Fibre optic interconnecting devices and passive components - Fibre optic passive chromatic dispersion compensators - Part 1: Generic specification

IEC 61978-1:2014 applies to fibre optic passive chromatic dispersion compensators, all exhibiting the following features: - they are optically passive; - they have an optical input and an optical output for transmitting optical power; - the ports are optical fibres or optical fibre connectors; - they are wavelength sensitive; - they may be polarization sensitive. This standard establishes uniform requirements for the passive chromatic dispersion compensator. This third edition cancels and replaces the second edition, published in 2009, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - introduction of new terms and definitions; - revision of classifications; - addition of Annex E. Keywords: fibre optic passive chromatic dispersion compensators
