TIA ANSI/TIA/EIA-568-B.2-1 PDF

PURPOSE AND SCOPE

This Standard 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 Ω 4-pair category 6 cabling, cables, and connecting hardware. This Standard also specifies near-end crosstalk (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 Ω.
