Why Your Company Should Avoid CCA Cabling – Part 2

30 Oct 2018

Cat6 Office Cabling Dallas TX Pittsburgh PAAs 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.

Why Your Company Should Avoid CCA Cabling – Part 1

22 Oct 2018

Cabling Network Cable Twisted PairsIf 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

cable,cabling,installation ,Washington DCDuring 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.

Office Cabling for Performance and Efficiency – Part 2

31 May 2018

Office Cabling   Network   Data CablingAs discussed in Part 1, office space has become very valuable and costly in many cities. Some companies will need to implement space optimization, and designing their structured cabling network is a good place to start. Part 2 will discuss Cabling System Performance and Densification of Networks.



Cabling System Performance


The TIA 568 standard sets the limit for runs of copper cable to 90 meters (295 feet) from floor distributor to workstations. Exceeding this length will cause greater signal losses or insertion loss and delay limitations due to the Ethernet protocol, which can decrease the performance of the network.


An expansive floor size with a proper number of floor distributors will oftentimes result in cables longer than 90 meters and greater insertion losses. Moreover, short cable runs are affected by crosstalk and return loss.


Due to the increasing implementation of 2.5, 5G, and 10G Ethernet, along with the newest high performance WAP (wireless access points), it is crucial to install a category cable, such as CAT6A, capable of handling higher bandwidth demands in the future.



Densification of Networks


Horizontal distributor optimization inside the equipment room will result in increased floor space and improved network densification. The optimization of floor distributors can improve the usage of LAN Ethernet switches, minimizing intra-building backbone runs. Implementing optimized distributor placement will ease the management of the network and increase reliability.


The use of fiber and copper panels with higher port density should also be considered by network managers. One way to gauge design efficiency is to calculate the number of ports per unit of rack space. This assessment will result in the optimization of rack space, decreasing racks and maximizing floor space.


Using wall-mounted panels for terminating cables and easing their management should also be considered. This will also ensure the prioritization of LAN equipment and fiber panels for rack space. This method suits companies who desire the convergence of building applications and IP networks.

Fiber Optic Advantages


Cabling, network cabling, cable InstallationsAs discussed in Part 1, fiber cables provide a number of advantages that make them superior to copper cables. This includes longer distance effectiveness, greater bandwidth capacity, resistance to electromagnetic interference, safer usage, and stronger security. Part 2 will discuss how fiber optic functions, its two main types, and fiber networks.



How Fiber Optic Cables Function


Fiber optic cables transmit data through the generation of pulses of light by light-emitting diodes (LEDs) or lasers. A fiber optic cable is composed of either a single strand or several strands of glass, each measuring slightly thicker than human hair.


The core is located in every filament’s center, and it is where light travels. Covered by cladding made of a glass layer, the core is able to reflect light inward, preventing signal loss and letting light travel through the cable’s bends.



Two Main Types


There are two main types of fiber optic cabling, single mode and multimode. Using extremely thin glass filaments, single mode fiber optic uses a laser to generate pulses of light, while multimode utilizes LEDs.


By utilizing the technique of Wave Division Multiplexing (WDM), single mode fiber networks raise the volume of data traffic transmitted over a filament. Combining light at various wavelengths is termed multiplexing, while separating them is called de-multiplexing. Thus, several streams of communication can be transmitted on a single pulse of light.



Fiber Networks


The installation of the majority of fiber cabling is intended to support long distance connections between national and international geographical locations. However, a number of internet service providers (ISPs) have made investments in the expansion of fiber to provide direct access to homes in suburban neighborhoods. These are termed "last mile" installations.


FTTH (Fiber to the Home) services, such as Google Fiber and Verizon FIOS, are becoming more common. They can provide homes with gigabit (1 Gbps) internet speeds. Direct fiber cabling runs directly from a main office to a single client, providing maximum bandwidth. In contrast, shared fiber cabling is ultimately distributed among several groups of users who are in close proximity.

Fiber Optic Cabling for Your Business – Part 1

8 Oct 2017

Technology,Network Cabling, cablesThe 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.

Important Considerations for Structured Cabling

13 Sep 2017

 cables,structured cabling, Network CablingAn infrastructure for enterprise communications, structured cabling is a system of hardware and cables designed for flexibility and future capability. Complying with the Electronic Industry Alliance/Telecommunications Industry Association (EIA/TIA), conventional structured cabling meets the organization’s standards internationally. The following are three important aspects of structured cabling that every organization should consider.



Savings


Over time, IT infrastructure has become more condensed and more sophisticated, and the importance of structured cabling has grown. Structured cabling eases a company’s expansion via a design that allows the adoption of additional hardware and software. As it has consistent network architecture, structured cabling allows the simplification of maintenance and repair, decreasing costs of upkeep. A study by the International Engineering Consortium discovered that standardizing cabling components and reducing cable delivery methods decreased startup construction outlay by almost a third. Moreover, expenses for network maintenance are lowered 40%.



Trends


Structured cabling is gradually making the transition from copper cabling to fiber optic because companies desire greater speed and better air circulation for the reduction of cooling costs. Lighter and narrower cables allow an overhead system of cabling to be installed instead of raised-floor cabling. The installation and management of cabling is made easier by less cumbersome cables, and so this trend will grow over time.



Planning


Sound planning is crucial for the success of IT projects. The future number of users, their locations, and required bandwidth must be diligently considered. How PoE (Power over Ethernet) will provide power to devices via must be studied. As Wi-Fi use grows, the number of wireless access points must be determined by every enterprise. Where will cables be located inside and outside the premises? Will the structured cabling be able to cope with moves and changes within the premises? Scalability and flexibility are both important, and so the locations of furniture and server racks must be carefully planned with respect to cabling. IT staff should also understand that different types of cable have limitations as to the length of their respective runs. Finally, there may be government regulations for structured cabling that require compliance.

Data Cabling,Structured Cabling,Washington DC

Setting Up a Campus Network

23 Jul 2017

Data Cabling,Structured Cabling,Washington DCAcademic 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 Organizations that Set Cabling Standards

27 May 2017

Data Cabling,Network Cabling,Atlanta GAThe 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.
