Practical coherent optical fibre transmission systems will have to be insensitive to the random polarisation changes introduced by the birefringent transmission medium and to date the techniques considered for achieving this are polarisation tracking receivers [1] and polarisation diversity receivers [2]. In this paper an alternative technique is reported which achieves diversity by scrambling the polarisation at the transmitter subsequent to modulating the optical carrier. The advantages of this technique are that for wavelength multiplexed systems one scrambler per transmission fibre is all that is required and because the receiver design is kept simple it is particularly suited to local network applications.
