A detector outputs a detection signal indicating amplitude variation of an input frequency-multiplexed signal. An amplitude controller adjusts the amplitude of the frequency-multiplexed signal by referring to the detection signal. A modulator modulates the amplitude-adjusted frequency-multiplexed signal...http://www.google.fr/patents/US7110672?utm_source=gb-gplus-shareBrevet US7110672 - Optical transmission system for frequency-multiplexed signal
