Cabling Network Cable Twisted Pairs

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.

Basics and Benefits of Zone Cabling – Part 2

14 Dec 2017

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

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.

Security Aspects of Structured Cabling – Part 1

11 Jul 2017
 

structured Cable Management/ BlogCabling system designed for the purpose of security have hardly changed the last decade and a half. Delivering video images and access control data to a control room utilizing standard transmission technology is basic and familiar. What has recently changed is the transition to IP-based security products and the rapid increase in business applications, resulting in end-users expecting a greater video, audio, and data integration. All of these items require delivery over one standardized structured cable system.


As opposed to traditional video and access control systems, voice and data communications cabling systems have had numerous transformations. Functioning on structured cable systems, data networks have shifted from the pioneering 1980s proprietary cabling to standards-based cabling using optical fiber and balanced twisted pair. This has resulted in greater transmission speeds and significantly increased network bandwidth. These two elements allow a security installer to achieve integration that is demanded by clients for CCTV, access control, and other applications. Through the adoption of standardized structured cabling, installers will be able to access new streams of revenue and provide tangible benefits to users by unifying all of their systems within one cabling infrastructure.


This change in the utilization and deployment of structured cabling systems was recognized by ANSI/TIA-862-B “Structured Cabling Infrastructure Standard for Intelligent Building Systems”, which was developed by the TIA TR-42.1 Commercial Building Cabling Subcommittee and released February 2016. This standard features the requirements of several standard and developing systems that are able to use the existing cabling of buildings. It also includes Distributed Building Services that do not utilize a building’s infrastructure cabling because of application, connector, historic, and topographic limitations.


A company’s network infrastructure is crucial in the distribution of information using electronic media, including CCTV, access control, data, and voice. Functioning over a structured cabling system, this distribution network is developed for the perpetual flow of data, featuring redundancy at the heart.  Installed with centralized topology, this enabled the most facile sharing of resources achievable, along with the greatest flexibility and expandability possible.

Challenges and Planning of a Structured Cable System – Part 3

5 Jul 2017

 structured Cabling, Network Cabling, Washington DCAs previously discussed, the transition to IP-based security products and the rapid increase in business applications has resulted in end-users expecting greater video, audio, and data integration. These items require delivery over a standardized structured cable system. The following are the benefits offered by structured cabling for security systems. Part 3 will cover the Challenges and Planning of a Structured Cabling System.



Challenges


Typically, customers exploring the security market are advised that the only method for deploying a new access control system or an IP video surveillance system is through the removal of all current coaxial or UTP cable and then the installation of an entirely new Cat 5/6 structured cabling network.


Another method is much less disruptive and cheaper. It uses existing cable and employs an IP transmission system that is a hybrid. There are numerous hybrid transmission systems available that enable installers to make good use of extended Ethernet and PoE power distances through existing cable.



Planning


An effective, structured cabling system supports all the communication needs of a company with the integrated flexibility that enables users to link to CCTV cameras, VoIP telephones, access control points, and data devices. Planning a security system upgrade will include several crucial considerations as summarized below.




  • Applications: What will the system accommodate now as far as data, video, voice, and multimedia applications? What emerging technologies will be adapted in the future?

  • Service Lifetime: The service lifetime of a structured cabling system should be 15 to 20 years because it will be the spine of an organization’s communications network.

  • Compatibility: The applications that will function on the structured cabling system for the foreseeable future should be compatible with it.

  • Bandwidth: As bandwidth demand will usually increase because of business growth, a company must consider present and future demand.

  • Users: For the 15 to 20 year service lifetime of the structured cabling system, the estimated number of users during this period should determine the capacity required.

  • Modifications: Fiber-optic technologies are being developed rapidly, and the design of a structured cabling network should include flexibility in order to accommodate modifications and additional users.

Introduction to Network Cabling – Part 1

12 Jun 2017

 Data Cabling,Network Cabling, Washington DCCabling 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.

Category 5e Cabling Becoming Obsolete

4 Apr 2017

cable,Data Cabling ,Cat5e, Cat6/6a CablingIt is inevitable that applications requiring speeds greater than 100 Mbps and 1000 Mbps will increase. The growing use of wireless devices, high resolution images, HD video streaming, surveillance, and multimedia are straining the capacity of Category 5e infrastructure, and there will come a point when it will be unable to cope.


