Abstract
The present disclosure provides a method and system of identifying macro-bends in at least one test fiber. The method includes generation of modulated optical pulses and scrambling the state of polarization of the modulated optical pulses to random states of polarization. The method includes injection of the modulated optical pulses in at least one test fiber and reception of backscattered optical pulses and splitting of the backscattered optical pulses to a first optical component and a second component. The method includes measurement of a first power of the first optical component and a second power of the second optical component of the backscattered optical pulses. The method includes calculation of discrete values of polarization dependent loss as a function of distance and identification of the macro-bends by analysis of peaks in one or more plots of one or more traces of the discrete values of the polarization dependent loss.
