IEC 61978-1 (2014-05)

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
