Abstract
We report, for the first time to our knowledge, the detection and localization of a loss-inducing perturbation along more than 20-km-long test fiber based on the analysis of transmitted and Rayleigh backscattered powers of an unmodulated continuous-wave light source. Localization of a strong disturbance with an estimated accuracy of 1 m near the source end and 7.5 m near the remote end of the 21.067-km-long single-mode sensing fiber is demonstrated.
