Abstract
L'invention concerne un filtre optique comprenant deux bandes de transmission. La première bande est relativement étroite (environ 1 nm) et présente une longueur d'onde d'environ 1550 nm, alors que la seconde bande est relativement large (plus de 50 nm), de manière à transmettre des longueurs d'onde variant entre 1300 et 1400 nm. Par conséquent, le filtre peut être utilisé dans des systèmes de communication de multiplexage en longueur d'onde pour sélectionner simultanément un canal de charge utile présentant une longueur d'onde d'environ 1550 nm et un canal de service de 1310 nm.
