Abstract:
(EN) An optical add-drop multiplexer, which relates to the technical field of photoelectricity and can reduce the processing difficulty by using a large-size Bragg grating. The optical add-drop multiplexer comprises a lower wave signal separator (11) and a lower wave signal reflector (12). The lower wave signal separator (11) is connected to a main input end and a lower wave end, the lower wave signal separator (11) is connected to the lower wave signal reflector (12), and the lower wave signal reflector (12) is connected to a main output end.
(FR) La présente invention concerne un multiplexeur d’insertion-extraction optique, qui concerne le domaine technique de la photoélectricité et peut réduire la difficulté de traitement au moyen d’un réseau de Bragg de grande taille. Le multiplexeur d’insertion-extraction optique comprend un séparateur de signal d’onde inférieur (11) et un réflecteur de signal d’onde inférieur (12). Le séparateur de signal d’onde inférieur (11) est connecté à une extrémité d’entrée principale et à une extrémité d’onde inférieure, le séparateur de signal d’onde inférieur (11) est connecté au réflecteur de signal d’onde inférieur (12), et le réflecteur de signal d’onde inférieur (12) est connecté à une extrémité de sortie principale.
