IEC 61156-5:2009

Multicore and symmetrical pair/quad cables for digital communications - Part 5: Symmetrical pair/quad cables with transmission characteristics up to 1 000 MHz - Horizontal floor wiring - Sectional specification

IEC 61156-5:2009(E) describes the cables intended primarily for horizontal floor wiring as defined in ISO/IEC 11801. It covers individually screened, common screened and unscreened pairs or quads. The transmission characteristics and the frequency range of the cables are specified at 20 °C. Those cables are intended to be used to support the delivery of low voltage and power applications such as IEEE 802.3af (Power over Ethernet) and IEEE 802.3at (Power over Ethernet Plus). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- new requirements for new Cat6A and Cat7A cables;
- revised requirements and tests for Cat5e, Cat6 and Cat7 cables. The contents of the corrigendum of February 2010 have been included in this copy. This publication is to be read in conjunction with IEC 61156-1:2002.
