Monitoring system for control of tension in fiber optic communication lines

This article proposes a monitoring system for monitoring the tension of air fiber optic links based on Bragg gratings. The use of Bragg gratings in fiber-optic communication systems and in sensors of physical quantities with the inclusion of similar FBGs combined into a group is considered. A mathematical model for calculating the stretch sensor based on FBG and simulation of the sensor in the OptiSystem program are given. And also describes the principle of operation of the proposed monitoring system. The relevance of such systems increases with the introduction of new information transmission technologies via fiber-optic communication lines. In particular, this task arose when discussing the introduction of systems that use electromagnetic waves carrying angular momentum.
