Abstract

Dans un multiplexeur optique d'insertion-extraction, un module de sélection de longueur d'onde accordable sépare sélectivement un ou plusieurs canaux des canaux à multiplexage par répartition en longueur d'onde reçus par le multiplexeur. Tandis que le ou les canaux séparés sont extraits par le multiplexeur, les autres canaux passent dans le multiplexeur et sont couplés à une fibre. Avant le couplage des canaux à la fibre, ceux-ci sont transmis à un module de conversion de longueur d'onde où ils sont multiplexés par un canal ajouté localement qui a été converti en une longueur d'onde non présente parmi les canaux passés dans le multiplexeur. Pour une plus grande flexibilité, il est possible de faire varier la longueur d'onde spécifique du canal converti en accordant le module de conversion de longueur d'onde.
