Fibre Vibration Sensing and Localization with Cross-Correlation based Neural Network in a Practical Bidirectional Optical Transmission System
We present a CC-CNN localization algorithm for vibration detection over Bristol’s urban fibre network, achieving an 8-km spatial resolution and outperforming pure cross-correlation methods in accuracy and robustness. High-precision time synchronization over the fibre link with aroud 200-ns jitter enables precise localization.
