Abstract
A first data communication device includes a first semiconductor laser for oscillating with electric power, and outputting feed light to a powered device of a second data communication device; a second semiconductor laser for first signals; a first modulator for modulating first laser light output by the second semiconductor laser to first signal light and outputting the first signal light to the second data communication device; and an optical receiver. The second data communication device includes the powered device having a photoelectric conversion element for converting the feed light into the electric power, a third semiconductor laser for second signals, and a second modulator for modulating second laser light output by the third semiconductor laser to second signal light and outputting the second signal light to the first data communication device. The optical receiver receives and converts the second signal light into an electrical signal corresponding to transmission data.
