Abstract
L'invention concerne un dispositif (44; 45) de multiplexage optique, permettant le multiplexage en longueurs d'ondes d'une pluralité (M) de canaux (16) optiques, M étant >= 8. Ce dispositif (44; 45) de multiplexage comprend N points (208, 208') d'entrée, N étant $me(G)M, et un point (233; 254) de sortie, et au moins trois coupleurs (202, 202', 205, 205', 207, 207', 206, 206', 213, 213', 217, 217', 225, 225', 231) optiques présentant des atténuations intrinsèques prédéterminées et reliés les uns aux autres selon une topologie arborescente, cette topologie comprenant N entrées et une sortie correspondant audits N points (208, 208') d'entrée et un point (233; 254) de sortie. Ce dispositif est caractérisé en ce que a) l'atténuation intrinsèque de chacun des coupleurs (202, 202', 205, 205', 207, 207', 206, 206', 213, 213', 217, 217', 225, 225', 231) optiques est présélectionné, et b) ces coupleurs (202, 202', 205, 205', 207, 207', 206, 206', 213, 213', 217, 217', 225, 225', 231) optiques sont disposés selon ladite topologie arborescente de telle manière qu'en passant à travers le dispositif (44; 45) de multiplexage, au moins deux de la pluralité M de canaux (16) optiques présentent une atténuation différente l'un de l'autre. Lorsque le dispositif est intégré à un système de transmission MLO, p. ex. un système utilisant des amplificateurs de fibre en ligne, ces différences d'atténuation des canaux de la ligne de transmission peuvent être égalisées.
