Abstract
Summary
In recent years, long-range Distributed Acoustic Sensing (DAS) has raised significant interest notably due to the improvement in long-range sensing capabilities and the ability to use tens or hundreds of kilometres-long telecommunication cables as dense arrays of acoustic sensors. In this study, we describe laboratory experiments that have been designed to investigate long-range DAS capabilities. In particular, we analyze the sensitivity of the noise floor and the detectability of various signals at different locations along the fibre-optic cable for cable lengths varying from 10 to 200 km. These results can provide guidance on the DAS acquisition parameters to use for specific applications and cable setups.
