Abstract
A method for providing multi-wavelength switching. The method comprising receiving a plurality of signals through at least one input port, and separating the plurality of said signals into at least one wavelength signal set based on wavelengths, wherein a first wavelength signal set of said at least one wavelength signal sets corresponds to a first wavelength. The method further comprises providing a plurality of output lanes to at least one output port, and determining if two signals from said first wavelength signal set traveling on said first wavelength are scheduled output from an output port during an overlapping time period through said plurality of output lanes. The method further comprises determining if one of said plurality of output lanes is available during said overlapping time period when said two signals are schedule for said output port during the overlapping time period, wherein a first signal of said two signals is routed for output on an available lane if one of said plurality of output lanes of said output port is available.
