What is Structured Cabling?

A structured cabling system (SCS) is a set of cabling and connectivity

products that integrates the voice, data, video, and various

management systems of a building

Benefits of Structured Cabling

• Consistency & Cost reduction

• Support for multi-vendor equipment

• Simplify moves/adds/changes

• Simplify troubleshooting

• Support for future applications

• Fault Isolation

Standards

Elements of Structured Cabling Systems

• Entrance Facilities

• Equipment Rooms

• Backbone Cabling

• Horizontal Cabling

• Telecommunications Rooms or Telecommunications

Enclosure

• Work-Area

Entrance Facilities

• Contain the cables, network demarcation

point(s), connecting hardware, protection

devices and other equipment that connect

to the access provider (AP) or private

network cabling.

• Includes connections between outside

plant and inside building cabling.

Equipment Rooms

The environmentally controlled

centralized space for

telecommunications equipment is

usually more complex than a

telecommunications room (TR) or

telecommunications enclosure (TE).

Backbone Cabling

The backbone cabling provides

interconnection between

telecommunications rooms,

equipment rooms, access

provider (AP) spaces and

entrance facilities.

Backbone Cabling

• The wiring used for backbone cabling may be either copper or fiber optic.

• Recommended backbone cable maximum distance limitations include:

• · Voice grade 100 ohm UTP 800 meter limitation

• · STP data grade 150 ohm 90 meter limitation

• · Multimode 62.5/125μm fiber 2,000 meter limitation

• · Patch cable 3 - 6 meter limitation

Horizontal Cabling

The horizontal cabling system

extends from the work area’s

telecommunications information

outlet to the telecommunications

room (TR) or

telecommunications enclosure

(TE).

Telecommunications Room

A Telecommunications Room

houses the terminations of

horizontal and backbone

cables to connecting

hardware including any

jumpers or patch cords.

Work area

Work area (WA) components

extend from the

telecommunications

outlet/connector end of the

horizontal cabling system to

the WA equipment.

UTP Color Coding

To distinguish between pairs, they are colored each pair has

designated Tip and Ring conductors. Pair 1 can therefore be

designated T1 and R1. Both UTP & STP conform to this standard

• T1 - White Blue/Blue White - R1

• T2 - White Orange/Orange White - R2

• T3 - White Green/Green White - R3

• T4 - White Brown/Brown White - R4
