Electric power transmission system

摘要

An electric power transmission system includes an electrical-optical conversion device and multiple photoelectric conversion devices converting electricity to light. The electrical-optical conversion device includes a high-voltage source, a laser diode unit, a light combiner, and multiple optical fibers. The laser diodes receive the high-voltage source. The light combiner includes multiple first input ends and multiple first output ends. A first optical fiber interconnects a laser diode and a first input end. An end of a third optical fiber optically connects to a first output end. Each photoelectric conversion device includes a second light splitter, further optical fibers, and a photodiode unit. The second light splitter includes a third input end and a plurality of third output ends. The third input end optically connects to another end of a third optical fiber. A fourth optical fiber optically interconnects a third output end and a photodiode.
