Abstract:
In presented work, we focus on an experimental comparison of high sensitivity and performance interferometric based method using very narrowband laser and methods based on the passive state of polarization changes detection in fiber with simple on-off keying modulation. The mechanical stress from the environment causes changes in the state of polarization. Therefore it is possible to use its detection as an early warning system for a fiber cut. The results show that cheap and simple setup with detection of a change of state of polarization achieves a sufficient sensitivity for continuous disturbances up to 100 Hz and also the short intensive pulses like from digging.
