光纤互连器件和无源元件 - 光纤循环器 - 通用规范

[中文适用范围]： 本国际标准适用于光纤领域中使用的具有以下所有特性的循环器： ?它们是不可逆光学器件@，其中每个端口要么是光纤，要么是光纤连接器； ?C 根据 IEC TS 62538 中提供的分类和定义，它们是无源器件； ?C 它们具有三个或更多用于定向传输光功率的端口。附件 A 中描述了光环行器技术的示例。 [外文原描述]： IEC 62077:2015 applies to circulators used in the field of fibre optics bearing all of the following features: - they are non-reciprocal optical devices, in which each port is either an optical fibre or fibre optic connector; - they are passive devices in accordance with the categorization and definition provided in IEC TS 62538; - they have three or more ports for directionally transmitting optical power. An example of optical circulator technology is described in Annex A. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: harmonization of some terms and definitions with other generic specifications, deletion of assessment level.
