63 km BOFDA for Temperature and Strain Monitoring

63 km BOFDA for Temperature and Strain Monitoring

We demonstrate (and are the first to do so) 63 km Brillouin Optical Frequency-Domain Analysis (BOFDA) for temperature and strain monitoring using a 100 km fiber loop. The use of BOFDA for long-range applications can be considered a novel approach, as previous investigations focused on the utilizatio...
