Abstract

A fiber optic communication system comprising: an optical signal source adapted to receive a base binary signal and produce a first frequency modulated signal, and an optical spectrum reshaper or an amplitude modulator adapted to reshape the first signal into a second amplitude and frequency modulated; characterized in that: 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. In another form of the present invention, there is provided a method for transmitting a base signal, comprising: using the base signal to produce a frequency modulated signal; and providing an amplitude modulator for receiving the frequency modulated signal and for generating an amplitude and frequency modulated signal.
