This part of IEC 61978 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 can be polarization sensitive.

This document establishes uniform requirements for the passive chromatic dispersion compensator.

IEC 61978-1 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. It is an International Standard.

This fourth edition cancels and replaces the third edition published in 2014. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) harmonization of terms and definitions with IEC TS 62627-09;

b) change of Clause 4 regarding requirements.
