Abstract :
The first observation of four-wave mixing in a distributed erbium-doped fibre amplifier is reported. Optical pumping of a 16 km length of fibre to achieve lossless transmission sustains the nonlinear interaction at an almost constant level, making optimum use of the long interaction length available in fibre waveguides. BER data on the effects of four-wave mixing in a multichannel coherent transmission system are reported.
