IEC 61978-1 Ed. 4.0 b:2024 PDF
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;
