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
A fiber optic communication system, comprising: an optical signal source adapted to produce a frequency modulated signal; and an optical spectrum reshaper adapted to receive the frequency modulated signal and output a substantially amplitude modulated signal; wherein the optical spectr
