Abstract
An optical data generator for generating a return-to-zero optical data stream. The optical data generator includes a single optical modulator for receiving an input optical signal, an electrical data generator for generating a return-to-zero electrical data stream, and a driver amplifier for receiving the return-to-zero electrical data stream and providing a modulation signal representing the return-to-zero electrical data stream to the optical modulator. The optical modulator is configured to modulate the modulation signal onto the input optical signal to generate a return-to-zero optical data stream at an output port of the optical data generator.
