Japanese Patent JP4781953
Kind Code:
B2
Abstract:
To provide a compact optical receiver capable of receiving an optical signal even when a long time passes from power interruption, without using a non-interruption power supply device.
A photoelectric conversion part 8 converts the optical signal into an electric signal in a power supply state. A non-power photoelectric conversion part 14 converts the optical signal into the electric signal in the power non-supply state. An optical signal changeover switch 4 supplies the optical signal to the photoelectric conversion part 8 in the power supply state, and supplies the optical signal to the non-power photoelectric conversion part 14 in the interruption state.
