Abstract: This article deals with the impact of optical fiber bends on the level of optical losses. The main task of this research was to carry out a series of experiments using the optical time domain reflectometer (OTDR VISA) under field operating conditions for obtaining of optical loss parameter’s dependencies from different bending radii of optical fibers and from the fibers number. We have studied the processes of the occurrence of optical losses in the investigated object and elaborated deterministic models of the physics of the phenomena along with the description undelraying physical processes during the bending. As the outcome of the experiment, a number of dependencies of the optical losses intensity from the number of bends in the fiber, the radii and the wavelength is elaborated. A methodology of the calculation of the signal strength from the number of bends is given. During the work, the excessive losses were noted in case of noncompliance with the installation technology and operating rules. The results of cable research are adopted by Kazakhtelecom JSC.
