Abstract: Between civil ATC centers, optical cables are always used to transmiss long distance, high-bandwidth service. This paper takes the optical cable fault as an example, to determine the cause and the of the cable failure and the location of the attenuation by using optical power and meter OTDR meter. Then, it propose methods of troubleshooting and route optimization to eliminate hidden dangers of transmission in the end.

Key words: long distance optical cable; transmission hidden danger; fault analysis; route optimization
