DAS operates through the principle of coherent optical time domain reflectometry to interpret the backscattered light within an optical fiber to sense the pressure and strain fields around the cable. In our installations, every ten meters of standard telecommunications fiber becomes a new “virtual microphone” and an independent system can handle forty or more kilometers of cable. Thus, one system can comprise more than 4000 of these virtual sensors, each with a useful bandwidth of over 1 kHz. In our webinar, we will introduce the technology, its current application areas, and present earthquake and seismic data.
