Detection and localization of defects in optical fibers based on monitoring of the polarized backscattered signal

摘要

This paper is concerned with the applications of polarization reflectometry for identification and localization of defects of various types in the fiber optical lines. The methods of physical simulations of various defects in optical fibers are described. The methods and algorithms for polarization optical time domain refiectometer (POTDR) data processing are represented. The results of experimental measurement are represented.
