IEC 61156-5:20 09(E)描述了主要用于ISO/IEC 11801中定义的水平地板布线的电缆。它涵盖了单独筛选、共同筛选和未筛选的对或四对。电缆的传输特性和频率范围规定为20°C。这些电缆旨在用于支持低压和电力应用的传输,例如IEEE 802.3 af(以太网供电)和IEEE 802.3 at(以太网供电增强版)。本版构成技术修订版。与上一版相比,此版本包括以下重大技术变更:-对新的Cat6A和Cat7A电缆的新要求;-修订了Cat5e、Cat6和Cat7电缆的要求和测试。2010年2月更正的内容已纳入本副本。本出版物应与IEC 61156-1:20 02一起阅读。
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.
