Study of Extracting Information from Distributed Optical Fiber Sensing System Based on P-OTDR

This paper first introduced the distributed sensing principle of the polarization sensitive optical time_domain reflectometer(P_OTDR). On this basis, we investigated two methods for the extraction of the state of polarization(SOP) evolution from the tested backscattered signal in detail. The analysis results show that both the digital average and deconvolution could be used for enhancing the Signal_to_Noise ratio (SNR) and system spatial resolution. The methods can be applied to a real distributed fiber optical sensor system.
