Abstract
An optical transmission system comprises an electrical source and an electrical-to-optical converter. The electrical source is adapted to provide an electrical signal at an output thereof. The electrical-to-optical converter has an input coupled to the output of the electrical source and is operative to convert the electrical signal to a corresponding output optical signal. The electrical source comprises a pre-emphasis circuit or other electrical signal equalization circuitry configurable to control a waveform of the electrical signal so as to produce a desired level of jitter in the output optical signal.
