Abstract :
A simple method for optimising the launch power to a single or multispan optical transmission system using a new fibre nonlinearity monitor is described. Inserting a subcarrier into the data-band, it was possible to correlate the BER performance of the 10 Gbit/s signal to the power of the subcarrier.
