介绍了使用布里渊散射测试光纤应变的原理，针对BOTDR(布里渊光时域反射仪)技术难以捕捉光纤微应变的不足，提出了一种基于支持向量回归的 OPGW(光纤架空地线复合缆)应变分析方法。该方法对光纤段在不同拉力条件下的频移变化进行建模，建立频移向量并运用核函数思想将向量映射至高维空间，通过支持向量回归对频移向量进行回归分析。实验证明了该算法的有效性，并显示了该算法在 OPGW异常检测中的巨大潜力。

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.
