ABSTRACT:
In order to insert a regenerator into a wavelength cross-connect equipment, there is provided at least one port that demultiplexes one wavelength among the wavelength multiplexed signals that are input to a wavelength selective switch. An output of the port that demultiplexes one wavelength is input to the regenerator, and an output of the regenerator is again input to the WSS. The wavelength output from the regenerator is converted into another wavelength different from the wavelength that is input to the regenerator and can be processed by the WSS in advance. The output from the regenerator is input to the WSS through an optical coupler or another input port of the WSS.
