The Compensation of Radiation-Induced Losses in the Fiber Optic Communication Line in Its Operation Mode

Nowadays high-speed large data exchange is impossible without using the fiber optic communication lines. The scientific and technical progress led to the appearance of large number of factors, which have negative influences on FOCLs. One more of these factors is γ-radiation. It changes fiber properties and leads to the decrease of line efficiency. As the result of properties and structure changes in the optical fiber, color centers appear, i.e. microdefects with a natural frequency of light absorption, and also the radiation-induced losses arise, which are for several hundred times higher than the initial losses in the communication line. It is impossible to transmit the information in such conditions. The optical fiber recovery after γ-radiation influence takes a lot of time, but this process can be significantly accelerated by the compensation of the radiation-induced losses. The article substantiates the necessity to develop a method of compensation of losses in fiber optic communication lines after irradiation, and also describes the method of increasing the rate of relaxation processes based on compensation of radiation-induced losses. The received experimental results are presented.
