This paper presents the performance of a power distribution system for hybrid fiber/coax networks. The power scheme uses 90 V 60 Hz trapezoidal voltage distribution over the network. A simulation model of the proposed distribution system is developed, and the performance under steady-state, transient, and dynamic conditions is studied. The system loading capability as a function of cable size and distribution length is presented. It is shown in the paper that synchronous power sources can provide a much larger distribution reach than asynchronous sources. In order to ride through a fault in the system, it is found that the power supplies used in the coax node and the home termination unit should have enough holdup time capability. A system designed in this manner is inherently stable
