IEC 60794-1-31:2021作为IEC 60794-1-31:2021 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 60794-1-31:2021是一个通用规范，涵盖光纤带。本部分描述的要求适用于与采用类似技术的电信设备和装置一起使用的光纤带状电缆，特别是IEC 60794-2中的室内用光纤电缆、IEC 60794-3中的室外用光纤电缆、IEC 60794-4中的自支撑架空用光纤电缆、IEC 60794-5中的空气吹送用光纤电缆和IEC 60794-6中的室内/室外用光纤电缆。详细规范可以在IEC 60794-2和IEC 60794-3等每个应用的规范中验证。这第二版取消并取代了2018年出版的第一版。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:-已经修改了通常具有250 μ m涂层直径的光纤带的几何要求，并且已经添加了通常具有200 μ m涂层直径的光纤带的几何要求。-将“通过位置标识进行标识”和“通过色带编码和纤维着色进行标识”移至新的资料性附件A。

IEC 60794-1-31:2021 is available as IEC 60794-1-31:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60794-1-31:2021 which is a generic specification, covers optical fibre ribbons. Requirements which are described in this part apply to optical fibre ribbon cables for use with telecommunication equipment and devices employing similar techniques, in particular optical fibre cables in IEC 60794-2 for indoor use, in IEC 60794-3 for outdoor use, in IEC 60794-4 for self-supporting overhead use, in IEC 60794-5 for air blown use and in IEC 60794-6 for indoor/outdoor use. The detailed specification can be verified in specifications for each application such as IEC 60794-2 and IEC 60794-3. This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- The geometrical requirements for optical fibre ribbon with typically 250 μm coating diameter have been modified and those for the optical fibre ribbon with typically 200 μm coating diameter have been added.
- "Identification by positional identification" and "Identification by ribbon coding and fibre colouring" are moved to a new informative Annex A.
