纤维光学互连设备和无源元件.基本试验和测量规程.第3-50部分:检查和测量.光学空间开关串扰

[中文适用范围]： IEC 61300 的这一部分描述了测量多端口 M x N（M 个输入端口和 N 个输出端口）光纤空间交换机的端口之间光信号串扰的过程。串扰定义为来自未连接的输入端口的输出端口的光功率与来自连接的输入端口的输出端口的光功率之比。 [外文原描述]： IEC 61300-3-50:2013 describes the procedure to measure the crosstalk of optical signals between the ports of a multiport M x N (M input ports and N output ports) fibre optic spatial switch. The crosstalk is defined as the ratio of the optical power at an output port which comes from the unconnected input port, to the optical power at the output port which comes from the connected input port. Keywords: measure the crosstalk of optical signals The contents of the corrigenda of January 2015 and of July 2015 have been included in this copy.
