Abstract
Disclosed herein is an optical cross-connect device including first wavelength demultiplexing sections each for demultiplexing WDM (wavelength division multiplexed) signal light into a plurality of optical signals, wavelength group generating sections each for receiving the optical signals from each first wavelength demultiplexing section to generate wavelength groups, first wavelength multiplexing sections each for receiving each wavelength group from each wavelength group generating section to output a WDM wavelength group, a routing section for routing the input WDM wavelength groups, second wavelength demultiplexing sections each for receiving each WDM wavelength group from the routing section to output a wavelength group having a plurality of wavelengths, wavelength converting sections each for performing wavelength conversion of each optical signal of the wavelength group output from each second wavelength demultiplexing section, and second wavelength multiplexing sections each for wavelength division multiplexing optical signals output from the wavelength converting sections. This device is suitable for construction of a large-scale optical network supporting an increase in …
