ABSTRACT:
A light driven remote system and power supply therefor that includes a laser diode that provides pulses of light to a fiber optic cable. The pulses of light are detected by a remote photodiode that is connected in parallel with a step-up transformer. The output of the step-up transformer is filtered to provide power for a remote system. Data transmission from the remote system is synchronized with transmission of light to the photodiode.
