Abstract :
A new method of fault location for an ultra-long single-mode optical fibre is proposed. It uses the Stokes light pulses as a probing pulse, which is generated by the stimulated Raman scattering effect in the measured fibre. Experimental results show that the fibre broken points with no Fresnel reflection up to 52 km are observable with this method.
