Fully Unsupervised Detection of Physical Contacts on Subsea Cables via State-of-Polarization Monitoring
Agastya Raj, Alvaro Doval, Tian Tian +2
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…
DAS-AIS Association Patterns for Vessel Monitoring on an Operational Subsea Fibre Link
Tian Tian, Agastya Raj, Lara Flanagan +4
We present a case study on the Emerald Fibre Bridge Link, an operational subsea telecom cable connecting Dublin and North Wales, examining DAS vessel-related signatures jointly wit…
Deep Learning Based Multi-Step Channel Prediction for Adaptive Underwater Acoustic OFDM Systems
Tian Tian, Ying Zhang, Agastya Raj +2
We develop an adaptive OFDM framework for underwater acoustic communications based on PatchCSI-T, a Transformer-based multistep channel prediction model with feature-independent mo…
Real-Time Capable, Low-latency Upstream Scheduling in Multi-Tenant, SLA Compliant TWDM PON
Arijeet Ganguli, Marco Ruffini
Virtualized Passive Optical Networks (vPONs) offer a promising solution for modern access networks, bringing enhanced flexibility, reduced capital expenditures (CapEx), and support…
