Structured cabling is an organized, standardized approach to a building’s telecommunications and data cabling infrastructure.  For instance, a well designed and installed structured cabling system will deliver reliable performance as well as accommodating moves, additions and changes (MAC).


Unlike traditional point-to-point cabling, a structured cabling system avoids the jungle of wiring and can carry increasing data at high rates. 

Here are some of the benefits:


Structured cabling standards allow for consistent design, installation and uniform documentation. The American National Standards Institute (ANSI) and TIA/EIA regulate a set of standards that provide guidelines for cabling professionals. Therefore, ensuring this is achieved in data center design, management and operation.


Due to the organization of a structured cabling system, you can reduce power and maintenance costs. In addition, it eliminates the excessive costs of locating and rectifying network issues.


The potential for human error is drastically reduced. These mistakes can cause flow disruptions and network downtime. In a structured cabling system, there is organization and easy identification that helps reduce the risk of downtime.


Structured cabling is flexible and can accommodate moves, adds and changes quickly. This is achieved by cross connects in the main distribution area (MDA) versus running long patch cords from equipment racks.


Cable and port tracing becomes a much easier job. This logical, organized approach makes changes easier, thus saving you time.


A structured cabling system will look much cleaner than a point-to-point method. For example, changes are done in the MDA versus at the hardware. This allows the cabling in front of the switch to remain aesthetically pleasing.


In one word, structured cabling systems reflect “organization”. It takes an organized approach to cabling infrastructure.

Medium Key Components to Form a Structured Cabling System

Six Subsystems of a Structured Cabling System


1. Entrance Facilities

Entrance facilities contain the cables, network demarcation point(s), connecting hardware, protection devices and other equipment that connect to the access provider or private network cabling. It includes connections between outside plant and inside building cabling.

2. Equipment Room

The environmentally controlled and centralized space for telecommunications equipment is usually more complex than a telecommunications room or telecommunications cabinet. It usually houses the main cross-connect panels and may also contain the intermediate cross-connects, horizontal cross-connects, or both.

3. Backbone Cabling

The backbone cabling provides interconnection between telecommunications rooms, equipment rooms, access provider spaces and entrance facilities.

4.  Telecommunications Enclosure and Telecommunications Cabinets

These locations house the terminations of horizontal and backbone cables to connecting hardware including any jumpers or patch cords. It may also contain different portions of the backbone cabling system. The locations also provide a controlled environment to house telecommunications equipment, connecting hardware and splice closures serving a portion of the building.

5. Horizontal Cabling

The horizontal cabling system extends from the work area’s outlet to the telecommunications room or telecommunications cabinet. It includes horizontal cable, jumpers and patch cords. The maximum horizontal cable length is 90 m (295 ft.).

6. Work Area

Work area components extend from the outlet /connector end of the horizontal cabling system to the work area equipment. It is recommended that a minimum of two outlets are provided for each work area.
