Frequency stabilized 622-Mb/s 16-channel optical FDM system and its performance in 1.3/1.55-/spl mu/m zero-dispersion fiber transmission

A study has been conducted on a densely multiplexed 16-channel optical FDM system. A transmitter contains 16 two-section MQW DFB-LD's and a star coupler. An automatic optical multi-frequency controller stabilizes each LD of 10 GHz spacing within /spl plusmn/100-MHz accuracy. A receiver consists of heterodyne-delay-demodulators using a polarization diversity. Any desired channel can be tuned by a novel frequency discriminator with no insensitive frequency region. The system has successfully transmitted 622 Mb/s-16-channel HDTV signals through 110 km long 1.3 /spl mu/m-zero-dispersion fiber. We have also studied error rate degradation due to four-wave mixing in a 1.55 /spl mu/m-dispersion-shifted-fiber. Experimental results have revealed the allowable total input power to be +2 dBm for dispersion-shifted fibers. >
