SagnacAssisted Enhanced OTDR for Distributed Acoustic Sensing: A Standardized Benchmark and Engineering Evaluation Framework
Researchers have developed an enhanced fiber-optic sensing system that combines phase-sensitive optical time-domain reflectometry with Sagnac interferometry to improve distributed acoustic sensing (DAS) performance over long distances. The new architecture addresses signal degradation issues and achieves 89.79% accuracy in acoustic event recognition, with an open-source benchmark framework for future development.
