IEC 60794-2-50:2023作为IEC 60794-2-50:2023 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 60794-2-50:2023规定了用于端接电缆组件或用于无源元件端接的单工和双工光缆的要求。这第三版取消并取代了2020年出版的第二版。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: a)在规范性参考文献中增加了IEC 60793-1-46和IEC 60794-1-211； b)将拉伸试验的载荷持续时间从5分钟改变为10分钟； c)明确了用于扭转试验的夹具之间的距离为电缆直径的125倍，但不小于0.3 m；d)建议室内单工和双工电缆的温度为-10°C和+60°C，并根据IEC 61753-1中的运行服务环境，包括C类、CHD、OP和OPHD的低温和高温，用于温度循环和收缩测试； e)将收缩测试标准更新为IEC 60794-1-211，F11A，并将要求更改为最大20mm； f)用改进的描述替换了火灾性能的文本。

IEC 60794-2-50:2023 is available as IEC 60794-2-50:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60794-2-50:2023 specifies requirements for simplex and duplex optical fibre cables for use in terminated cable assemblies or as used for termination of passive components. This third edition cancels and replaces the second edition published in 2020. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) added IEC 60793-1-46 and IEC 60794-1-211 to the normative references;
b) changed the load duration for the tensile test from 5 min to 10 min;
c) clarified the distance between the clamps for torsion test to 125 times cable diameter, but not less than 0,3 m;
d) recommended the temperatures –10 °C and +60 °C for indoor simplex and duplex cables and included the low and high temperatures for category C, CHD, OP and OPHD according to the operating service environments in IEC 61753-1 for temperature cycling and shrinkage testing;
e) updated the shrinkage test standard to IEC 60794-1-211, F11A, and changed the requirement to maximum 20 mm;
f) replaced the text for the fire performance with an improved description.
