Self-amplitude modulation in PSK coherent optical transmission systems

摘要: Self-amplitude modulation due to group velocity dispersion (chromatic of an optical fiber) in phase-shift keying (PSK) coherent transmission systems is presented. It may place a serious limitation on performance such by limiting the maximum distance attainable at given bit rate. The for any prescribed degree self-amplitude derived PSK systems. result shows that over which appreciable amplitude impressed phase-modulated signal considerably less than dispersion-limited intensity modulated direct detection
