Abstract
An optical communication system which has an optical signal source adapted to receive a base binary signal and produce a first signal, said first signal being frequency modulated; andan optical spectrum reshaper adapted to reshape the first signal into a second signal, said second signal being amplitude modulated and frequency modulated in which the frequency characteristics of said first signal, and the optical characteristics of said optical spectrum reshaper, being such that the frequency characteristics of said second signal are configured so as to increase the tolerance of the second signal to dispersion in a transmission fiber.
