Abstract:
1. An optical regenerator for a differential phase shift keyed data signal (DS), whose input side comprises a unit for bit-by-bit level control (PN, PN 1 ) in which the same amplitude is set for each symbol of the differential phase shift keyed data signal (DS), in that the unit for level control (PN) is followed by a splitter (SP) having two outputs, in which the data signal (DS) whose amplitude has been set is split into a first data signal (DS in that the first output of the splitter is connected to a phase error ascertainment unit (EP) in which a phase error in the supplied first data signal (DS in that the output of the phase error ascertainment unit (EP) is connected to a first input of a unit for correcting the phase errors (KP), the second input of which is connected to the second output of the splitter (SP), so that the unit for correcting the phase errors (KP) corrects the phase of the second data signal (DS
