423.7 + 426.5 Tb/s GMI Bi-Directional HCF Transmission
Jiaqian Yang, Romulo Aparecido, Eric Sillekens +28
We demonstrate OESCL-band same-wavelength bi-directional transmission over 60 km HCF with 42.5 THz bandwidth, achieving GMIs comparable with the highest unidirectional SMF data-rat…
High-Resolution Trans-Oceanic Distributed Acoustic Sensing Enabled by a Bi-Directional Sensor Implementation
Mikael Mazur, Nicolas K. Fontaine, Roland Ryf +14
We demonstrate continuous distributed acoustic sensing over a 4400km long undersea cable. Bi-directional operation improves the strain signal-to-noise rate by >20dB, enabling 88000…
Submarine Cable Deep-Ocean Observation of Mega-Thrust Earthquake and Tsunami with 44,000 100-m Spaced Sensors
Mikael Mazur, Nicolas K. Fontaine, Roland Ryf +13
We detect the recent M8.8 mega-earthquake in Eastern Russia, on a 4400km long active telecom cable in the Pacific Ocean. The resolution achieved 100m represents the highest spatial…
Global Seismic Monitoring using Operational Subsea Cable
Mikael Mazur, Martin Karrenbach, Nicolas K. Fontaine +11
We report tele-seismic waves detection from multiple earthquakes on an operational subsea cable from Iceland to Ireland. Using per-span laser interferometry with 100km spacing, we…
Large Language Model-Driven Cross-Domain Orchestration Using Multi-Agent Workflow
