Fully Unsupervised Detection of Physical Contacts on Subsea Cables via State-of-Polarization Monitoring

We present a fully unsupervised Fast-Slow DSVDD detector for continuous State-of-Polarization monitoring on a deployed subsea cable. Trained without event labels, it ranks all five confirmed trawler contacts within the top 13 of 122,174 recordings and surfaces additional corroborated cable-contact events.

Multi-Modal Fiber Sensing for OffshoreEnvironmental and Infrastructure Monitoring

Monitoring a 118 km subsea cable using Distributed acoustic, state-of-polarization, and Brillouin sensing captured storm-induced strain up to $\approx 0.003 \mu\epsilon$ (dynamic) and $\approx 180 \mu\epsilon$ (static), demonstrating consistent yet distinct modal responses to environmental loading.
