Cabling Specifications Cross-Reference Chart (ANSI/TIA/EIA-568-B SERIES AND ISO/IEC 11801) 2nd Edition

ANSI/TIA/EIA-568-B Series

Commercial Building Telecommunications Cabling Standard

ISO/IEC 11801:2002 2ND Edition

Generic Cabling for Customer Premises

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)
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
Intrabuilding Backbone Campus Backbone
Interbuilding Backbone Building Backbone
Horizontal Media Choices Horizontal Media Choices
4-pair 100Ω unshielded twisted-pair (UTP or F/UTP) 4-pair 100Ω balanced cable (UTP or F/UTP)
Two fiber, 50/125µm or 62.5/125µm optical fiber Optical fiber (50µm, 62.5µm or singlemode permitted)
Backbone Media Choices Backbone Media Choices
100Ω balanced twisted-pair (UTP or F/UTP) 100Ω balanced twisted-pair (UTP or F/UTP)
50/125µm or 62.5/125µm optical fiber 62.5/125µm or 50/125µm optical fiber
Singlemode optical fiber Singlemode optical fiber
Bend Radius Bend Radius
Horizontal ≥ 4 times cable O.D. no load for UTP, 8 times cable O.D. for ScTP no load* Backbone ≥ 10 times cable O.D. Horizontal ≥ 4 times cable O.D. Backbone ≥ 6 times cable O.D. ≥ 8 times cable O.D. while pulling cables

*See ANSI/TIA/EIA-568-B.1-1 for specifications on patch cable band radius.

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 100Ω or 120Ω 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
Augmented category 6 will be specified to 500 MHz Class E, edition 2.1 will be specified to 500 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 F/UTP. Stranded Cable Attenuation = 50% worse than solid requirements for both UTP and F/UTP.
Hybrid requirements call for power sum NEXT loss margin + 3dB over pair-to-pair NEXT loss limit. Hybrid requirements call for 6 dB better PSNEXT loss between cable units than the PSNEXT loss specified for the cable.
