Abstract
L'invention concerne une architecture optique haute performance pour le multiplexage/démultiplexage de canaux dans des systèmes optiques à haute efficacité spectrale. En règle générale, les architectures rentrent dans deux catégories principales: groupes de longueur d'onde, et canaux. Dans le premier cas, on utilise une caractéristique associée à des groupes de canaux multiplexés, pour la séparation de ces groupes par rapport à un signal optique de plusieurs groupes de multiplexage. En modes de réalisation préférés, la catégorie canaux est avantageuse car interchangeable (sans spécificité de longueur d'onde entre groupes), ce qui permet de réduire les coûts et la complexité, et on ajoute des gammes spectrales libres judicieusement choisies pour assurer les fonctions de filtrage optique répétitif sur des groupes de canaux (à savoir, sous-ensembles de canaux dans chaque bande de longueurs d'onde), de sorte que la catégorie canaux interchangeable fonctionne de la même manière dans chaque groupe. Chaque catégorie canaux est donc interchangeable. Il est intéressant de noter que la compensation de distorsion peut s'effectuer par groupe.
