Original Abstract

The paper describes the possibilities of using the detection of fast and slow changes in the state of polarization for the detection of vibrations by an optical single-mode (SM) fiber. The system consists of a polarization beam splitter and a balanced photodetector. This sensing system is cost-effective, which contributes to its use in real operation. On the basis of an experiment with buried fiber near the railroad, the possibility of detecting vibrations with this system was proved. It is possible with simple analyzes to recognize the types of trains and their speed.
