Abstract

A time division multiplexing optical time domain reflectometry (TDM-OTDR) based on multi-frequency probe light and directly synthesizing heterodyne intermediate frequencies (IFs) is proposed and experimentally demonstrated. Five time division multiplexing probe frequencies are obtained by synchronous control of an arbitrary waveform generator and a phase modulator. Experimental results achieve 6.5dB dynamic range enhancement, compared with conventional coherent OTDR.
