Abstract :
A fiber optic interferometric system to detect, classify and locate phase sensitive events in fiber optic cables, with sufficient accuracy and early warning capabilities is presented. The system is capable of detecting events including vibration and localized temperature. The system makes use of two standard fibers that are already installed in the cable. The monitoring is done from a centralized location where the detection opto-electronics is located. Spatial event localization within 200m is demonstrated for a monitoring length of 40Km.
