Demonstration of MIMO-DFS over 100km of unamplified SSMF Link using Active Laser Drift Stabilization and Optimized Probing Codes
Rajiv Boddeda, Christian Dorize, Pierre Brochard +3
We estimate the laser frequency noise impact on coherent sensing using Distributed Fiber Sensing model. By stabilizing the laser in the estimated frequency zone, we demonstrate red…

High-Resolution Coherent DFS Over 20km Ultra-Low-Loss Anti-Resonant Hollow-Core Fiber with Live Traffic
Rajiv Boddeda, Arnaud Dupas, Haïk Mardoyan +10
We demonstrate sub-meter resolution Coherent DFS and detect acoustic oscillations using a stabilized laser on 20 km of anti-resonant HCF with <0.10 dB/km loss without impacting liv…
