INVESTIGATION OF ADDITIONAL LOSSES OF FIBER-OPTIC CONDUCTORS OF TYPE G-652 THAT OCCUR DURING BENDING

One of the problems modern information transmission systems is introduction new methods protecting transmitted over fiber-optic lines. Currently, unauthorized access are emerging, which being improved and developed every year. Within framework this work, studies additional losses during bending optical fiber were carried out in order to create an automatic control system for that occur mechanical action leading its bending. For purpose, practical experiments conducted measure with multiple bends a computer program was created based on data obtained. With help program, it possible estimate when wavelength changes from 1310 1625 nm angle indicators 45 135 degrees. The also allows you automatically approximate values occurring different variations angles their number. study will allow future develop and, they change, issue warning signal about connection cable.
