摘要： In one embodiment of the invention a dispersion compensator is provided for use in a dense wavelength division multiplexed optical communication system. The dispersion compensator comprises a periodic-group-delay dispersion compensation module which provides a portion of the dispersion compensation for a dispersion managed span of the optical communication system. A remaining portion of the dispersion compensation for the dispersion managed span is provided by dispersion compensating fiber. The portions of the dispersion compensation provided by each of the periodic-group-delay dispersion compensation module and the dispersion compensating fiber is selected such that the collision-induced timing jitter is reduced.

摘要： An optical duobinary transmission system and method are provided for transmitting optical duobinary signals across an optical transmission link having residual dispersion. The system includes a transmitter having a low bandwidth modulator, adapted to provide filtering for low pass filtered duobinary transmission. The transmission link is designed such that the residual dispersion of the transmission link substantially compensates for signal distortion from the transmitter.
