Abstract

The effect of atmospheric electricity on the operation of fiber-optic communication lines has been studied on an electrophysical installation designed to simulate lightning in laboratory conditions. The change in the polarization state of the linearly polarized radiation transmitted over a fiber-optic cable has been measured using a high-speed polarimeter. During the experiments with a frequency of 100 MHz, a change in the polarization state has been monitored. For the first time, rapid rotations of the plane of polarization, the formation of elliptical polarization, and changes in the angle of ellipticity when exposed to atmospheric discharges on an optical cable have been recorded with precise reference. The effect of maintaining the radiation polarization state when the high voltage is turned off at an electrophysical installation has been discovered.
