI inside nearby wires, which can cause serious problems throughout a network. On the other hand, fiber optic cables are not conductors of electricity.

Safer

Fiber optic cabling is safer because it won’t be a fire hazard. The reason is no electrical current travels through fiber optic cables.

Technology,Network Cabling, cables The widespread use of fiber optic cabling stems from 1950s research. These studies eventually made transmitting visible images via glass filament possible. This new technology was eventually used for viewing instruments and remote illumination for surgery. Subsequently, George Hockham and Charles Kao successfully achieved data transmission through glass fiber in 1966.

Fiber optic cabling is composed of glass fiber filaments housed within insulated casing, and these cables were designed for long distance, large capacity, and high performance data networking and telecommunications. In comparison to wired cables, fiber optic has high-bandwidth capability and is capable of data transmission over longer distances. Due to these properties, fiber optic cabling is used for a great portion of telephone, internet, and cable television systems around the world.

Fiber Optic Advantages

Fiber cables provide a number of advantages that make them superior to copper cabling. Due to properties of high bandwidth and low-loss, fiber optic cabling can be utilized over much greater distances than copper cables. Fiber optic cables can run up to 2 kilometers for data networks without repeaters. This is because light can travel much further on fiber cable and still retain its strength.

Fiber optic cables have greater capacity. Through the use of multiplexers, a single fiber optic cable can have the same network bandwidth as several hundred copper cables. It is now standard for fiber cables to be rated at 10 Gbps, 40 Gbps, and 100 Gbps.

Although it has special shielding as protection against electromagnetic interference, copper network cable is still susceptible when numerous cables are close to each other. This is in contrast to the physical properties of the glass used in fiber optic cables.

Fiber optic is also safer to use than copper in volatile spaces, where sparks can lead to disaster. It also has the upper hand in terms of security because tapping fiber cable to steal data transmission is very difficult.

Part 2 will discuss how fiber optic functions, its two main types, and fiber networks.

Data Cabling,Network Cabling, Washington DC Cabling utilized for network infrastructure is a crucial aspect of networking, and it has grown in importance as new technologies are introduced, including virtualization, wireless access points, blade servers, network storage devices, etc.

Although wireless technology has greatly advanced, most of the existing computer networks are still using cables as the media for transferring data. Each standardized type of network cable is utilized for a specific purpose as discussed below.

Coaxial Cables

Patented in 1880 (yes, that long ago!), coaxial cable is most familiar as the cable that connects TV sets to their antennas and also as the standard for 10 Mbps Ethernet, which was common in the 1980s and early 1990s. During this time, networks utilized two coaxial cable types, thicknet, the 10BASE5 standard, or thinnet, the 10BASE2 standard. Composed of an inner copper wire surrounded by insulation and shielding, the stiff quality of these cables made them difficult to install and maintain.

Twisted Pair Cables

During the 1970s, Ethernet was developed at Xerox, which began collaborating with Intel and DEC for its standardization. The initial specifications, titled the Ethernet Blue Book or DIX from their three company initials, was published in 1980.

In the 1990s, twisted pair cables became the primary cabling standard of Ethernet, beginning at 10 Mbps with Category 3 or Cat3, which was followed by 100 Mbps Cat5 and Cat5e and up to 10 Gbps (10GBASE-T). Ranging up to eight wires wound together in pairs, this type of cabling is intended to minimize electromagnetic interference.

Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) are the two chief twisted pair cable types standardized by the industry. Due to lower manufacturing costs, modern Ethernet cables utilize UTP wiring. STP cabling is used by other types of networks like Fiber Distributed Data Interface (FDDI). Clearly the most common network cable type globally, UTP cable is utilized for both networking and for the traditional telephone (UTP-CAT1) cabling.

UTP-CAT5e or Cat5e has become the most common UTP cable as it replaced coaxial cable, which was unable to cope with the increasing demand for networks that were faster and more reliable.

Part 2 will cover Fiber Optics, USB Cables, and Crossover Cables.

Basics of Riser Cables

6 Mar 2015

Stu Kushner

Structured Cabling,Network Cabling Data Cabling Riser cables were designed for non-plenum vertical applications like between the floors of multi-story buildings. They are also described as backbone cables. These cables serve as the main conduit of a distribution system for data, video or voice. It originates from the point where communications go in through a particular edifice. This cable comprises part of the structure backbone. Other components of this facility are the cable corridors, telecommunications cabinets, equipment rooms, correlated hardware, and support facilities. This cable variety must be fire resistant in accordance with electrical codes. Nonetheless, specifications are not as stringent compared to plenum cables.

