Keywords:
Distributed fiber optical sensing,fibers and fiber devices for sensing,Fiber sensing application incl. environmental monitoring using optical network
High-resolution fiber sensing is demonstrated over a 7500km trans-oceanic subsea cable, overcoming prior reach limitations. This enables unprecedented deep-ocean monitoring with ~50m spatial resolution, revealing seismic activity, ocean dynamics and cable coupling conditions.
