Structured Cabling – Design | Components | Benefits

My Post

Structured cabling system is defined as complete telecommunications cabling infrastructure system and associated hardware, a number of standardized smaller elements which serves a wide range of uses, such as to provide telephone service or transmit data through a computer network, predictable performance, perform modifications in the system, reduce redundancy.

Structured cabling design:

In a structured cabling system, a series of patch panels (device) is used to create a structure that allows for hardware ports to be connected to a patch panel at the top of the rack. That patch panel is then connected to another patch panel via a trunk (multi-fiber assembly designed for use in conveyance) in the MDA (main area of distribution). In the case of Point-to-point cabling refers to a data center cabling system comprised of “jumper” fiber cables that are used to connect one switch or server. It needs new cable for each connection which is suitable only for small business.

Structured Cabling is the standardized architecture and components for communications cabling specified by the EIA/TIA (telecommunications set) TR42 (cabling infrastructure). The MDA is the key aspect of structured cabling where all the MAC’s (Moves, Add, and Changes) can be made with short length patch cords.

Structured cabling components:

Six subsystems need to form structured cabling.

Horizontal cabling

The horizontal cabling is all the cabling between telecommunications outlet in the work area and patch cords located in the telecommunications room.

Backbone Cabling

Backbone cabling is also known as vertical cabling. It offers the connectivity between telecommunication rooms provides space and facility.

Work Area

The work area has space contains cable components are used between communication outlets and end-user telecommunications equipment.

Telecommunications Room

Telecommunications closet is an enclosed area like a room contains telecommunications equipment, distribution frames, and cable terminations and cross-connects.

Equipment Room

Telecommunications room is an enclosed area to have telecommunications equipment, cable terminations, and cross-connects.


Entrance facility encompasses the cables, network demarcation point, connecting hardware, protection devices and other equipment that connect to the access provider or private network cabling.
