Abstract

Tunable OTDR based on self-locked RSOA for in-line monitoring of WDM-PON is proposed and demonstrated. The characteristics of self-locked RSOA were experimentally studied. The tunable OTDR was successfully demonstrated for a range of 25 nm, having a dynamic range of about 15 dB. Under in-service state of 2.5-Gb/s data, the power penalty induced by the line monitoring channel was about 0.1 dB at BER of 10^-9. The proposed tunable OTDR is cost-effective and useful to monitor the status of WDM-PON.