Understand its Uses

Riser cables may be used for different forms of data communications which also includes CCTV video access. It is ideal as well for voice communications. One major concern is that requirements vary for each service. Hat is why planning can sometimes be quite complicated. Building managers are often pressed to predict their requirements given limited time and expertise. Quite often they will recommend creating split riser systems for multiple applications which follow parallel routes through the corridors, closets, and equipment areas.

How do you select the medium?

Perhaps, the primary concern is to stay within budget. You can expect system designers to resort to trade-offs in delivering a broad assortment of services within the backbone system. Other factors that may influence their design are the following:

Provide an adaptable medium in relation to supported services

Identify the necessary useful life span of backbone cabling

Consider the technical needs of users

Standards are on hand to serve as a guide in the design of riser cable systems. There are appropriate benchmarks for optical and copper cable backbone structures. Some of the backbone cable categories include:

Copper-shielded and unshielded twisted-pair or UTP cables

Coaxial and twin axial cabling configurations

Single mode and micron multimode optical fibers

Physical locations supporting riser cables take into consideration the telecommunications service entrances and adjacent equipment rooms containing the main cross-connect. This can extend to the telecommunications closets that serve a particular location, intermediate cross-connects that serve a number of telecommunications closets, or horizontal cross-connects for a remote telecommunications closet or just one level of the building. The telecommunications cabinet is the point of interaction between backbone systems and parallel (same floor) wiring.

Riser cable systems in multiple-story buildings need to pass through equivalent closets making use of connecting conduits between the floors. Said design provides each floor access to the backbone and allows circuits to be distributed to all levels. The conduit and sleeves should go higher than the floor level by at least an inch and fitted with fire-stopping material. These should also adhere to electrical codes. The riser or backbone cable system essentially acts as the core of telecommunications infrastructure.

Benefits of Copper Cabling Solutions

4 May 2014

Stu Kushner

cable testing, Network Cabling ,Data Cabling ,cat6-cabling The conventional process of copper cabling has been used for several years and is still preferred by many network cable providers and end-users. Companies like Progressive Office Cabling offer a complete range of cabling solutions in Cat5, Cat5e, Cat6a and Cat6, providing clients with high-quality cable as well as connectivity components. Progressive Office Cabling makes use of highly effective cable management systems and well-trained technicians for installation jobs. It also employs a web-based online project management system to guarantee proper implementation and monitoring of any project.

How Does Copper Cabling Work?

Installation technicians have to follow specific policies and standards, particularly when it comes to building structure concerns. There are several steps to follow with regard to installation. First, the cable should have the appropriate covering or insulation, which is normally made of PVC, Plenum, Ultra-Violet, or mold-resistant varieties. The cable is cut according to the needed length, and outer covers are removed before connectors are attached. Use the appropriate stripping tools for this purpose. Cables should be mounted as orderly as possible.

There are instances when installers have to use ladder trays and J-hooks, which are made for network cabling, or shoot nails into concrete ceilings using a tool that literally propels nails like bullets into the concrete surfaces. Network cables must be installed away from electric power lines, fluorescent lamps and industrial machines; the risk of electrical coupling can increase dependent on proximity and voltage factors.

Different Benefits

Copper cabling has multiple benefits and is the most effective conductor out there. Copper cables are flexible, which is especially advantageous if you are using electrical wires. It is necessary to bend the wire during installation, so you need something durable that will not easily break after a lot of twisting. Copper does not easily melt, so even if a sudden surge of current or overload takes place, there is no risk of burning or melting. At the same time, copper is not difficult to work on. The majority of electricians opt for copper wires because they can be stripped easily or pulled through rigid spots.

With regard to structured copper cabling, there is the Power over Ethernet benefit. This means that it is possible to run power through devices such as Wireless Access Points, surveillance cameras, and power phones. There is an emergency power supply that continues to power mission-critical devices even if electrical power conks out. Copper cabling supports modern technologies and facilitates the convergence of different applications. Hence, it is important that copper cabling is optimized for your requirements. That is why you should make sure to get the services only of experienced and trustworthy providers in the industry. Choose the provider that ensures customer satisfaction and warranty after installation.
