Title :
Effect of intermodulation in multichannel optical heterodyne systems

Abstract :
It is shown that large numbers of optical heterodyne channels may be frequency multiplexed over a single-mode optical fibre without the intermodulation byproducts of the photodetection process becoming a problem, provided the channels are spaced at five times their optical bandwidth, or greater.
