Publication number: 20240125962Abstract: Method for source localization for cable cut prevention using distributed fiber optic sensing (DFOS)/distributed acoustic sensing (DAS) is described that is robust/immune to underground propagation speed uncertainty. The method estimates the location of a vibration source while considering any uncertainty of vibration propagation speed and formulates the localization as an optimization problem, and both location of the sources and the propagation speed are treated as unknown. This advantageously enables our method to adapt to variances of the velocity and produce a better generalized performance with respect to environmental changes experienced in the field. Our method operates using a DFOS system and AI techniques as an integrated solution for vibration source localization along an entire optical sensor fiber cable route and process real-time DFOS data and extract features that are related to a location of a source of vibrations that may threaten optical fiber facilities.Type: ApplicationFiled: October 11, 2023Publication date: April 18, 2024Applicant: NEC Laboratories America, Inc.Inventors: Yifan WU, Ming-Fang HUANG, Shaobo HAN, Jian FANG, Yuheng CHEN, Yaowen LI, Mohammad KHOJASTEPOUR
