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 61156-5:2020 describes the cables intended primarily for horizontal floor wiring as defined in ISO/IEC 11801. It covers cable designs comprising individually screened, common screened and unscreened pairs or quads. The transmission characteristics and the frequency range of the cables are specified at 20 °C. The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems Those cables are intended to be used to support the delivery of low voltage remote powering applications such as IEEE 802.3af (Power over Ethernet) or further developments for example according to IEEE 802.3at or IEEE 802.3bt. This third edition cancels and replaces the second edition published in 2009 and Amendment 1:2012. This edition includes the following significant technical changes with respect to the previous edition- additional balance levels with respect to MICE implementation by certain cabling specifications;- reference to current standards and technical reports with respect to measurement techniques and remote powering.

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.
