Abstract :
We propose and demonstrate a tunable optical time-domain reflectometer (OTDR) for in-service monitoringof wavelength-division-multiplexed passive optical networks (WDM-PONs). The proposed method is proved for different continuous wavetuneable laser sources (CW TLS), and uses semiconductor optical amplifier (SOA) as a switch for the probe signal. We also improve the results using different methods to mitigate the interference effects.
