Laser-Stabilized Fiber Sensing on Terrestrial Field-Deployed Cable for Enhanced Sensitivity
Rajiv Boddeda, Adrish Sahu, Christian Dorize +5
We demonstrate distributed acoustic sensing on deployed buried cable leveraging laser frequency stabilization and probing code optimization. Our results confirm the capability to a…
Sparsely repeated 21.7 Tb/s Net-Rate Transoceanic Transmission with 266 km Ultra-Long Spans Enabled by Low IMI and Low loss Hollow Core Fiber
Rajiv Boddeda, Carina Castineiras Carrero, Haïk Mardoyan +6
We demonstrate 21.7-Tb/s net-rate transmission across 6660-km with 266-km ultra-long spans of HCF. By exploiting a newly designed GTA-ST-HCF, high-power booster, and adaptive chann…
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…
Experimental Characterization and Model Validation of Interference in Classical-QKD Coexistence Transmission
Lucas Alves Zischler, Amirhossein Ghazisaeidi, Carina Castiñeiras Carrero +4
We present an experimental characterization of coexistence-induced interference in QKD transmission arising from SpRS and FWM, validating a comprehensive semi-analytical model for…
