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

Publication number: 20240103215Abstract: An advance in the art is made according to aspects of the present disclosure directed to methods for earthquake sensing that employ a supervisory system of undersea fiber optic cables. Earthquakes and other environmental disturbances are detected by monitoring the polarization of interrogation light instead of its phase. More specifically, our methods monitor the transfer matrix rather than just polarization and isolate disturbance location by monitoring eigenvalues of the polarization transfer matrix. From results obtained we have demonstrated experimentally that we can monitor disturbances that affect signal polarization on a span-by-span basis using High Loss Loop Back (HLLB) paths. It is shown that by measuring the polarization rotation matrix and determining the polarization rotation angle we can identify the span where the disturbance occurred with 35 dB extinction with no limitation on the magnitude of the disturbance and the number of affected spans.Type: ApplicationFiled: September 15, 2023Publication date: March 28, 2024Applicants: NEC Laboratories America, Inc., NEC CorporationInventors: Fatih YAMAN, Shaobo HAN, Eduardo Fabian MATEO RODRIGUEZ, Yang LI, Yoshihisa INADA, Takanori INOUE
