Numerical Model of a Multiple-Input-Multiple-Output Distributed Acoustic Sensing System with Joint Phase and Birefringence Estimation
Diane Prato, Mehran Mokhtari Sheramin, Renaud Gabet +1
In this work, we introduce and experimentally validate a numerical model for a Multiple-Input-Multiple-Output Distributed Acoustic Sensing (MIMO-DAS) system that accounts for dynam…

Sequence Selection with Dispersion-Aware Metric for Long-Haul Transmission Systems
Jingtian Liu, Ãlie Awwad, Hartmut Hafermann +1
We introduce a novel sign-dependent metric: the energy dispersion index (EDI) of sequences that endured chromatic dispersion, denoted as D-EDI, which exhibits a more accurate oppos…
