Fibre optic interconnecting devices and passive components - Fibre optic fixed filters - Generic specification
IEC 61977:2020 is available as IEC 61977:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61977:2020 applies to the family of fibre optic filters. These components have all of the following general features: - they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port; - they modify the spectral intensity distribution in order to select some wavelengths and inhibit others; - they are fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned; - they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; the ports are optical fibre or optical fibre connectors; - they differ according to their characteristics. They can be divided into the following categories: - short-wave pass (only wavelengths lower than or equal to a specified value are passed); - long-wave pass (only wavelengths greater than or equal to a specified value are passed); - band-pass (only an optical window is allowed); - notch (only an optical window is inhibited); - gain flattening (compensating the spectral profile of the device). It is also possible to have a combination of the above categories. This document provides the generic information including terminology of IEC 61753-04x series documents. Published IEC 61753-04x series documents are listed in the Bibliography. This document establishes uniform requirements for optical, mechanical and environmental properties. This fourth edition cancels and replaces the third edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - change of the title and the scope for the limitation to fibre optic fixed filters; - addition of new terms and definitions reflecting new title; - removal of terms and definitions duplicated in IEC TS 62627-09; - harmonization of the vertical axis of Figures 1 to 5; - restructuration of Clause 4 reflecting the latest technical and market situation.

IEC 61977:2020 est disponible sous forme de IEC 61977:2020 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.IEC 61977:2020 s’applique à la famille des filtres fibroniques. Ces composants possèdent l’ensemble des caractéristiques générales suivantes: - ils sont passifs du fait qu’ils ne contiennent aucun élément optoélectronique ou autres éléments transducteurs susceptibles de traiter le signal optique injecté dans le port d’entrée; - ils modifient la distribution d’intensité spectrale afin de sélectionner certaines longueurs d’onde et en interdire d’autres; - ils sont fixes, c’est-à-dire que la modification de la distribution de l’intensité spectrale est constante et ne peut donc être accordée; - ils comportent des ports d’entrée et de sortie ou un port commun (comportant à la fois les fonctions d’entrée et de sortie) pour la transmission de la puissance optique; les ports sont une fibre optique ou des connecteurs à fibres optiques; - ils diffèrent en fonction de leurs caractéristiques. Ils peuvent être répartis dans les catégories suivantes: - passe-bas (seules les longueurs d’onde inférieures ou égales à une valeur spécifiée sont transmises); - passe-haut (seules les longueurs d’onde supérieures ou égales à une valeur spécifiée sont transmises); - passe-bande (seule une fenêtre optique est autorisée); - coupe-bande (seule une fenêtre optique est interdite); - aplanissement de gain (compensation du profil spectral du dispositif). Une combinaison des catégories ci-dessus est également possible. Le présent document fournit des informations génériques et notamment la terminologie des documents de la série IEC 61753-04x. Les documents publiés de la série IEC 61753-04x sont indiqués dans la Bibliographie.AnchorAnchorAnchorAnchorAnchor Le présent document établit des exigences uniformes pour les propriétés optiques, mécaniques et environnementales. Cette quatrième édition annule et remplace la troisième édition parue en 2015 dont elle constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - modification du titre et du domaine d'application pour limiter le présent document aux filtres fibroniques fixes; - introduction de nouveaux termes et définitions pour refléter le nouveau titre; - suppression des termes et définitions présents dans l'IEC TS 62627-09; - harmonisation de l'axe vertical des Figures 1 à 5; - restructuration de l'Article 4 pour refléter les dernières situations techniques et du marché.
