Abstract
Official abstract text for this publication.
An optical communication device includes an optical switch that outputs an optical signal input from one of a plurality of transmission lines to another transmission line among the plurality of transmission lines, a communication unit that communicates with a subscriber device without using the optical switch, a wavelength controller that sets a wavelength to be used for communication of an optical signal by communicating with the subscriber device via the communication unit, and an optical switch controller that controls the optical switch such that an optical signal transmitted from the subscriber device is input from a port to which the subscriber device is connected and output to another port connected to a transmission line corresponding to a transfer destination on a path to a communication destination.
First claim
Opening claim text (preview).
1 . An optical communication device comprising: an optical switch that outputs an optical signal input from one of a plurality of transmission lines to another transmission line among the plurality of transmission lines; a communication unit that communicates with a subscriber device without using the optical switch; a wavelength controller that sets a wavelength to be used for communication of an optical signal by communicating with the subscriber device via the communication unit; and an optical switch controller that controls the optical switch such that an optical signal transmitted from the subscriber device is input from a port to which the subscriber device is connected and output to another port connected to a transmission line corresponding to a transfer destination on a path to a communication destination. 2 . An optical communication system comprising: a plurality of subscriber devices; and the optical communication device according to claim 1 . 3 . An optical communication method performed by an optical communication device including an optical switch, the method comprising: communicating with a subscriber device without using the optical switch; setting, for the subscriber device, a wavelength to be used for communication of an optical signal through communication not using the optical switch; causing the optical switch to output an optical signal input from one of a plurality of transmission lines to another transmission line among the plurality of transmission lines; and causing an optical switch controller to control the optical switch such that an optical signal transmitted from the subscriber device is input from a port to which the subscriber device is connected and output to another port connected to a transmission line corresponding to a transfer destination on a path to a communication destination.
