ABSTRACT:
A fiber optic communication system comprising:an optical signal source adapted to produce a frequency modulated signal; andan optical spectrum reshaper (OSR) adapted to convert the frequency modulated signal into a substantially amplitude modulated signal, wherein the optical spectrum reshaper is adapted to compensate for at least a portion of a dispersion in a transmission fiber;and further including a transmission fiber coupled to the optical source, a receiver and a decision circuit coupled to the transmission fiber.
