About us
AP Sensing is a leading German provider of distributed fiber optic sensing (DFOS) solutions for monitoring railroad infrastructure, including Distributed Acoustic Sensing (DAS) and Distributed Temperature Sensing (DTS). All solutions utilize fiber optic cables to monitor the railway system in real time, ensuring accurate data acquisition across the following application areas:
Rolling stock monitoring
Track condition monitoring
Rail-wheel contact zone defects
Catenary flashover localization
Natural hazard detection
Fire detection
Third party intrusion (TPI), such as vandalism or cable theft

Distributed Acoustic Sensing (DAS)
The AP Sensing’s phase-based DAS system measures the acoustic vibrations on the fiber based on the principles of Coherent Optical Time Domain Reflectometry (C-OTDR). Revolutionary 2P Squared technology of DAS provides a true linear measurement of dynamic fiber length changes generated by strain related to acoustic/vibration signals or by temperature changes.
Distributed Temperature Sensing (DTS)
AP Sensing’s DTS is based on the Raman Optical Time Domain Reflectometry technology (R-OTDR). AP Sensing uses its patented code correlation OTDR (CC-OTDR) that allows the utilization of low optical power. It eliminates any problems with laser degradation and enables worry-free, long-term measurement stability. CC-OTDR technology also offers the advantage of a large optical budget, which is crucial for long-range installations having long lead fibers and short-range systems with high loss.
