IEC 61000-3-50: 2025 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.
This second edition cancels and replaces the first edition published in 2013. This edition constitutes a technical revision.  This edition includes the following significant technical changes with respect to the previous edition:
a) revising structure of the document.
