The waveform deterioration detection range is broadened and multi bit rates can be handled. A chromatic dispersion compensator (or polarization mode dispersion compensator) (102) receives a waveform-deteriorated NRZ optical signal entered through an input fiber (101) and compensates it. On the other...http://www.google.de/patents/US7813655?utm_source=gb-gplus-sharePatent US7813655 - Signal waveform deterioration compensator
