Abstract
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.
