In connection with the problems existing in Xinjiang electric power communication systems,this paper introduces the working principle of Optical Line Protection (OLP)system,focusing on the measures for ensuring the reliability of the OLP system in the ultra-long lines of the Bazhou-kuche section in practical applications,including optical power compensation,chro-matic dispersion compensation,OSNR compensation and switch time and gives the principle and methods for its concrete im-plementation.The actual test results show that the above-mentioned OLP devices can complete the optical router switching of the backbone trunk lines of the Xinjiang electric power communication system in milliseconds,ensuring normal service commu-nication and greatly reducing the service failure rate.
