Fibre optic interconnecting devices and passive components - Fibre optic WDM devices - Part 1: Generic specification
IEC 62074-1: 2025 applies to fibre optic wavelength division multiplexing (WDM) devices. These have all of the following general features: - they are passive, in that they contain no optoelectronic or other transducing elements; however they can use temperature control only to stabilize the device characteristics; they exclude any optical switching functions; - they have three or more ports for either the entry or exit of optical power, or both, and share optical power among these ports in a predetermined fashion depending on the wavelength; - the ports are optical fibres, or optical fibre connectors. This document establishes uniform requirements for the following: - optical, mechanical and environmental properties. This third edition cancels and replaces the second 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) simplified classification, documentation and standardization system in Clause 4, and moving interface style to Annex H.

IEC 62074-1: 2025 s’applique aux dispositifs fibroniques de multiplexage par répartition en longueur d’onde (MRL). Ceux-ci présentent l’ensemble des caractéristiques générales suivantes: - ils sont passifs, en ce qu’ils ne contiennent aucun élément optoélectronique ni autre élément de transduction; mais ils peuvent utiliser une commande de température uniquement dans le but de stabiliser les caractéristiques des dispositifs; ils excluent toute fonction de commutation optique; - ils possèdent au moins trois ports pour l’entrée ou la sortie de la puissance optique, ou les deux, et partagent la puissance optique entre ces ports d’une façon prédéterminée en fonction de la longueur d’onde; - les ports sont des fibres optiques ou des connecteurs optiques. Le présent document spécifie les exigences uniformes pour: - les propriétés optiques, mécaniques et environnementales. Cette troisième édition annule et remplace la deuxième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) harmonisation des termes et définitions avec ceux de l’IEC TS 62627-09,b) simplification du système de classification, de documentation et de normalisation à l’Article 4 et déplacement du style d’interface à l’Annexe H.
