“…Among interferometric methods for perimeter security, it is also very advantageous to use a dual Mach-Zehnder interferometer (DMZI), which is most often used to detect cutting, and manipulation with optical fibers [12] or for the classification of falling rocks, climbing, and hitting fibers [13] and other possible typical intrusion events [14]. With DMZI, there is also the possibility of event localization [15].…”

This paper aims to evaluate detection algorithms for perimeter security systems based on phase-sensitive optical time-domain reflectometry (Φ-OTDR). Our own designed and developed sensor system was used for the measurement. The main application of the system is in the area the perimeter fencing intrusion detection. The system is unique thanks to the developed motherboard, which contains a field-programmable gate array (FPGA) that takes care of signal processing. This allows the entire system to be integrated into a 1U rack chassis. A polygon containing two different fence types and also cable laid underground in a plastic tube was used for testing. Edge detection algorithms using the Sobel and Prewitt operators are considered for post-processing. The comparison is made based on the signal-to-noise ratio (SNR) values calculated for each event. Results of algorithms based on edge detection methods are compared with the conventional differential method commonly used in Φ-OTDR systems.

“…Another option is to measure vibrations using interferometers. The most commonly used techniques employ the Mach–Zehnder interferometer (MZI), which can be used, for example, to secure gas turbines [ 13 ]; the Michelson interferometer (MI), which is commonly used for perimeter security [ 14 ]; or the Sagnac interferometer (SI), which is also used for perimeter security [ 15 , 16 ]. The use of the MZI and MI requires the use of reference fibers [ 17 ], which can be complex to implement in real infrastructures.…”

Fiber-optic network infrastructures are crucial for the transmission of data over long and short distances. Fiber optics are also preferred for the infrastructure of in-building data communications. In this study, we use polarization analysis to ensure the security of the optical fiber/cables of the physical layer. This method exploits the changes induced by mechanical vibrations to polarization states, which can be easily detected using a polarization beam splitter and a balancing photodetector. We use machine learning to classify selected events that violate the safety of the physical layer, such as manipulation or temporary disconnection of connectors. The results show the resting state can be accurately distinguished from selected security breaches for a fiber route subjected to environmental disturbances, where individual events can be classified with nearly 99% accuracy.
