Abstract

Summary form only given. We have demonstrated an in-service supervisory CATV video transport system using both the 1310 nm and 1650 nm OTDR for the first time to our knowledge. Simultaneous fiber-fault location and EDFA status monitoring have been achieved without degrading the video performance in a 80-NTSC-channel 77.6-km fiber link. This supervisory technique applied to the CATV supertrunk link can efficiently improve the system reliability and reduce the disaster-repairing time of EDFA-failure and link-faults.
