IEC 62074-1:2014

Fibre optic interconnecting devices and passive components - Fibre optic WDM devices - Part 1: Generic specification

IEC 62074-1:2014 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 may use temperature control only to stabilize the device characteristics;
- they exclude any optical switching functions;
- they have three or more ports for the entry and/or exit of optical power, 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 standard establishes uniform requirements for the following: optical, mechanical and environmental properties. This second edition cancels and replaces the first edition, published in 2009, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- substantial updating to the definitions;
- the addition of informative Annexes C to G, giving examples of technical information concerning WDM devices. Keywords: fibre optic wavelength division multiplexing, WDM, requirements for optical, mechanical and environmental properties

Dispositifs d'interconnexion et composants passifs à fibres optiques - Dispositifs WDM à fibres optiques - Partie 1: Spécification générique

L'IEC 62074-1:2014 s'applique aux dispositifs de multiplexage par répartition en longueur d'onde (WDM) à fibres optiques, dont les caractéristiques générales sont les 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 et/ou la sortie de la puissance optique 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 à fibres optiques. La présente norme spécifie les exigences uniformes pour: les propriétés optiques, mécaniques et environnementales. Cette deuxième édition annule et remplace la première édition publiée en 2009; elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- mise à jour significative des définitions;
- ajout des Annexes informatives C à G présentant des exemples d'informations techniques relatives aux dispositifs WDM. Mots clés: dispositifs de multiplexage par répartition en longueur d'onde (WDM) à fibres optiques, exigence pour les propriétés optiques, mécaniques et environnementales
