Abstract
Fiber-optic technologies (FOT) have been actively developing over the last 40-50 years, demonstrating wide application and high efficiency. The transmission of light pulses instead of electrical signals has significantly expanded the range of optical fiber applications and increased its effectiveness, allowing telecommunication networks to reach a new level of development. The intensive development of optical fiber production technology and the improvement of its modifications have made it possible to create new and higher-quality systems based on them. The most well-known area of optical fiber application is telecommunication networks for data transmission. However, considering its physical properties, the field of use is expanding, and it can be used as a measurement device, i.e., sensors for measuring certain physical quantities. In this regard, there is a need to research this industry for its effective application in various technical tasks.
