ABSTRACT:
A communications device, such as a transceiver, is used with a fiber optic communication line, wherein the communications device is powered from a host device. A voltage supply circuit, which comprises a full wave bridge rectifier responsive to data and control signals from the host device, produces plus and minus rectified voltage signals. First and second voltage regulators are responsive to the rectified voltage signals to produce plus and minus regulated voltages, for example ±5 volts, which is sufficient to power the communications device. A charge circuit alternately transfers energy from the plus and minus voltage lines to ensure the presence of plus and minus voltage signals when only positive or negative signals are provided by the host device.
