Abstract

The performance of a coherent OTDR system operating at 1.3 μm is described. Two sources have been used - a Nd:YAG laser and a semiconductor laser with increased coherence. With the latter source, greater than 24 dB one way range has been achieved with accurate determination of fault magnitude.
