Abstract
(EN)  The present invention provides an optical relay device, etc., capable of outputting control signal light without being provided with a light source for the control signal light and also capable of flexibly managing and changing the wavelength of the control signal light in accordance with a network state. This optical relay device is provided with: an optical reception means for receiving a wavelength-multiplexed optical signal; a control means for designating a first wavelength and outputting notification information; and a processing means for selecting an optical signal of the first wavelength from the received wavelength-multiplexed optical signal, applying intensity modulation corresponding to the notification information to the selected signal, restoring the intensity-modulated optical signal to a wavelength-multiplexed optical signal, and outputting the restored signal.
(FR)  La présente invention concerne un dispositif de relais optique, etc., apte à délivrer en sortie une lumière de signal de commande sans être pourvu d'une source de lumière pour la lumière de signal de commande, et également apte à gérer et changer de façon flexible la longueur d'onde de la lumière de signal de commande en fonction d'un état de réseau. Ce dispositif de relais optique est pourvu : d'un moyen de réception optique pour recevoir un signal optique multiplexé en longueur d'onde ; d'un moyen de commande pour désigner une première longueur d'onde et délivrer en sortie des informations de notification ; et d'un moyen de traitement pour sélectionner un signal optique de la première longueur d'onde dans le signal optique multiplexé en longueur d'onde reçu, appliquer au signal sélectionné une modulation d'intensité correspondant aux informations de notification, restaurer le signal optique à intensité modulée en un signal optique multiplexé en longueur d'onde, et délivrer en sortie le signal restauré.
