A neurostimulation lead includes fiber optic cable. A human-implantable neurostimulator and neurostimulation lead each include an opto-electric transducer. The opto-electric transducers can be an optical transmitter, an optical receiver, or an optical transducer, that converts: electrical energy to optical energy; optical energy to electrical energy; or both electrical energy to optical energy and optical energy to electrical energy. Neurostimulation-lead electrodes can be activated, and/or lead-status information can be transmitted, over the fiber optic cable, between the neurostimulator and the neurostimulation lead. A neurostimulation-lead power converter may be coupled to a pulse generator of the neurostimulator such that the power converter derives and stores power for the lead from stimulation pulses received from the stimulation-pulse generator.
