Abstract

Utilizing the second Stokes line of the stimulated Raman scattering in a multimode, graded-index optical fiber pumped by a 1.32-μm Nd:YAG laser, we have first demonstrated an optical time domain reflectometry at a wavelength of 1.5 μm for a multimode fiber. As a result, the maximum detectable fault location length of 28 km was successfully obtained. The present technique is applicable to the fault location in ultralong length.
