Patent ID: 8787764

Claim:
A photoelectric composite wiring component comprising: an optical wiring for transmitting an optical signal; an electrical wiring for transmitting an electrical signal; a light emitting element provided at one end of the optical wiring; a light receiving element provided at another end of the optical wiring; a light emitting element drive circuit for driving the light emitting element; an amplifier for amplifying a light receiving current of the light receiving element; a transmission path switching mechanism for switching a transmission path of a transmission signal to transmit the transmission signal over an electrical transmission system that transmits the transmission signal as the electrical signal when the transmission signal is low-rate, and to transmit the transmission signal over an optical transmission system via the optical wiring when the transmission signal is high-rate; an optical power monitor circuit for monitoring a light receiving current flown through the light receiving element; and wherein the transmission path switching mechanism comprises: a transmission gate element for electrically or mechanically switching an electrical transmission path of the electrical transmission system to a conductive state or non-conductive state; and an amplifier control element for switching the amplifier to an active state or a non-active state based on a monitoring result of the optical power monitor circuit.
