    • The invention relates to a regenerator using optical phase modulation in an optical fiber transmission system using soliton signals. According to the invention, the soliton signal is modulated by a clock in a modulator which is itself contained in an interferometer; the output signal from the interferometer has intensity that is representative of the phase difference between the clock and the soliton signal, and is therefore suitable for use in controlling the phase of the clock. In an embodiment, the interferometer is a Sagnac interferometer constituted by a non-linear optical loop mirror, and the modulation is distributed phase modulation in the transmission fiber. This enables the clock to be synchronized in simple manner.
