The article describes the construction and operation principle of the fibre optic pulse interferometer, which allows detection of mechanical disorders in fibre optic transmission line. Operation of this system is based on the optical pulses interference. Configuration of the system allows stable work of pulse interferometer over distances of several kilometres, with compensation impact of environmental conditions. Unique system detection capabilities obtained by using two independent criteria for alarm signal excitation. The aim of the research was to determine the usefulness of the proposed system to protection of information transmission via fibre-optic transmission networks.
