High-Sensitivity Forward-Transmission Vibration Sensing for Real-World Event Detection in Urban Fiber Networks
We demonstrated a high-sensitivity forwarding-transmission vibration sensing system, enhanced by adaptive time-frequency masking and in-band laser phase noise suppression, detecting and localizing weak real-world events across 80-km deployed fiber with significant ambient vibration interference.
