Abstract
An example system includes an optical modulator and a multiplexing controller. The modulator includes a data bus for receiving at least one data signal, a plurality of multiplexers and a plurality of modulating segments. Each multiplexer is coupled to the data bus to receive at least one data signal and to output a multiplexed signal. Each modulating segment may receive the multiplexed signal from one of the plurality of multiplexers and modulate the multiplexed signal using an optical input. The multiplexing controller may be in communication with the plurality of multiplexers and may configure each of the plurality of multiplexers in accordance with a selected modulation type.
