Simultaneous Inference of Curvature, Angle, and Location of Optical Fiber Bending by Cooperation of Multiple Wavelength Optical Time Domain Reflectometer (OTDR) and Collect, Analyze, and Testing (CAT) Algorithm

Abstract

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.
