Field Tests of Impulsive Acoustic Event Detection, Localization, and Classification Over Telecom Fiber Networks

We report distributed-fiber-optic-sensing results on impulsive acoustic events localization/classification over telecom networks. A deep-learning-based model was trained to classify starter-gun and fireworks signatures with high accuracy of > 99% using fiber-based-signal-enhancer and >97% using aerial coils. © 2022
