TīmeklisIl dispositivo FEBUS A1-R offre un rilevamento acustico in genere ogni 2 m lungo diverse decine di chilometri con cavo in fibra ottica distribuita sull’infrastruttura. Il dispositivo FEBUS A1-R può essere collegato ai cavi in fibra ottica già presenti in sito. L’unico requisito è che la fibra ottica sia in modalità “single”. TīmeklisA second fibre in the same cable, was interrogated simultaneously by a FEBUS A1 system (FEBUS OPTICS) from 2 to 9 December 2024 with a spatial resolution and a gauge length of 5 m at a sampling frequency of 200 Hz. To validate the DAS measurements, gathered by both systems, two broadband seismometers (Trillium …
