IEC 61978-1:2024 is available as IEC 61978-1:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61978-1:2024 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. 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.
