Abstract
A 1.6 μm band OTDR that is useful for optical transmission lines maintenance is reported. A synchronous Raman fiber amplifier (RFA) is employed to increase the dynamic range of the OTDR. Experimental results show that the dynamic range is extended to 25.7 dB with a spatial resolution of 100 m by using the RFA.
