“…MPs are based on unidirectional coupler, meaning that the jamming signal will be inserted in the counter direction of propagation of the service channel to be disturbed. However, the reflectance of the network element input port will cause the reflection of a portion of the jamming signal back into propagation direction of the link traffic [11] as shown in Fig. 3.…”

“…If there is neither encryption procedure nor steganography of the service channel, it is possible to prevent recovery of the channels extracted from the optical monitoring port by proceeding to an optical transformation at the MP consisting of adding infinite replica of the signal with a given delay and attenuation as proposed in [11]. This has been demonstrated for 112 Gb/s DP‐QPSK and 240 Gb/s DP‐16QAM modulations formats.…”

“…As shown in Fig. 15, the optical circulator has the ability to reroute the attacking signal into a photo‐detector to create an alarm of intrusion to be reported to the network management system [11].…”

The article presents the results of research aimed at solving important production issues related to the theft of power cables and reducing the reliability of electrical networks with a voltage of 0.4 kV. To implement the security system, a single-mode optical fiber and a hardware and software complex for data processing were used. The results of the work can be used in security systems for various purposes, including telecommunications and construction systems. During the experiments, it was found that the photoelasticity effect occurs during mechanical action on the optical fiber, which causes changes in the refractive indices of the shell and core, while the properties of light change. In contrast to the known security systems and methods of fixing violations, a high-resolution television matrix is used, and not a photodetector device that records only changes in intensity. The television matrix is installed at the output of the optical fiber and records all changes in the light spot, and the hardware and software complex converts these changes into numerical values.
