複数波長Optical Time Domain Reflectometer（OTDR）と Collect, Analyze, and Testing（CAT）アルゴリズムによる光伝送路における 曲げ曲率，角度，並びに発生位置の同時判定技術

抄録

We present novel network diagnosing method to enable simultaneous detection of optical fiber bending diameter and its longitudinal length. The proposed method is based on co-operation of CAT autonomous network diagnosing platform and multiple wavelength OTDR. We have successfully confirmed the method experimentally at bending diameters of 20 and 15 mm by using the measured data from OTDR at 1550 and 1625 nm in wavelength.
