Paper Abstract

An important advantage of coherent lightwave systems is that they can offer access to the vast transmission capacity of single mode fiber by the use of optical frequency division multiplexing.1 The potential of multichannel coherent fiber optic communication systems is increased significantly when the systems employ optical amplifiers as repeaters and/or power boosters.2 One of the main issues concerning such systems is the determination of optimum channel spacing, which would allow maximum channel packing density without system degradation.3 This paper reviews the technical progress and the performance of multichannel coherent lightwave systems. Main technical issues in such systems are first identified4-6 and the mechanism and sources of interchannel crosstalk are discussed.7,8 Then bit-error-rate performance and crosstalk penalty in a multichannel ASK heterodyne system are described. The primary focus is on the laser linewidth effect on channel spacing.9 Some experimental results are compared with the predictions of a theoretical mode1.7,10 This is followed by a discussion on the crosstalk and channel spacing in the presence of optical amplifiers.11-14 Finally, technical areas and issues for further work are identified.
