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…
High Sensitivity ϕ-OTDR over Long Distance with Polarization Multiplexed Codes
Christian Dorize, Elie Awwad, Jérémie Renaudier
Newly introduced polarization diversity probing codes are suggested to enhance the sensitivity and bandwidth performance of differential phase-sensitive distributed OTDR systems. T…
Enhancing performance of coherent OTDR systems with polarization diversity complementary codes
Christian Dorize, Elie Awwad
Monitoring the optical phase change in a fiber enables a wide range of applications where fast phase variations are induced by acoustic signals or vibrations in general. However, t…
