Abstract

La présente invention concerne un appareil optique de démultiplexage en longueur d'onde destiné à démultiplexer un signal optique multiplexé possédant une pluralité de canaux occupant des bandes de longueurs d'ondes respectives. L'appareil comprend au moins un sélecteur (11, 12) de bande d'onde qui sélectionne des bandes de longueurs d'ondes correspondant à des canaux non adjacents, les bandes de longueurs d'ondes sélectionnées étant acheminées vers un démultiplexeur (30, 31) de réseau associé qui sort les bandes de longueur d'onde sélectionnées sous forme d'un réseau parallèle de canaux.
