Abstract
This paper introduces the principle of testing fiber strain by using the Brillion scattering.In view of the deficiency of the BOTDR technology in monitoring fiber micro-strains,it presents a Support Vector Regression (SVR)-based method for Optical Power Ground Wire (OPGW)strain analysis.In this method,it builds a model for the frequency shift variations of fi-ber sections under different tensile forces,maps the vector to high-dimensional space using the kernel function and makes re-gression analysis by using the SVR method.Experimental results prove the effectiveness of this algorithm and demonstrate its huge potential in OPGW anomaly detection.关键词
