Digital Railways

Fiber Optic Sensors used as a new digital train detection & traffic management system

Fiber Optic Sensors monitor and locate in real time interference on the railway network and provide a train tracking system.

Fosina has partnered with a global railway system integrator to provide an end-to-end solution using distributed fiber-optic sensors to detect hazards from foreign objects, to track and monitor trains and the environmental impact on the railway network. Thanks to our expertise in developing customized and leading fiber-optic sensing technologies, Fosina has developed the DxS, a world-class distributed sensor that is enabling the railway industry to monitor multiple events simultaneously. Compared to existing technologies in the market, DxS reaches a longer fiber range for each interrogator.

The environmental qualification and smaller footprint of the DxS allow our clients to deploy this technology globally, sustainably, and reliably.

animals intrusions

Detection of intrusions, such as animals or unauthorised people, using fiber optic sensing.


Connect one end of a fibre optic cable deployed along the railway to the Fosina DxS interrogation unit. Acquire data continuously to monitor in real-time, along the entire length of the fiber optic cable, various types of events simultaneously such as the location of trains, speed, length and detect hazards such as intrusion or anticipate maintenance issues such as flat wheels.
