Journal of Tashkent Institute of Railway Engineers


This article discusses the problems of using a fiber-optic transmission line under control and monitoring the voltage of track relays in station rail circuits. A functional diagram of the fast and central equipment of a fiber-optic transmission line and their interconnection are shown. Several different network modules for organizing data transfer are considered. Comparative analyzes are given, problems that arise during the operation of network modules and their solutions are described. As a result of the analysis, the optimal version of the network module was selected and recommendations for developing its software are given
