Why Your Company Should Avoid CCA Cabling – Part 1

22 Oct 2018

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.

Office Cabling for Performance and Efficiency – Part 2

31 May 2018

Stu Kushner

Office Cabling Network Data Cabling As 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.

Stu Kushner

Structured Cabling,Network Cabling ,Data Cabling Washington D.C As discussed in Part 2, there are considerable cost savings from the deployment of zone cabling systems. Part 3 will continue discussing the basics and benefits of zone cabling.

Additional Zone Cabling Benefits

Additional IP devices for audio & video, BAS, digital signage, voice, data security, digital signage, WAPs (wireless application protocols), etc. can be integrated easily into the current structured cabling system through ZE (zone enclosure) connections.

Extra ports within the ZE facilitate fast MACs (moves, adds, and changes) of current service configurations.

For easing installation and decreasing labor costs, tested trunking and factory pre-terminated cables can be utilized.

Increased efficiency of pathway utilization will be realized for the entire facility space.

Structured cabling system deployment will be speedier and cause less disruption.

Smart & Green Building Designs

Perfect for smart and green building designs, zone cabling systems can reduce labor expenses and waste of cabling materials. Centralized connections inside ZEs achieve greater efficiency for the routing of pathways. LEED credits provided by the United States Green Building Council (USGBC) can be maximized. In addition, cable sharing can support several low-speed and low pair count applications functioning on a single 4-pair cabling system. This achieves greater efficiency in cable and pathway utilization.

Summary

Modern workspaces are becoming more social and flexible, and they are increasingly reconfigured and updated with greater frequency.

Zone cabling systems allows flexibility in work spaces, facilitating faster and less disruptive moves, adds, and changes than traditional cabling systems.

Zone cabling allows for greater efficiency in the use of pathways and materials, which is required for smart and green building designs.

CAT 6A shielded cabling is recommended in zone cabling designs to achieve maximum performance.

Shielded CAT 6A zone cabling designs result in greater performance, better support of remote powering applications, and ZE termination flexibility at practically no additional cost in comparison to CAT 6A UTP designs.

Regardless of size, zone cabling installations planned with 25% spare port availability will considerably decrease client disruption and allow the facility owner to recover the expense for extra ports inside two to five years or after achieving the threshold for ROI.

Network Cabling,Cat6 Cable New York City As mentioned in Part 1, zone cabling designs provide benefits in materials savings, decreased installation times, and easier MACs (moves, adds, and changes). Part 2 will continue discussing the basics and benefits of zone cabling.

Designs

Experts recommend CAT 5e and 6 UTP (unshielded twisted pair) zone cabling topology with a connecting block system within the ZE (zone enclosure). This configuration will render unnecessary the stocking of factory pre-terminated and tested interconnect cords for connections in the ZE, simplifying cable management through the elimination of cable slack.

Please note that CAT 6A UTP media is not recommended for zone cabling due to reasons involving performance and flexibility. UTP cabling is vulnerable to crosstalk in particular installation scenarios. In addition, it is not the best media for supporting remote power applications with loads of 30W or more. Because CAT 6A UTP zone deployment is dependent on modular connections inside the ZE, connections provided by pre-terminated and tested interconnect cords need to be available for rapidly enabling MACs. Affordable shielded zone cabling solutions are recommended to address these situations.

Cost Savings

Even though more CAPEX (capital expenditure) will be necessary for a zone cabling installation, assessing total costs should also account for OPEX (operating expenditure). The performance of MACs is classified as OPEX, and studies by Siemon found there are hundreds of dollars in savings from each move, addition, or change when using a zone cabling design versus a traditional cabling design. Their study also discovered a tipping point when ROI begins accruing from utilizing a zone cabling design.

IT (information technology) needs for many organizations evolve constantly, which requires being able to quickly reconfigure floor space. An improved capability of supporting MACs will allow owners of facilities to achieve considerable ROI benefits from deploying zone cabling systems in a two to five year period. According to Siemon, the combined costs of CAPEX and OPEX for zone cabling designs will be invariably less than traditional cabling designs

8 Network Cabling Mistakes to Avoid – Part 1

9 Nov 2017

Stu Kushner

Cat5 Cat6 Network Cabling,Washington DC Improperly installed twisted pair cabling can result in poor network performance, maintenance issues, and concealed expenses. The following article discusses eight network cabling errors to avoid. To get the best results for your cabling project, make sure to consult with a company that is experienced and provides excellent service.

Mistake No. 1: No Future Planning

If your company is moving to a new office space and new cabling will be required, it would be wise to avoid outdated technology and install equipment that will meet both your current and future needs. Labor costs will likely be the costliest aspect of the project. Although high-quality cable will not be cheap, it will be well worth the investment for your firm’s network requirements the next several years.

Mistake No. 2: Poor Cable Management

Implementing rack-based and ladder rack cable management will certainly raise the outlay for a project. However, sound cable management will ease maintenance and decrease downtime. You should be aware that cabling tasks do not end after installation. Additional cables will probably be needed, and configurations may be revised. Use a standard system for labeling and color coding cables for faster and easier identification. Doing so will speed tasks like repair, reconfiguration, and replacement.

Mistake No. 3: Parallel with Electrical Wiring

Generated by low voltage, the magnetic field conducted by data UTP (unshielded twisted pair) cables is an important feature for the conveyance of data. However, when UTP cables run parallel to electric wiring, there will be a disruption of its magnetic field. This results in garbled and noisy communication. Sometimes transmissions completely fail from point to point. Another negative effect is the extreme slowing of transmission.

Mistake No. 4: Nearby Devices and Fixtures

Noise can be introduced onto data cabling by more than just electrical wires. Fluorescent lighting, motors, and similar items that shed electrical or magnetic interference will wreak havoc on your cabling infrastructure as well. Make sure that in your planning, you leave a data cable pathway that avoids these kinds of hazards.

Part 2 will discuss four more network cabling errors to avoid.

The 5 Most Common Structured Cabling Errors – Part 2

28 Oct 2017

Stu Kushner

Structured Cabling,Washington DC New York City As mentioned in Part 1, structured cabling systems are so standardized that good practices should merely entail following ISO/IEC, CENELEC or Telecommunications Industry Association (TIA) documentation. Part 2 will discuss three more common errors of structured cabling.

Error No. 3

Failing to properly test a structured cabling system after installation is the third error. Structured cabling represents a large commitment of capital expenditure and will typically have the same length of service life as the facility itself. Ensuring that the entire system is installed to specification and the data is at the capacity and speed expected is crucial. Finally, properly testing the cabling system is required to validate the warranty.

Cables installed during the early period of construction may have been subsequently damaged by other workers performing their roles later during the project. Moreover, new cables that appear fine on the exterior may actually be faulty because of damage underneath the coating as a result of being mishandled. All cables require calibrated testing.

Error No. 4

Using unqualified technicians for installation is the fourth error. Scrimping on the quality of workers installing cabling is an unwise way to save money. Problems will eventually be revealed over time. Prior to committing to a service contract with a structured cabling service, review their credentials and confirm their references. Have conversations with previous customers whose project is similar in scope to yours. Working with a reputable structured cabling firm will help make sure your project will be successful for the long term.

Error No. 5

Letting structured cabling patch panels become disorganized is the fifth error. It will harm both the performance and reliability of a company’s IT systems. As time passes, the patch panel or switch ports may be damaged, causing intermittent problems that are very hard to pinpoint. The use of proper cable management hardware for supporting patch cables is good practice. Complying with the specified patching standards required for a particular structured cabling system will result in a sound and reliable network.
