Results of the development of the way of controlling damages in a fiber-optic link of distributed information-computer network using the integral reflectometry and direct detection methods are presented. It is demonstrated that in time domain the optical reflectometry method is preferable in comparison with the direct detection method. The optical reflectometry method limitation, in time domain, consists in a weak waveform of backward scattering leading to delay in decision making. It is shown how these shortcomings can be removed by using the integral reflectometry method. To improve reliability and increase the speed of operations, it is suggested to use the integral reflectometry method in combination with the direct detection method within one controlling device. The calculation of parameters and structural diagram of the device are presented. Keywords: fiber-optic link, distributed information-computer network, fiber-optic damages, the integral reflectometry method, the direct detection method.
