The Telecommunications Industry Association (TIA) TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) has issued a call for interest for document TIA-568.2-D initially titled Balanced Twisted-Pair Telecommunications Cabling and Components Standard. This document is a revision to ANSI/TIA-568-C.2, Balanced Twisted-Pair Telecommunications Cabling and Components Standard, which was published in August, 2009.
Since 2009, there have been significant advances in telecommunications cabling technology, test procedures, and expansion of the capability of balanced twisted pair-cabling to support additional applications. ANSI/TIA-568.2-D is part of the ‘568 family’ of Standards including ANSI/TIA-568.0-D (Generic Telecommunications Cabling for Customer Premises), ANSI/TIA-568.1-D (Commercial Building Telecommunications Infrastructure Standard), and ANSI/TIA-568.3-D (Optical Fiber Cabling and Components Standard).
The significant anticipated changes to this document are:
- ANSI/TIA-568-C.2-1, containing category 8 specifications, will be incorporated into the revision
- ANSI/TIA-568-C.2-2, describing alternative test procedures for category 6A patch cords, will be incorporated in the new revision
- Test procedures for cabling and components have been refined and extrapolated up to 2000 MHz from the previous maximum frequency of 500 MHz
- Resistance parameters needed for support of remote powering applications have been added as additional parameters
- This document will also incorporate updated references and links to other TIA TR-42 standards that have been revised in the past five years.
- This Standard will supersede ANSI/TIA-568-C.2 and its addenda ‘C.2-1 and ‘C.2-2 and is intended to incorporate the content of those Standards.
- The stakeholders may include, but are not limited to: Cable and connector manufacturers, end users, system developers, installers, consultants, field tester manufacturers and users.
- TIA is actively seeking participation in these projects from the user and general interest communities.
