METHOD AND DEVICE FOR PURE OPTICAL REGENERATION OF PHASE-MODULATED OPTICAL SIGNALS WITH REGARD TO PULSE SHAPE PULSE HEIGHT TIMING AND PHASE

摘要

The invention relates to a method and a device for pure optical regeneration of phase-modulated optical signals with regard to pulse shape pulse height timing and phase. The following steps are carried out: preparation of a phase-modulated optical signal for regeneration, introduction of the input signal to a timing recovery device (2) and to a phase/amplitude converter (1), in the timing recovery device (2), regeneration of the input signal with regard to pulse shape, pulse height and timing with loss of phase information for the input signal and with a creation of a regenerated clock signal, in the phase/amplitude converter (1), conversion of the phase modulation of the input signal into an amplitude modulation with generation of an amplitude-modulated data signal and modulation to the phase of the regenerated clock signal corresponding to the amplitude-modulated data signal in a phase modulator (3) with non-linear characteristics.
