DEVICE AND METHOD FOR COMPENSATING POLARIZATION MODE DISPERSION IN AN OPTICAL COMMUNICATION SYSTEM |
摘要 |
An optical communication system comprising: a transmitter for sending a digital signal, an optical transmission line, a receiver comprising a modulation and dispersion device, the said modulation and dispersion device comprising: a) a modulation device for modulating the phase of the said digital optical signal by a modulation having: a1) a predetermined modulation frequency, a2) a periodic variation in time, a3) a maximum amplitude of said periodic variation; b) a chromatic dispersion element providing an anomalous dispersion when the said periodic variation has a positive modulation amplitude and a normal dispersion when the said periodic variation has a negative modulation amplitude. |
