Abstract

Article deal of the problematic of impact fixing optical fiber for measuring the deformation with the distributed system known as Brillouin Optical Time Domain Reflectometry (BOTDR). The measurement principle of BOTDR system based on scanning of Brillouin frequency. Authors focused on monitoring changes Brillouin frequency for various bends and size of the substrate layer in combination with different types of fixing materials. We used distributed system DiTEST STA-R Omnisense. For the analysis was used a standard telecommunication optical fiber G.652.D. Deformation of the optical fiber was carried out by bending at a special tool. This article aims to find the most suitable method of implementing a fiber-optics for practical applications. It showed that it is necessary to pay attention to the size of the substrate layer and the fixing material to optimize the sensitivity in the measurement of mechanical deformations and the forces.
