Abstract:
1. A wavelength division multiplexing (WDM) transmitter system, comprising: a plurality of optical transmitters; a filter array including a plurality of filters, the filters each connectable to an associated optical transmitter and having a disparate center frequency and a spectrum width dynamically adjustable to correspond to a bandwidth of an optical signal generated by the associated optical transmitter; a combiner operable to combine into a wavelength division multiplexing (WDM) signal a plurality of the optical signals generated by the optical transmitters and passing through the filters of the filter array; a plurality of transponders, the transponders each connectable to an associated optical transmitter and operable to adjust a center frequency of a received optical signal to generate a frequency adjusted optical signal and to provide the frequency adjusted optical signal to a connected filter of the filter array; and wherein each of the transponders is directly connected to the associated optical transmitter, further comprising a cross-connect operable to connect at least a subset of the transponders to at least a subset of the filters of the filter array.
