Fibre optic interconnecting devices and passive components - Fibre optic passive chromatic dispersion compensators - Part 1: Generic specification
IEC 61978-1:2009 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; - they are wavelength sensitive; - they may be polarization sensitive. This standard establishes uniform requirements for the passive chromatic dispersion compensator. Changes from the previous edition of this standard are to reconsider the requirements.

La CEI 61978-1:2009 s'applique aux compensateurs de dispersion chromatique passifs à fibres optiques présentant les caractéristiques suivantes: - ils sont passifs au niveau optique; - ils possèdent une entrée optique et une sortie optique pour la transmission de la puissance optique; - les portes sont des fibrres optiques ou des connecteurs optiques; - ils sont sensibles aux longueurs d'onde; - ils peuvent être sensibles à la polarisation. La présente norme établit des exigences uniformes sur les compensateurs de dispersion chromatique passifs. Les changements par rapport à la première édition de cette norme consistent en la reconsidération des exigences.
