Distributed acoustic sensing

Distributed Acoustic Sensing (DAS) is a technology for the localization and analysis of noises and vibrations through changes in light pulses in optical fibers .

For example, train trains can be located more precisely using fiber optic cables that have been laid at a defined distance from the track than is possible with conventional technologies such as track circuits or axle counters . Vehicle equipment is not required with this method.
