Paper Abstract

Rayleigh backscatter from (near) singlemode fibers can be measured with centimeter-scale resolution using a photon-counting optical time domain reflectometer (OTDR) technique. It is shown that high resolution measurement of changes in backscatter signals can be constrained by spatially-varying polarization fluctuations in the backscatter signal, which can produce large changes in detected signals using a standard OTDR configuration. The magnitude of these effects is explored, and a means of minimizing their influence on the accuracy of loss measurement is described.
