TIA Published New Standard TIA/EIA-568-B.2-1

The Telecommunications Industry Association (TIA) has published two new standards, 'Commercial Building Telecommunications Cabling Standard, Part 2: Balanced Twisted Pair Cabling Components, Addendum 1 -- Transmission Performance Specifications for Four-Pair 100 Category 6 Cabling. The document is addendum no. 1 to TIA/EIA-568-B.2.

The document specifies requirements for insertion loss, near-end crosstalk (NEXT) loss, equal level far-end crosstalk (ELFEXT), return loss, propagation delay, and delay skew requirements for 100 * four-pair category 6 cabling, cables and connecting hardware. The standard also specifies NEXT loss and return loss requirements for modular plug cords. For cabling and cable NEXT loss and ELFEXT, both worst pair-to-pair and multi-disturber power sum requirements are specified. Balance recommendations are provided for category 6 connecting hardware and cables. In addition to these requirements and recommendations, category 6 cabling, cables, cords and connecting hardware shall meet or exceed all the requirements of ANSI/TIA/EIA-568-B.1 and ANSI/TIA/EIA-568.B-2. Compliance with this standard does not imply compatibility with cabling having nominal impedance values other than 100.

TIA/EIA-568-B.2-1 was created by TIA TR-42.7 Subcommittee on Telecommunications Copper Cabling Systems. To obtain copies of the documents, please contact Global Engineering Documents at (800) 854-7179 or visit http://global.ihs.com. EC
