ABSTRACT:
In an optical transmission system in which a plurality of optical signal channels is multiplexed before transmission along a common optical path to a receiver, each channel is produced by means of a respective multimode injection laser, the overall cavity length of each laser being arranged to provide a multimode spectral output with a respective intermode spacing which differs from that provided by the other lasers for channel discrimination purposes. Comb filters are employed for demutliplexing.
