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.

Academic institutions can garner all the benefits of the Internet age by integrating information and communications technology (ICT) with their teaching and learning environments. ICT is an extension of the term for information technology (IT), emphasizing the unification of telecommunications, computers, software, storage, and audio-visual components within a network.

The quality of education can be significantly improved through the sharing of skills, resources, content, and faculty development. IT content and resources should be available to both faculty and students throughout the campus. To this end, academic institutions must establish a network in each of their campuses, achieving the same speed of data transfer at each building.

Typically, a campus network is comprised of several local area networks (LANs) that are interconnected inside a specific geographical area. Networking components, such as switches, routers, and firewalls, and transmission media, such as copper cable and optical fiber, are utilized for interconnection and communication between connected devices.

Campus Network Topology

For academic institutions like colleges or universities, a campus area network should be interconnected to various types of buildings, including administrative, academic, library, student center, hostel, guest house, sports facility, conference, technology, training, and laboratory.

A campus network will be interconnected via high-speed Ethernet cabling over optical fiber of up to 10GB capability. For the efficient processing of data and information traffic using distribution, access and core segments, tiered hierarchal architecture is utilized.

Every building, block, center, and residential complex will be connected by high-speed optical fiber cable. Moreover, every node within a building will be connected with UTP copper cable that supports gigabit speed.

The conference rooms, teaching halls, and common areas inside each campus will be Wi-Fi enabled through the deployment of 802.11 based wireless access points with central authentication, permitting secure network access via laptops, tablets, smartphones, and other Wi-Fi enabled devices.

Internet services, along with common applications, will also be installed at key locations, such as library study halls, allowing students, faculty, and staff easy access via desktop computers and laptops around the clock.

The TIA (Telecommunications Industry Association) and the ISO (International Organization for Standardization) are the primary organizations that oversee the development of structured cabling standards for the industry. Committees formed by the IEEE (Institute of Electrical and Electronics Engineers) provide assistance through testing and setting performance specifications for various standards.

Compliance with standards ensures the functioning of systems at specified levels, backward compatibility, and a greater selection of equipment will exist. General global recognition of standards permit utilizing equipment sourced from various countries inside computer systems. Requirements for the components of optical and copper cabling including cables, assemblies, connectors, cabling spacing and pathways, administration, field testing, and installation are standardized to make worldwide acceptance possible.

Technicians in North America typically use TIA standards, while the rest of the world uses ISO standards. Examples of organizations that set regional and national standards organizations are CENELEC (European Committee for Electrotechnical Standardization), CSA (Canadian Standards Association) and JSA (Japanese Standards Association). Their standards are generally compatible with TIA and ISO.

Different terminology used by TIA and ISO Associations sometimes cause confusion because they refer to the same item. For example, what the TIA terms as Cat5e is what ISO terms to be Class D. However, adherence to standards set by TIA and ISO ensure system cabling requirements are properly implemented in the categories below.

• Insertion Loss – Decrease of signal strength down the transmission line.


• Return Loss – Measurement of signal reflections on the cable.


• NEXT – Near End Crosstalk Loss due to signal coupling.


• Propagation Delay / Delay Skew – Elapsed time for signal to reach other end of cable or the delay between signal arrival at far end on slowest and fastest cable pairs.


• ACR – Difference between insertion loss and NEXT.


• ELFEXT – Identical to NEXT, but for cabling system’s far end.


• PSANEXT / PSAACRF – Power sum alien crosstalk at near end / Power sum alien crosstalk at far end.

Due to ever-increasing data rates, the efforts of the standards organizations are assuming greater importance in terms of ensuring proper system design.
