Zusammenfassung:A fiber optic sensor unit for detecting a mechanical force acting on a rail includes at least a first sensor fiber, a first elongated fiber optic strain sensor and a second elongated fiber optic strain sensor. The first sensor fiber includes the first strain sensor and is characterized in that the at least one sensor fiber is attached to a sensor plate. The first fiber strain sensor and the second strain sensor are arranged in an x-type or v-type geometry, wherein the first strain sensor and the second strain sensor are arranged in an angle of 60° to 120°, in particular of 90°, to each other. Measurements with increased amplification of the measurement signal and improved raw data can be made.
