IEC 60875-1:20 24作为IEC 60875-1:20 24 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 60875-1:20 24适用于非波长选择性光纤分支器件，均表现出以下特征: -它们是无源的，因为它们不包含光电或其他转换元件； -它们具有三个或更多个端口，用于光功率的输入或输出或两者，并且以预定方式在这些端口之间共享光功率； -端口是光纤或光纤连接器。 本文件建立了光学、机械和环境性能的统一要求。这第七版取消并取代了2015年出版的第六版。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)从句分类中删除变体和引用扩展 b）删除条款文件中的规格系统 c)条款标准化体系中接口标准、可靠性标准和互连的去除

IEC 60875-1:2024 is available as IEC 60875-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60875-1:2024 applies to non-wavelength-selective fibre optic branching devices, all exhibiting the following features:
- they are passive, in that they contain no optoelectronic or other transducing elements;
- they have three or more ports for either the entry or exit, or both, of optical power, and share optical power among these ports in a predetermined fashion;
- the ports are optical fibres, or optical fibre connectors.
This document establishes uniform requirements for the optical, mechanical and environmental properties. This seventh edition cancels and replaces the sixth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) removal of variant and reference extensions in clause classification
b) removal of specification system in clause documentation
c) removal of interface standards, reliability standards and interlinking in clause standardization system
