“…for decorative and landscape lighting [2,3]. Instrumentation based on fiber optic sensors (FOS) is one of the most developing research areas: with applications for temperature [4], displacement [5], pressure [6], bending [7], air quality [8], chemical and biological presence substances [9], angular velocities [10] and other physical parameters. Their universal characteristics contribute to the following: small dimensions and weight, resistance to electromagnetic interference, low power consumption, resistance to aggressive environments, and the ability to work in a wide temperature range.…”

The article discusses the effects of thermal-force on the Panda-type optical fiber. The studies used a wide temperature range. The research used two thermal cycles with exposures to temperatures of 23, 60 and −60 °C. The field of residual stresses in the fiber formed during the drawing process was determined and applied. Panda was considered taking into account a two-layer viscoelastic polymer coating under conditions of tension winding on an aluminum coil in the framework of a contact problem. The paper investigated three variants of coil radius to analyze the effect of bending on fiber behavior. The effect of the coating thickness ratio on the system deformation and optical characteristics was analyzed. Qualitative and quantitative patterns of the effect of temperature, bending, thickness of individual polymer coating layers and relaxation transitions of their materials on the Panda optical fiber deformation and optical characteristics were established. Assessment of approaches to the calculation of optical characteristics (values of the refractive indices and fiber birefringence) are given in the framework of the study. The patterns of deformation and optical behavior of the Panda-type fiber with a protective coating, taking into account the nonlinear behavior of the system materials, were original results.
