Abstract

La présente invention concerne un noeud (52-1) de réseau de communication à fibres optiques (50) qui comprend un premier dispositif (182, 186) servant à convertir en un premier signal électrique un premier signal optique à une première fréquence porté par le réseau (50), un deuxième dispositif (188) servant à démoduler du premier signal électrique une première information modulée sur le premier signal optique, un troisième dispositif (198) servant à moduler la deuxième information sur un deuxième signal électrique, un quatrième dispositif (210) servant à convertir la deuxième information modulée sur le deuxième signal électrique en un deuxième signal optique à la première fréquence, et un cinquième dispositif (66, 204-1) servant à émettre un troisième signal optique à une seconde fréquence, la troisième information étant modulée sur celui-ci. Le noeud (52-1) comprend également un sixième dispositif (206, 208) destiné à multiplexer le deuxième et le troisième signal optique sur le réseau (50).
