Terminology

Terminology

Cross-connect (a facility enabling the termination of cable elements and their connection by patch cord or jumper).

Distributor (a facility enabling the termination of cable elements and their connection by patch cord or jumper).

MC (Main Cross-connect)

CD (Campus Distributor)

IC (Intermediate Cross-connect)

BD (Building Distributor)

HC (Horizontal Cross-connect)

FD (Floor Distributor)

TO (Telecommunications Outlet/connector)

TO (Telecommunications Outlet)

CP (Consolidation Point) An interconnection scheme that connects horizontal cables that extend from building pathways to horizontal cables that extend into work area pathways.

Consolidation Point, a location in the horizontal cabling where a cable may end, which is not subject to moves and changes, and another cable starts leading to the TO which adapts to changes
- or-
a location for interconnection between horizontal cables extending from building pathways and horizontal cables extending into furniture pathways

Engineering Approach

Engineering Approach

Not applicable. Field testing for verification only.

Link performance determines compliance.

Design Approach

Design Approach

Design constraints, component specifications, and installation methods determine compliance.

Design constraints, component specifications, and installation methods determine an alternate means of compliance.

Connector Termination

Connector Termination

All pairs shall be terminated at the outlet.

Partial termination at the 100 W or 120 W outlet is permitted.

Pair untwist shall not exceed 13mm (0.5 in.) for category 5e or higher cables. Pair-untwist for category 3 shall be within 75mm (3 in.) from the point of termination.

In accordance with manufacturer’s guidelines.

Categories of Cabling Performance

Categories of Cabling Performance

Category 3 is specified to 16 MHz.

Class C is specified to 16 MHz.

Category 5e is specified to 100 MHz.

Class D is specified to 100 MHz.
An Optical Class is also specified.

Category 6 is specified to 250 MHz

Class E is specified to 250 MHz.

Class F is specified to 600 MHz.

Note: For TIA standards, the term “category” is used to specify both components and cabling performance. For ISO/IEC, CENELEC and other cabling standards outside of the U.S. and Canada, the term “category” is used to describe component performance (i.e., cable and connecting hardware). The term “class” is used to describe cabling (i.e., link and channel) performance.

Performance Specification

Performance Specification

Stranded Cable Attenuation = 20% worse than solid requirements for UTP, 50% worse for ScTP.

Stranded Cable Attenuation = 50% worse than solid requirements for both UTP and ScTP.

Hybrid requirements call for power sum margin + 3dB over pair-to-pair limit.

Hybrid requirements call for 6 dB better PSNEXT between cable units than the PSNEXT specified for the cable.
