光纤互连设备和无源元件 - 光纤无源电力控制设备 - 第1部分:通用规范

[中文适用范围]： 此部分IEC 60869适用于光纤无源功率控制器件。这些器件具有以下所有通用特征：它们是被动器件，不包含光电子或其他转换元件；它们具有两个端口，用于传输光功率并以固定或可变方式控制传输功率；端口为非连接器化的光纤尾纤、连接器化的光纤或插座。本文件为以下无源光学器件建立了通用要求：光衰减器；光熔断器；光功率限制器。本文件还提供了通用信息，包括IEC 61753-05x系列所需的术语。已发布的IEC 61753-05x系列文件列在参考文献中。 [外文原描述]： IEC 60869-1:2018 applies to fibre optic passive power control devices. These have all of the following general features: – they are passive in that they contain no optoelectronic or other transducing elements; – they have two ports for the transmission of optical power and control of the transmitted power in a fixed or variable fashion; – the ports are non-connectorized optical fibre pigtails, connectorized optical fibres or receptacles. This document establishes generic requirements for the following passive optical devices: – optical attenuator; – optical fuse; – optical power limiter. This document also provides generic information including terminology for the IEC 61753-05x series. Published IEC 61753-05x series documents are listed in Bibliography This fifth edition cancels and replaces the fourth edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the terms and definitions have been reviewed; b) the requirement concerning the IEC Quality Assessment System has been reviewed; c) the clause concerning quality assessment procedures has been deleted; d) Annex G, relating to technical information on variable optical attenuators, has been added.
