IEC 61156-8:20 23作为IEC 61156-8:20 23 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61156-8:20 23涉及IEC 61156-1和IEC 61156-7。本文所述的电缆指定高达1200MHz，并且专门设计用于构建工作区电缆。它覆盖了一根有四对单独屏蔽（S/FTP）的电缆。电缆可以在电缆芯上设置有公共屏蔽。本部分规范涵盖的电缆旨在在通信系统中通常遇到的电压和电流下工作，并支持DC低压远程供电应用的交付。这些电缆不打算与低阻抗源结合使用，例如公共事业干线的电力供应。第二版取消并取代了2009年出版的第一版，以及修正案1:20 13。与上一版相比，此版本包括以下重大技术变更:a.使条款与IEC 61156-1:20 23保持一致；b.附加参考IEC 62153-4-9测试方法（三轴），用于与IEC 61156系列的所有其他部分一致的耦合衰减测量；c.纳入空白详细规范。

IEC 61156-8:2023 is available as IEC 61156-8:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61156-8:2023 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 work area cords. It covers a cable having four individually screened (S/FTP) pairs. The cable can be provided with a common screen over the cable core. The cables covered by this sectional specification are intended to operate with voltages and currents normally encountered in communication systems and support the delivery of DC low voltage remote powering applications. These cables are not intended to be used in conjunction with low impedance sources, for example the electric power supply of public utility mains. This second edition cancels and replaces the first edition published in 2009, and Amendment 1:2013. This edition includes the following significant technical changes with respect to the previous edition:
a. align clauses with IEC 61156-1:2023;
b. additional reference to IEC 62153-4-9 test method (triaxial) for coupling attenuation measurement to be consistent with all other parts of the IEC 61156 series;
c. incorporation of blank detail specification.
