Laser-Stabilized Fiber Sensing on Terrestrial Field-Deployed Cable for Enhanced Sensitivity

arXiv:2606.07251 · doi:10.1364/OFC.2026.M3J.3

Abstract

We demonstrate distributed acoustic sensing on deployed buried cable leveraging laser frequency stabilization and probing code optimization. Our results confirm the capability to accurately localize weak events with high resolution and sensitivity over 80 km.
