光纤互连设备和无源元件 非波长选择性光纤分支设备 第1部分：通用规范

[中文适用范围]： 本部分 IEC 60875 适用于所有具备以下特征的非波长选择性光纤分支器件： – 它们是无源的，即不包含任何光电子或其他换能元件； – 它们具有三个或更多端口用于光功率的进入和/或离开，并按预定方式在这些端口间共享光功率； – 端口为光纤或光纤连接器。 本标准确立了关于光、机械和环境特性的统一要求。 [外文原描述]： IEC 60875-1:2015 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 the entry and/or exit of optical power, and share optical power among these ports in a predetermined fashion; - the ports are optical fibres, or optical fibre connectors. This standard establishes uniform requirements for the optical, mechanical and environmental properties. This sixth edition cancels and replaces the fifth edition published in 2010 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - removal of terms and definitions for splitter, coupler, symmetric non-wavelength-selective branching device, asymmetric non-wavelength-selective branching device; - addition of terms and definitions for bidirectional non-wavelength-selective branching device and non-bidirectional non-wavelength-selective branching device, removal of assessment level. Keywords: non-wavelength-selective fibre optic branching devices, uniform requirements for the optical, mechanical and environmental properties.
