Abstract: The paper deals with optical fiber distributed sensing based on Mach-Zehnder interferometryfor infrastructure protection. The system is used in the landscape model, where digging canbe simulated. The developed system measures vibrations close to the optical fiber and evaluates theexceeding of the limit value of the signal deviation, on the basis of which the alarm is triggered.This demonstration model is used to demonstrate the possibility of protecting the optical fiber infrastructurefrom mechanical damage, such as optical cable cuts caused by digging activity. The paperdescribes both the design of the demonstration system and the GUI for setting and evaluating alarms.
