标准摘要
[中文适用范围]： 本文档描述了当执行操作能量被施加或移除以改变光纤空间开关的状态时，测量开关的开关时间及相关性能参数的一种方法。 [外文原描述]： IEC 61300-3-21:2019 describes a method to measure the switching time and related performance parameters of a fibre optic spatial switch when the actuation energy is applied or removed to change the state of the switch. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - changes to remove redundant overlap with IEC 60876-1; - clarifications to definitions and diagrams; - generalization of the detection apparatus beyond an oscilloscope. Keywords: switching time, performance parameters of a fibre optic spatial switch, actuation energy
