IEC 62343-5-2:2018描述了1 x N固定栅极波长选择开关（WSS）端口切换期间动态串扰的测量方法。本文件的目的是针对ITU？T 50 GHz和100 GHz固定网格1 x N（N）中的公共端口，建立不同信道动态串扰和相同信道动态串扰的标准测试方法，当特定光信道信号切换到特定分支端口时，会发生这种串扰≥ 3） WSSs。

IEC 62343-5-2:2018 describes the measurement methods of dynamic crosstalk during port switching for 1 x N fixed-grid wavelength selective switches (WSSs). The objective of this document is to establish a standard test method for different-channel dynamic crosstalk and same-channel dynamic crosstalk that occur when a particular optical channel signal is switched to the specific branching port against a common port in ITU？T 50 GHz and 100 GHz fixed grid 1 x N (N ≥ 3) WSSs.
