标准摘要
[中文适用范围]： 本部分 IEC 61300 提供了基于保偏 (PM) 光纤的单模保偏 (PM) 无源光学元件的偏振消光比 (PER) 的测量方法。本文档还提供了检测 PM 元件的主轴输入和输出方向的方法，以及估算键控精度（即主轴与连接器存在的机械参考导向键之间的角不对齐度）的方法。 [外文原描述]： IEC 61300-3-55: 2020 provides methods for measuring the polarisation extinction ratio (PER) of single-mode, polarisation maintaining (PM) optical components based upon PM fibres. This document also provides methods for detecting the input and output orientation of the PM components' principal axes as well as methods for estimating the keying accuracy, i.e. the angular misalignment between the principal axes and the mechanical reference guide key of the connectors, if these are present.
