摘要：
A method for transmitting a signal and a fiber optic system comprising: a frequency modulated source; an optical transmission fiber positioned to receive the output of the frequency modulated source; an optical filter positioned to receive the output of the optical transmission fiber; and an optical receiver positioned to receive the output of the optical filter; characterized in that: an optical spectrum reshaper is positioned between the frequency modulated source and the optical transmission fiber; and wherein the optical filter is a narrow band pass filter relative to the bit rate of the transmitted signal; and further wherein the frequency excursion of the frequency modulated source is between 20% and 120% of the bit rate frequency.
