Abstract

Multiplexor óptico pasivo de tipo "add-drop" para sistemas de telecomunicación basados en la transmisión de múltiples señales ópticas por medio de su multiplexación por división en longitud de onda (WDM). El dispositivo distingue entre señales transmitidas en conjuntos de uno o más canales ópticos situados en bandas separadas del espectro óptico. Incorpora al menos dos filtros ópticos (20, 30, 120, 130), un primer multiplexor WDM (50, 150) y un combinador (40, 140). El primer filtro (20, 120) y el segundo filtro (30, 130) están conectados ópticamente entre sí y también con el primer multiplexor WDM (50, 150). El combinador (40, 140) combina en una señal óptica de salida, un canal de a insertar con la señal óptica reflejada sin los al menos dos canales ópticos diferentes desviados por los filtros.
