A device for regenerating an optical signal, the use of such a device, and an installation including such a device

摘要

The device has a differential phase shift keying demodulator (14) for converting a signal carrying phase modulated information into two secondary signals carrying amplitude modulated information. An amplitude regeneration module (16) regenerates the secondary signals. A differential phase shift keying demodulator (18) converts the regenerated signals into a signal carrying the same phase modulated information. - Independent claims are also included for the following: - (A) an optical transmission device having an optical fiber and optical signal regeneration device - (B) a utilization of the device for the regeneration of the optical signal.
