  • Optical switching system
    Patent number: 6665463
    Abstract: The present invention relates to an optical switching system that includes two channel switchers. Each switcher includes an optical switch, a wavelength converter, and a multiplexer. Selectors provide and receive optical WDM signals to and from the two channel switchers in alternating fashion such that the latency time of the optical switching system is minimized to the latency time of a selector. The optical switch of an inactive switcher is configured while the active switcher converts a WDM signal.
    Type: Grant
