纤维光学互连器件和无源元件.纤维光学空间开关.第1部分:总规范

[中文适用范围]： IEC 60876 的这一部分适用于具有以下所有一般特征的光纤开关： ?它们是无源的，因为它们不包含光电或其他转换元件； ?C 它们具有一个或多个用于传输光功率的端口以及可以在这些端口之间路由或阻止功率的两种或多种状态； ?C 端口为光纤或光纤连接器。 [外文原描述]： IEC 60876-1:2012 applies to fibre optic switches possessing all of the following general features: - they are passive in that they contain no optoelectronic or other transducing elements; - they have one or more ports for the transmission of optical power and two or more states in which power may be routed or blocked between these ports; - the ports are optical fibres or fibre optic connectors. This fourth edition cancels and replaces the third edition published in 2001. It constitutes a technical revision. The changes with respect to the previous edition are to remove quality assessment procedures and to reconsider definitions. Key words: fibre optic switches
