Reed-Solomon coded FSK SCM system with distributing LO in local loop in the presence of laser phase noise

In coherent optical subcarrier multiplexing systems, the performance degradation of the system due to the phase noise of lasers restricts the maximum numbers of stations and channels that the system can serve. The effects are analyzed in terms of carrier-to-noise ratio penalty. The effects of Reed-Solomon coding are also analyzed. It is shown that the numbers of channels and stations can be increased greatly by coding.<
