Topology or zone cabling design starts with horizontal cables running from patch panels within the TR (telecommunications room) to connections in a ZE (zone enclosure). A ZE can be installed in a ceiling, on a wall or beneath a raised floor. Next, cables originating from ZE connecting blocks or outlets lead to telecommunications outlets inside the WA (work area), equipment outlets, or straight to BAS (building automation system) devices.

Keep in mind ZE connections are creating by modular outlets or punch down blocks. No active equipment is housed in the ZE. For zone cabling deployment, experts recommend installing zone enclosures within a floor space’s populated areas that have the greatest density.

The primary element of zone cabling design is allowing flexibility in client work spaces that enable efficient MACs (moves, adds, and changes). Studies have found that zone cabling can result in considerable savings as opposed to the traditional configuration of home run work area to TR cabling. This is attributable to the fact that MACs on a home run topology need a greater amount of cabling materials and installation time for implementation.

To illustrate the savings mentioned above, we can compare a home run cabling link to a zone cabling link. Both can support a WA outlet positioned 200 ft. from the TR. In this scenario, the ZE is already cabled from the TR with extra ports for supporting additional services and positioned 50 ft. from the WA outlet. Should a second cable be required for deployment, 200 ft. of additional cable will require pulling from the telecommunications room that is designed traditionally, but just 50 ft. will require pulling with a zone cabling design.

Other important benefits derived from the utilization of zone cabling designs are considerably decreased installation and disruption times, along with cable pulling savings of 75%, which will result in significantly improving ROI (return on investment).

Part 2 will continue discussing the basics and benefits of zone cabling.

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.

If your organization is considering a new VOIP (Voice Over Internet Protocol) system, you should think about the structured cabling system needed to support it and maximize its potential. The following summarizes the advantages your digital phone system will have with a well-designed structured cabling system.

Decreased Noise

CAT 6 and CAT 6A cable provides more noise reduction than older cables. Fiber optic cabling is even better. Less noise resistance results in more static and faulty connections during phone conversations. Higher levels of noise also decrease network speed because the system is forced to retransmit data until it is no longer corrupted. Although purchasing lower quality cable saves money in the short run, it may result in long term business losses because of slower response times and annoyed customers.

Lengthened Runs

Higher quality cable will be capable of supporting longer runs that are free of artifacts and errors. Fiber optic cables are not restricted by the length of runs. It is the superior option for a data center or business telephone system because of its excellent noise resistance and high speed. Although second choices, CAT 5e to CAT 6A cabling are capable of supporting runs to 100 meters without noise. Cables that can support long runs provide greater flexibility for layouts, decreasing the need for data hubs or repeaters and increasing reliability.

Maintenance Savings

CAT 5e, CAT 6, and fiber optic cables are highly dependable. However, if they ever become faulty or the network needs to be reconfigured, a structured cabling system that is well organized and diligently marked will save time spent on maintenance. While a company’s network is down, business may be impacted, resulting in lost revenue. Tracing faults is made much easier by a sound structured cabling system.

Transmission Speed

Business is often time-sensitive, and you will want to use the highest quality cable your company can afford. CAT 6A cable is capable of supporting a maximum of 10 Gigabits per second while CAT 5e can only achieve 100 mbps. Older, less capable cables are not recommended because their slow data transmission and high noise levels cannot meet current VOIP demands.

As mentioned previously, modern data centers must be flexible, scalable, reliable, and manageable, making best practices required. Part 3 will cover Color Identification and Naming Scheme.

Color Identification

A method of fast visual identification, color coding makes management simpler, conserving time spent on the tracing of cables. Patch panel ports can also be coded, and various colored jacks and inserts are also coded. As determined by a particular manufacturer’s own color scheme, cables are available in numerous colors, each of which can be made applicable to the specific function of a cable or connection type.

Color schemes are expandable through the use of color bands at the end of every cable, using various colored sleeves and colored ports on the patch panel. However, it will also be necessary to use a secondary non-color scheme to make it possible for those who are color blind to identify the cables.

Naming Schemes

After determining the physical layout for the cabling that will be used, use a naming scheme that can be logically applied for facilitating fast and effortless identification of every cable component. Labeling can be an especially effective way to improve team communication among staff members because it makes confusion and uncertainty unlikely when a colleague must search for a particular component. Clear labeling is integral to the success of the naming scheme, and it should not be neglected.

A good naming scheme documents and labels every cable component. The following is the typical hierarchy for a naming scheme: Building, Room, Rack, Patch Panel, Workstation Outlet, Port, and Cable. Each should receive a designation indicating its location preceded by the area(s) above it. For example, Rack A03 would receive the designation SJ01-5D11-A03, if Room is designated SJ01-5D11, and Building is designated SJ01.

Upon the approval of the naming scheme, your team can begin labeling components. The team should prioritize drafting a manual that details the naming scheme and include it as part of the training program for newly hired data center administrators.

The Best Practices for Cable Component Selection will be discussed in the next series.

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.
