Synchronous optical regenerator using intensity modulation and phase modulation by the crossed kerr effect

A regenerator for a wavelength division multiplex optical transmission system including:

• a demultiplexer supplying demultiplexed channels at its output,
• for each demultiplexed channel, a multiplexer coupling continuous light with the signals of said channel, an intensity modulator modulating said signals of said channel and said continuous light and a Kerr fiber phase modulating said transmitted signals with said intensity-modulated continuous light by crossed phase modulation, and
• a multiplexer receiving said phase-modulated signals of each channel and supplying a multiplexed signal.
