Patent attributes
Technology for a contentionless N×M wavelength cross connect (WXC) device is disclosed herein. The WXC device includes multiple input and output wavelength dispersive elements and a cross connect assembly. The cross connect assembly includes multiple rows of incoming ports. For each individual wavelength of different wavelengths, split optical beams of the individual wavelength from the input wavelength dispersive elements reach a row of incoming ports corresponding to the individual wavelength. The cross connect assembly further includes transmissive active switching elements and multiple rows of outgoing ports. The transmissive active switching elements configured to dynamically establish at least one optical path between an incoming port within the row of incoming ports corresponding to the individual wavelength and an outgoing port within a row of output ports corresponding to the individual wavelength.
