Abstract: PURPOSE: A method and an apparatus for reducing degradation of a system due to polarization effect are provided to obtain receiving sensitivity gain without causing attenuation of strength of an optical signal. CONSTITUTION: In order to remove mutual interference between bits generated due to polarization mode dispersion, an automatic polarization controller(100) makes a signal light Ax(Bx) coming from a transmitter incident at a slow polarization axis of an optical transmission line and Ay(By) incident at a fast polarization axis. When polarization mode dispersion is undergone on the optical transmission line, Ax(Bx) and Ay(By) overlap to convert an NRZ(Non Return to Zero) signal to an RZ(Return to Zero) signal. By doing that, the mutual interference between bits due to the polarization mode dispersion can be evaded and since the NRZ signal is converted into the RZ signal, receive sensitivity can be rather enhanced in case of undergoing the polarization mode dispersion. After passing through the optical line(110), a portion of the optical signal is split by an optical tap(120) and then monitored by a monitor(130). The monitored data is transferred to a controller(150) through a control channel(140), and the automatic polarization controller(100) is controlled to be fed back by the controller(150).
