Abstract :
Summary form only given. In conclusion, we have investigated the SRS effect in OTDR-monitored AM video lightwave system. Negligible CNR/CSO/CTB degradation, but accompanied with baseband video distortion, due to the OTDR monitoring is only observed at 1650 nm. This makes the 1310-nm wavelength a good candidate for in-service monitoring. After reducing the peak power of the OTDR probe pulses at the expense of reduced dynamic range, the 1650-nm wavelength can also be used in lightwave CATV system.
