Top Ten Tips for Business Data Cabling – Part 2

22 Aug 2018

cabling, network cabling,Washington DC As discussed in Part 1, business cabling projects can be a challenge to properly design, install, and accomplish on schedule. The key to success is finding an experienced team that will provide structured cabling services of high quality. Part 2 will discuss Maintaining Standards, Planning Well, Respecting Regulations, Staying Up-to-Date, and Testing Infrastructure.

Maintaining Standards

Maintain the established standards and best practices of structured cabling. Neglecting to do so will probably reduce quality and the efficiency of a data network. For guidance, refer to the standards set forth by the Telecommunications Industry Association.

Planning Well

Planning well will help future proof your organization. Do your best in estimating what your company will need for the next five years. CAT5E is now the standard, and it can support a maximum of 1000 Mbps. If your company needs more bandwidth, CAT6 is rated at a maximum of 10 Gbps. Re-cabling soon after installation will be disruptive and expensive.

Respecting Regulations

Compliance with codes, laws, and ordinances typically protects the lives of employees and first responders. A company found to be violating regulations will be fined and required to rewire the cabling so it is up to code. In the event of injury or death that is attributable to a violation, individuals found responsible may be held financially and perhaps criminally liable.

Staying Up-to-Date

Staying current with technological developments and regulations related to structured cabling and IT infrastructure will allow you to provide guidance to your company that has foresight. Knowledge of trends will let you anticipate what your IT infrastructure will need in the future.

Testing Infrastructure

Testing IT infrastructure during the installation of cabling is good practice. For efficiency, tests should be performed in phases to detect and fix problems quickly. Testing only after the installation of hundreds of feet of cabling will discover issues far too late and result in time wasteful revisions, repair, or replacements.

Improve Data Center Reliability with Structured Cabling – Part 1

22 Nov 2017

Stu Kushner

Data Cabling,Structured Cabling, Cabling Design-Washington DC Cabling systems were once proprietary prior to the 1990s, which was a major problem for data centers. Each modification required vendor-specific knowledge of each component of the cabling system. In 1991, the TIA/EIA-568 standard was introduced to bring about structured cabling systems.

Although 5% percent of a network budget is currently spent on structured cabling, 59% of downtime can be attributed to it. Most downtime results from not adhering to standards. Data center efficiency can be increased by proper planning and implementing structured cabling principles. Structured cabling best practices should be the foundation of every data center.

Proper Planning

Designing proper cable runs, identification of cable types, the process of network verification, planning for future expansion, and accurate documentation are all part of the proper planning for structured cabling. Lacking these, a data center would be disorganized and chaotic.

A data centers begin at the MDA (Main Distribution Area), single or multiple HDA(s) (Horizontal Distribution Area), as well as the required equipment and spacing to allow cable access. The Main Distribution Area is the location of core networking equipment. The cross-connects of HDAs are utilized for the distribution of cables to the EDA (Equipment Distribution Area). A well-organized data center is the product of a structure that is well-planned.

Best Practices

Proper Standards –To attain high levels of proficiency, cabling standards, which are revised every five to ten years, must be followed. Remaining up-to-date will allow a data center to be more adaptable to changes of technology. American data centers now comply with the TIA/EIA-568 standard developed by the TIA (Telecommunications Industry Association), while business and companies located overseas comply with the ISO/IEC IS 11801.

Cable Identification System – In addition to standards, implementing an identification system utilizing colors and labels will assist managers in data center organization. A sound system will conserve both time and money over the long term. Addressing problems or even maintaining aging equipment is eased by a well-defined and easily understandable cable identification system.

8 Network Cabling Mistakes to Avoid – Part 2

14 Nov 2017

Stu Kushner

As discussed in Part 1, the improper I can result in poor network performance, maintenance issues, and concealed expenses. Part 2 will discuss four more network cabling errors to avoid. Remember to consult with a cabling company that is experienced and provides excellent service.

Mistake No. 5: Ignoring Distance Limitations

The standard distance limitation for UTP cabling with Ethernet at 1 Gbps is 100 meters. For cabling used for 10 Gbps or 40 Gbps, it is important to be aware of the distance limitations of the kind of cabling that will be used. Let’s say your project plans to run 10 Gbps for a maximum of 100 meters over UTP cabling. This will require utilizing at least CAT 6A cabling.

Mistake No. 6: Bypassing Codes

Bypassing local codes may result in endangering first responders. In most facilities, it is prohibited to use PVC-jacketed cabling within air handling spaces. When PVC cabling burns, it produces poisonous fumes that can be hazardous to firefighters and other first responders who must enter the facility during an emergency.

The failure to comply with local codes with respect to low voltage cabling may result in costly fines and perhaps even being ordered to completely remove and reinstall cabling, an expensive exercise. Working with a reputable cabling service company that is knowledgeable regarding local ordinances will avoid future problems.

