标准摘要
[中文适用范围]： 本部分规范涉及 IEC 61156-1 和 IEC 61156-7。本文所述电缆的额定频率高达 1 200 MHz，专门设计用于构建 ISO/IEC 11801 和 ISO/IEC 15018 中定义的接线@设备@和工作区电缆。它涵盖具有四个单独屏蔽 (STP) 对的电缆。电缆可以在电缆芯上设有公共屏蔽。传输特性是针对 4 MHz 至 1 200 MHz 频率范围以及 20 Ω 指定的。这些电缆可用于同时使用多达四对的各种通信通道。从这个意义上说，本分规范提供了系统开发人员评估新系统所需的电缆特性。本部分规范涵盖的电缆旨在以通信系统中通常遇到的电压和电流运行。这些电缆不适合与低阻抗源一起使用，例如公用事业干线的电源。 [外文原描述]： IEC 61156-8:2009(E) relates to IEC 61156-1 and IEC 61156-7. The cables described herein are specified up to 1 200 MHz and are specifically designed to build patch, equipment, and work area cables as defined in ISO/IEC 11801 and ISO/IEC 15018. It covers a cable having four individually screened (STP) pairs. The cable may be provided with a common screen over the cable core. The transmission characteristics are specified for a frequency range 4 MHz to 1 200 MHz and at 20 °C. The contents of the corrigendum of July 2009 have been included in this copy.
