As mentioned in Part 1, a structured cabling system is a type of open network structure that can be used by data, telephony, access control, building automation, and other systems. Its advantages are operational flexibility and economy. Part 2 will describe each of structured cabling's six subsystems below.

The Six Subsystems

1. Entrance Facilities

Entrance facilities house the protection devices, network demarcation points, cables,  connecting hardware, and other equipment that connect to private network cabling or the access provider. Connections between the inside building and outside plant cabling are included.

2. Equipment Room

Featuring environment control, the centralized area for telecommunications equipment is typically more complex than a telecommunications room. Usually containing the main cross-connect, it may also house the horizontal and intermediate cross-connects.

3. Backbone Cabling

Backbone cabling provides the interconnections between entrance facilities, telecommunications rooms, equipment rooms, etc. Typically, backbone cabling is comprised of fiber optic cables, intermediate and main cross-connects, mechanical terminations, and patch cables utilized for backbone-to-backbone cross-connections.

4. Telecommunications Room

Housing the terminations of backbone and horizontal cables to connecting hardware with patch cords or jumpers, a telecommunications room may also house the intermediate cross connects or main cross connect for different portions of the backbone cabling system. This space is a controlled environment containing telecommunications equipment, connecting hardware, and splice closures.

5. Horizontal Cabling

Extending from the work area’s telecommunications information outlet to the telecommunications room, the horizontal Network Cabling consists of horizontal cables and mechanical terminations, along with the jumpers and patch cords located in the telecommunications room. The system may also incorporate consolidation points and multi-user telecommunications outlet assemblies.

6. Work Area

The work area’s components typically extend from the telecommunications outlet/connector end of the horizontal cabling system to the work area equipment. At least two telecommunications outlets should be installed in every work area. If utilized, multi-user telecommunications outlet assemblies (MUTOAs) are a component of the work area.

Cabling 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.

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.

As mentioned in Part 1, modern data centers must be flexible, scalable, reliable, and manageable, making best practices required. Part 2 will cover cabling for Modular Data, High Density/High Port Count Fiber Equipment, and Standards.

Modular Data

Increasing in popularity, modular cabling systems for fiber and copper connectivity introduces the plug-and-play concept, which simplifies cable installation and significantly decreases costs and labor. Typically, cables are factory-terminated and tested.

While modular cabling is less costly when the infrastructure is modified in-house, it will not be as flexible because of the possible required commitment to a vendor for ongoing compatibility.

High Density/High Port Count Fiber Equipment

When networking equipment gradually grows in density and port counts rise to several hundred, the proper management of the connected cabling will also require increased effort.

In the past, the direct connection of cables to individual ports of equipment with low port-counts was thought to be manageable. Unfortunately, the same task will be very time consuming for high-density/high-port-count equipment. Eventually, the addition or removal of cables directly connected to these ports will be almost impossible.

The utilization of Multifiber Push-On (MPO) cable assemblies featuring a single connector at one end of cable and multiple duplex breakout cables at the other end will ease cable management.

The concept revolves around pre-connecting high-density/high- port-count Lucent Connector (LC) equipment with LC-MPO fan-out cable to dedicated MPO modules inside a dedicated patch panel. Once completely cabled, this patch panel will work as "remote" ports. Ideally the patch panels should be located on top of the cabling equipment to facilitate access to overhead cabling. This method significantly decreases cluttering of equipment and cables, resulting in improved cable management.

Standards

The ISO (International Organization for Standardization) and TIA (Telecommunications Industry Association) are the main organizations that develop structured cabling standards for the industry. IEEE (Institute of Electrical and Electronics Engineers) committees do the testing and then set performance specifications.

Standards compliance makes sure that systems function at specified levels, allows backward compatibility, and a greater variety of equipment will be available internationally. Widespread global acceptance of standards allows the sourcing and use of equipment manufactured by different countries.

Color Identification and Naming Scheme will be discussed in Part 3.

The structuring of cabling will result in better organization and easier management of the cables. If you are a building manager or business owner, you may already know a bit about structured cabling. You may be currently thinking about its installation in your premises. In the most basic terms, structured cabling allows for several devices like computers and telephones to be connected via a cabling system infrastructure. The following discusses several benefits of structured cabling for a facility or office. Consult with experienced structured cabling professionals to get the best results.

Adaptability

Structured cabling is technology that allows business managers to plan and prepare for the future, making its implementation a valuable investment. Structured cabling that installs a newer cable such as Cat 6 will provide adequate bandwidth, making it viable for an extended period as a business’ IT needs gradually expand. The high bandwidth of a structured cabling system will also give a business the increased ability to adapt newer applications, devices, and technologies.

Diagnosis and Repairs Made Easier

Whenever issues occur on multiple, disorganized cabling systems, determining the source of the problems will be difficult. Although structured cabling is a unified system, it is organized in segments, making it much easier for technicians to locate malfunctions and repair them.

Flexibility at Lower Costs

The people, equipment, and offices of an organization are not static. Businesses evolve and restructure as time passes. Employees of a department may have to move to another area. The entire area of an office may also need renovation. Typically, changes like these grind business to a halt, hurting the bottom line. However, a structured cabling system allows a company’s staff to move to another part of an office, connect, resume working, and remain productive without missing a beat.

Networking

Employees will also be able to connect their devices into any outlet of a structured cabling system as opposed to a particular wire, promoting flexibility and productivity. In addition, a structured cable system will be able to convey data in multiple forms, allowing staff on a network to connect with other computers, servers, printers, and telephones.

Simplified Management

One of the greatest advantages of a structured cabling system is the elimination of disorganized and unsightly wires. The replacement of a configuration using multiple cabling with a structured cabling system will result in easier and less costly management by technicians as they will save time on repairs and restructurings.