Mistake No. 7: Neglecting Testing

After cabling is installed, testing should be performed on every cable, using equipment that can verify functionality. The verification of cable lengths and specifications is also important. For certain transmission rates, it must be verified that the cabling is capable of adequately providing support.

Mistake No. 8: Non-Compliance with Standards

Your company’s project should comply with technical standards to ensure the proper functioning of its network. Non-compliance will make noise and interference more likely, leading to inefficiency and poor network performance.

Network cabling standards are used worldwide and are drafted by ISO/IEC, CENELEC and the Telecommunications Industry Association (TIA). TIA (USA) issues the ANSI/TIA-568 standards for telecommunications cabling in commercial facilities.

The 5 Most Common Structured Cabling Errors – Part 1

19 Oct 2017

Stu Kushner

Structured Cabling, cables Structured cabling systems are so standardized that good practices should merely entail following ISO/IEC, CENELEC or Telecommunications Industry Association (TIA) documentation for panel and outlet standards, cable pathway standards, maximum cable and patch cord lengths, patch testing standards, etc. Strictly doing so will invariably result in an installation that is professional and trouble free. In addition, as data speeds grow faster and faster, following industry standards becomes even more crucial.

Improperly installed cabling made up of shorter runs, which do not overly stress the system, may function well enough. In addition, data speeds may be quite beneath the cable specification capacity. As an example, CAT5e carrying 100Mbps and capable of 1Gbps will have ample margin of error. However, structured cabling systems still need qualified technicians for proper installation supporting maximum data speeds over the entire network as required.

The following will discuss the five most common errors of structured cabling. Remember to call an experienced and expert cabling installation team to get the best results for your company’s project.

Error No. 1

Considering cables as merely wiring is the first error. They are actually very important electronic components that provide the pathway for data from point to point within a network. These points may be a desktop PC, a network switch, server, router, and wireless access point. When you consider that cables make these connections possible, then you can understand how important it is to make sure that the cabling is of high quality and properly installed.

Error No. 2

Running data cables near power cables is the second error. Even when cables are screened, this practice is unsound. When data cables are running near and parallel to power cables, noise emitted by power cables may infiltrate data cables. As the load carried by power cables fluctuate, resulting spikes or surges may radiate into the data cables, creating undesired noise decreasing the quality of the data transmission.

Part 2 will discuss three more common errors of structured cabling.

Important Considerations for Structured Cabling

13 Sep 2017

Stu Kushner

cables,structured cabling, Network Cabling An 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.

The Organizations that Set Cabling Standards

27 May 2017

Stu Kushner

Data Cabling,Network Cabling,Atlanta GA 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.

New Standards for Cabling and Category 8 Update

20 May 2017

Stu Kushner

Data Cabling, Cat5e Cat6/6a Cabling, Washington DC The selection of proper cabling has become more crucial and also more complicated, but the process can be made easier by knowing about the choices available and updates regarding the development of Category 8 (CAT 8).

There are several organizations that determine the standards for cabling, such as the ISO (International Organization for Standardization), IEC (International Electrotechnical Commission), TIA (Telecommunications Industry Association), and CENELEC (European Committee for Electrotechnical Standardization). However, our discussion will primarily focus on ISO/IEC and TIA.

As its standard calls for 10Gb/s rates of transmission, 10GBASE-T cabling is the fastest in the market. Unable to support 10Gb/s, Category 5e does not receive 10GBASE-T standard recognition. In addition, advisories by the TIA and ISO/IEC and TIA state that new class E/category 6 cabling should not be installed to support 10GBASE T. As a result, the cabling options for new installations that meet the 10GBASE-T standards for carrying data up to 100 meters are only found in the class EA/CAT 6A, class F/CAT 7, or class FA/CAT 7A.

Regarding data centers that are newly built, ISO, along with other standards organizations, have determined that CAT 6A should be the minimum grade. The task force overseeing IEEE 802.3 40GBASE-T have drafted the baseline objectives for the future 40 Gb/s standard, which is well beyond the capabilities of CAT 6A.

Cabling of a higher category traditionally matches and surpasses the electrical and mechanical standards of what preceded it. In addition, it is backwards compatible. Although TIA calls for cabling systems to perform at CAT 6A minimum, it will not be adopting CAT 7 or 7A as determined by ISO/IEC. TIA is naming its next class of cabling, Category 8, to differentiate it from ISO/IEC standards for CAT 7 and CAT 7A.

Interestingly, the proposed performance for CAT 8 will not be meeting or exceeding CAT 7A standards for up to 1 GHz. For example, regarding parameters for internal crosstalk, CAT 7A is superior to CAT 8 by more than 20 decibels.
