Optoelectronic transmission device having solar cell unit

An optoelectronic transmission device, comprising:

• a base;
• a first optical fiber configured to transmit first light;
• a second optical fiber configured to transmit second light;
• an optical signal source positioned on the base and configured to emit the first light;
• a light detector positioned on the base and configured to receive and convert a first part of the second light into electrical signals;
• a solar cell unit positioned on the base and configured to receive and covert a second part of the second light into electrical energy;
• a carrier positioned on the base, the carrier comprising a body and two supports, the body comprising a first surface, a second surface and a top surface, the top surface connecting the first surface and the second surface, the first surface and the second surface being at opposite sides of the body, the carrier having a first through hole and a second through hole, the first through hole and the second through hole being defined from the first surface to the second surface, two fastening recesses and two fiber receiving grooves being defined in the top surface and extend from the first surface to the second surface, the two fiber receiving grooves arranged between the two fastening recesses and in communication with the first through hole and the second through hole respectively, the first optical fiber received in the first through hole, the second optical fiber received in the second through hole;
• a reflector positioned on the base and covering the light detector and the optical signal source, the reflector configured to internally totally reflect the first light emitted from the optical signal source to the first optical fiber and reflect the first part of the second light from the second optical fiber to the light detector and reflect the second part of the second light to the solar cell unit;
• and
• a power storage unit electrically connected to the solar cell unit for storing the electric energy, the power storage unit configured to power the light detector and the optical signal source.
