Threat Classification on Deployed Optical Networks Using MIMO Digital Fiber Sensing, Wavelets, and Machine Learning
Khouloud Abdelli, Henrique Pavani, Christian Dorize +4
We demonstrate mechanical threats classification including jackhammers and excavators, leveraging wavelet transform of MIMO-DFS output data across a 57-km operational network link.…
Optimal Probing Sequences for Polarization-Multiplexed Coherent Phase OTDR
Christian Dorize, Elie Awwad, Sterenn Guerrier +1
We introduce dual-polarization probing codes based on two circularly shifted frequency sweep signals enabling perfect channel estimation. This is achieved with a probing length equ…
Towards Polarization-Insensitive Coherent Coded Phase OTDR
Sterenn Guerrier, Christian Dorize, Elie Awwad +1
We explore the alternatives for interrogating a fiber sensor from the polarization point of view, and demonstrate a better accuracy with dual polarization probing for coherent phi-…
Introducing Coherent MIMO Sensing, a fading-resilient, polarization-independent approach to phase-OTDR
Sterenn Guerrier, Christian Dorize, Elie Awwad +1
Nowadays, long distance optical fibre transmission systems use polarization diversity multiplexed signals to enhance transmission performance. Distributed acoustic sensors (DAS) us…
