IEC 60876-1 Ed. 5.0 b – Fibre optic interconnecting devices and passive components – Fibre optic spatial switches – Part 1: Generic specification

IEC 60876-1:2014 applies to fibre optic switches possessing all of the following general features:
– they are passive in that they contain no optoelectronic or other transducing elements;
– they have one or more ports for the transmission of optical power and two or more states in which power may be routed or blocked between these ports;
– the ports are optical fibres or fibre optic connectors. This fifth edition cancels and replaces the fourth edition that was published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– addition of definitions for the terms for “normally-on;
– “normally-off” and “crosstalk”;
– addition of a new Annex E. Keywords: fibre optic switches, transmission of optical power, fibre optic connectors
