Φ-OTDR disturbance localization of communication optical cable based on moving variance average and spectral subtraction

Φ-OTDR disturbance localization of communication optical cable based on moving variance average and spectral subtraction

To address the issue of low signal-to-noise ratio in disturbance localization on power communication optical cables caused by environmental noise in phase sensitive-optical time domain reflectometry (Φ-OTDR) systems, the Φ-OTDR localization technique is investigated based on moving variance averagin...
