Abstract :
The characteristics of three types of power distribution systems for a drop segment of a hybrid optical fiber/coaxial cable telecommunication architecture are compared: DC; low frequency AC; and high frequency AC. It is shown in the paper that the high frequency distribution system has potential advantages in terms of high efficiency, small size of power converters, and low cost of powering. A prototype system which distributes 30 V (RMS) at 128 kHz over coaxial cable is built and experimental results are given which support the high frequency distribution as an attractive and viable option
