Patent ID: 7751710

Claim:
A photonic cross-connector system comprising: an optical coupler branching an input optical signal into a plurality of paths; a WSS (wavelength selective switch) extracting at least one wavelength signal from the input optical signal and outputting the extracted wavelength signal to at least one port; a WDM (wavelength division multiplexing) multi-casting apparatus simultaneously copying and regenerating the input optical signal into different wavelengths and changing modulation methods of the input optical signal into different types of modulation methods; an optical transmitter and/or receiver branching and coupling the input optical signal; and a control system controlling the optical coupler, the WSS, the WDM multicasting apparatus, and the optical transmitter and/or receiver wherein the WSS is divided into a branching WSS and a coupling WSS, and the WDM multicasting apparatus is disposed between the optical coupler and the branching WSS.
