Device for the regeneration of a pulse train and device for the recovery of a to a modulated pulse train synchronized periodic signal

摘要

The device for the return in the form of a set of optical pulses, comprises a modulator (11) electroabsorbent on which the train of pulses is sent to be resynchronized and put back in the form; a generator (12) of the periodic signal in phase and frequency, which delivers to the modulator (11) a periodic signal which controls the voltage at the modulator (11); the control means (13) which controls the generator 12 in phase and frequency, so that the average of the & br / (see appended drawing in bopi) & br / & & br / in its state and that it receives an optical pulse, or minimal. & br / & this device can also be used for the recovery of a periodic signal synchronized on a train of pulses modulated optical. & br / application to the telecommunication long distance transmission of the soliton pulses by optical fibers.
