FIBER OPTIC COMMUNICATION SYSTEM AND METHOD FOR TRANSMITTING A SIGNAL

摘要

The invention relates to a fiber optic communication system comprising an optical signal source adapted to receive a binary base signal having a bit period T, and generate a first signal, wherein the first signal is frequency modulated. According to the invention, the system comprises an optical spectrum reshaper (OSR) adapted to reshape the first signal into a second signal, wherein the second signal has an amplitude modulated component and a frequency modulated component, wherein the optical signal source comprises a laser, and wherein the frequency modulation is generated by modulating a phase of a laser cavity of the laser.
