Abstract :
The OTDR technique using the stimulated Raman scattering effect (ROTDR) is applied to ultralong multimode optical fibre fault location. In experiment, Stokes light pulses at 1.6 ¿m wavelength, which are the most advantageous for fault location, are used. It is shown that the multimode fibre break, more than 80 km long, is locatable, and fibre loss at 1.6 ¿m is measurable by the ROTDR technique.
