Abstract :
Powering alternatives for hybrid fiber/coax networks of the `Information Superhighway´ are presented. It is found that a 90 V, 60 Hz trapezoidal waveform voltage distribution over the distribution cables provides a good compromise between safety, corrosion, and distribution losses. Further, it is shown in the paper that a low frequency distribution throughout the network is good enough for initial deployment of the networks. However, for the future networks it will be significantly advantageous to distribute high frequency AC over the drop cables (hybrid power distribution) as it results in higher conversion efficiency, lower weight and cost
