One fiber equals thousands of sensors
With fiber optics, the fiber itself is the sensor. Laser pulses sent through a standard telecom fiber continuously measure temperature and vibrations with a high level of accuracy.
Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) are fully distributed systems that can measure temperature and vibrations several tens of kilometers of fiber at a time.
