Abstract

A method for manufacturing an optical fiber includes melting an end of a crystal material and drawing the molten end of the crystal material to form a crystal filament. Conductive paint is coated on two surface sections of the crystal filament to form internal positive and negative electrodes not electrically connected to each other. The crystal filament is placed into a heat resistant tube that is heated until an outer layer of the crystal filament melts and adheres to an inner periphery of the heat resistant tube, with a center of the crystal filament remaining as a solid core. Conductive paint is adhered to two ends of the crystal filament to form external positive and negative electrodes electrically connected to the internal positive and negative electrodes, respectively. The optical fiber thus formed can serve as a photoelectric optical fiber for transmission of current signals.
