A new power supply for fiber optic subscriber systems in transportable containers

Central terminal remote/terminal (CT/RT) fiber optic subscriber systems have been introduced to provide ISDN basic service. RT systems are installed in transportable containers or in customer buildings. A new RT system has been developed with a smaller container and a new power supply. The supply is highly efficient, small and lightweight. This is achieved by applying high-frequency conversion techniques. Test results show that the supply has sufficient capacity for use in RT systems installed in transportable containers
