Abstract:
1. An optical cross-connect apparatus comprising: a plurality of switch units connected to each other via a plurality of input ports and a plurality of output ports such that wavelength-multiplexed signals are input and output between two or more lines, and each optical signal with a respective wavelength included in a wavelength-multiplexed signal is transmitted from a first line of the lines to a second line of the lines or from the second line to the first line; a storage unit configured to store a setting table in which output port information and corresponding input port information are associated together and registered for each optical signal such that the output port information identifies a specific output port, in the plurality of output ports, that outputs the optical signal and the input port information identifies a specific input port, in the plurality of input ports, that inputs the optical signal; a setting processor configured to set each switch unit in the plurality of switch units according to the setting table so as to set a wavelength for each optical signal that is input via the input ports or output via the output ports; and an update processor configured to update the content of the setting table in response to information of external input.
