  • Patent number: 6483803
    Abstract: A system and method for connecting traffic along a communications network is accomplished by rerouting traffic upon the detection of a fault condition along a primary connection path. Signals are divided into different wavelength regions labeled red and blue, respectively. The wavelength bands between transmit and receive channels are alternated between red and blue band regions and then combined, multiplexed or “bundled” together by a wideband wavelength division multiplexer in a single non wavelength specific transmission medium for connection to a single uni-directional Optical Cross Connect System (OCCS) port. Additionally, the receiving end of a single medium is connected to a wavelength division multiplexer which unbundles the combined red and blue band signals upon reception.
