[中文适用范围]： IEC 60794-1-129:2025适用于与电信设备及采用类似技术的装置配合使用的光缆，以及同时包含光纤和电气导体的复合缆。本文件定义了用于确定光纤元件直通中段访问机械性能统一要求的测试方法。在本文件中，“光缆”一词也包括光纤单元、微管光纤单元等。注：有关所有类型测试方法的参考指南、一般要求和定义，请参见IEC 60794-1-2。与IEC 60794-1-21:2015和IEC 60794-1-21:2015/AMD 1:2020相比，本版进行了以下重大技术变更：a) 本文件取消并替换了IEC 60794-1-21:2015和IEC 60794-1-21:2015/AMD 1:2020中的方法E29；b) 增加了适用缆型的描述；c) 更新了图2a)、图2b)和图3；d) 增加了位移测量的描述；e) 增加了需报告的详细信息。 [外文原描述]： IEC 60794-1-129:2025 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The document defines test procedures used in establishing uniform requirements for mechanical performance-straight midspan access to optical elements. Throughout this document, the wording "optical cable" also includes optical fibre units, microduct fibre units, etc. NOTE See IEC 60794‑1‑2 for a reference guide to test methods of all types and for general requirements and definitions. This edition includes the following significant technical changes with respect to IEC 60794‑1‑21:2015 and IEC 60794-1-21:2015/AMD 1:2020: a) this document cancels and replaces method E29 of IEC 60794-1-21:2015 and IEC 60794‑1‑21:2015/AMD 1:2020; b) addition of the description for applicable cable types; c) update of Figure 2a), Figure 2b) and Figure 3; d) addition of the displacement measure description; e) addition of the details to be reported.