Although it is capable of handling 1000 Mbps speeds at 100 MHz, the upgrading of Category 5e cabling will be necessary in the near future in order to support new applications and emerging technologies that will be deployed by businesses that are bandwidth intensive.



Category 5e Inadequate in Near Future


Cabling will be migrating from being behind walls to above ceilings, where it can end at a wireless access point (WAP). Much more cabling will be needed to serve an increasing utilization of WAPs for numerous users.


The advent and growth of new Wave 2 WiFi devices, which transmit at data at ranges of 1 Gbps up to perhaps 7 Gbps, will require faster Ethernet links for the connection of these WAPs. Installing Category 6A cabling may be the only effective solution for companies. The need for average speeds greater than 1G is increasing, perhaps to 10G. Category 5e is incapable of carrying speeds of 10 Gbps speeds over a required distance of 100 meters.


An emerging technology using balanced twisted-pair cabling, HDBaseT is used to transmit uncompressed HD video, audio, Ethernet, control, and power over 100 meters. Category 5e will be unable to support it, while Category 6A cabling is capable.


4-cable pair PoE, the next power over Ethernet standard, provides power more efficiently. However, the gauge of cable must grow in order for the reduction of resistance and permit higher power delivery. Consequently, 4-pair PoE has superior performance on Category 6A 23 AWG than Category 5e 24 AWG.



Cabling Standards Recommend Category 6A


For certain organizations, such as educational institutions, commercial buildings, data centers, and healthcare facilities, new installations require or recommend at least Category 6 cabling. Even though Category 6A may require greater capital expenditure than Category 5e cabling, costs will be decreased in the long term. A company’s network will be future proofed and will be capable of supporting new applications and emerging technologies.

Reviewing Tools for Cabling Installation

30 May 2015

 Network Cabling, Data Cabling, Cat5e,Cat6/6a CablingCabling installation requires a lot of expertise. This is important due to the complexity of networks cables for data and communication services.  There are tools installers use to install and test cables. Some of the instruments include carts and caddies.



Basic Implements


Network carts and caddies hold cable spools for easier pulling. Reels can be set up on the wire cart which can hold 500 and 1000 foot reels. Cables are mounted on bars that slip through bored holes on the mounting framework. The cart contains a large, wide base that prevents tipping when you pull the cable.  Wire caddies secure smaller cable spools which come in lengths of 500 feet or less. And it has dividers that prevent the wires from becoming crisscrossed and twisteded.



Termination Tools


The appropriate termination tool increases productivity. It allows installation and termination of Cat5e and Cat6 jacks onto the connectors on a patch panel.


This "punch down tool" ensures accuracy and consistency. There are three categories: manual, impact and multi-wire. Cable installers can opt for a manual but most consider the impact tool to be the best option.


The fundamental impact instrument is fitted with a spring-loaded head which can be triggered by the installer. Not much force is needed. The spring is released automatically after being compressed. Modern multi-wire tools like the Jack Rapid punch down tool can terminate jacks eight times faster.


You can use several interchangeable blades for various impact tools. However, this depends on your cabling system. The advantages of this tool are its speed, user-friendliness and uniformity of termination. Sophisticated models consist of fixed blades that cut off leftover wire instantly instead of having to use wire cutters. These new products include a handle that is easy to hold, a disposable blade head and fixed band that holds the jack in place.



Other Useful Tools


You might need professional shears to ensure a quick, clean, and accurate cut.  Each job requires cutting of cables and trimming of excess wires.  A premium cable stripper guarantees immediate and hassle-free elimination of exterior insulation from multi-core cables, unshielded twisted as well as shielded twisted pairs. The flexible depth gauge will give better results.  Refrain from using pocket knives or ordinary scissors because you will probably end up damaging the cable. Other functional tools for cable installation are can wrenches for demarcation point boxes; crimping pliers; knives for splicing cables; voltage detectors; modular plug crimpers for telephones; and, probe picks to detect loose or broken connections.
