The method involves determining a quality parameter (Q, BER) at the end of the transmission path for each channel, producing a quality parameter spectrum, re-selecting different Raman gain profiles for at least one amplifier (RV1,..) to equalize and optimize the quality parameter for the channels depending on the spectrum so that the corresponding gain profiles are set by re-regulation of the pump currents of the pump sources. AN Independent claim is also included for the following: an optical transmission system.
