ABSTRACT:
An optical transmission system includes a current and standby optical transmission lines for transmitting digital information signals in parallel. An information string phase difference detector detects the phase difference between the received digital information strings from the respective optical transmission lines. The optical transmission system also includes an optical receiver arranged in the receiving side for receiving the transmitted light signals. A controller changes the wavelengths of the light signals that are received by the optical receiver, based upon the detected phase difference which is detected by the phase difference detector.
