Fiber light-guide cladding defects localization on short length of optical fiber

Physical simulation of optical fiber cladding defects and experimental investigation results are described in present paper. By this results it is confirmed that assumption about fiber light-guide cladding defects localization on short length of optical fiber by comparison polarization backscattering characteristic with sliding correlation test is correct. Samples of defects localization on less then 2 km optical fiber with less then 100 m error are represented.
