Pressure Wave Detection and Localization in Deployed Underground Fiber using Coherent Correlation OTDR
arXiv:2412.01320 · doi:10.1364/OFC.2024.M2K.3
Abstract
A deployed fiber with in-house and underground sections is interrogated with a coherent correlation OTDR. The origin and propagation speed of a hammer-generated pressure wave in the underground section is detected and acoustic signals are monitored.
