Photoelectric conversion device and optical fiber coupling connector

An optical fiber coupling connector comprising:

• a photoelectric conversion device comprising:
• a circuit board;
• a plurality of light-emitting modules mounted on the circuit board;
• a plurality of light-receiving modules mounted on the circuit board and being apart from the light-emitting modules;
• and
• an optical coupling module mounted on the circuit board and comprising a first optical surface, a second optical surface perpendicular to the first optical surface, a reflection surface oblique relative to the first optical surface and the second optical surface, and a plurality of first converging lenses, the first converging lenses formed on the second optical surface and corresponding to the light-emitting modules and the light-receiving modules, the first optical surface face the light-emitting modules and the light-receiving modules, the reflection surface configured for reflecting parallel light beams from the first optical surface toward the first converging lenses and reflecting parallel light beams from the first converging lenses toward the first optical surface;
• and
• a lens strip mounted on the circuit board and comprising a body portion and a plurality of second converging lenses, the body portion comprising an upper surface and a lower surface opposite to the upper surface, the lower surface defining a receiving cavity, the second converging lenses formed on the upper surface, the light-emitting modules and the light-receiving modules received in the receiving cavity and aligned with the second converging lenses, and the lens strip configured for converting light beams from the light-emitting modules into parallel light beams and directing the light beams into the optical coupling module, and converging and directing light beams from the optical coupling module to the light-receiving modules;
• and
• a plurality of optical fibers each comprising a core portion and a cladding layer, and the core portions aligned with the respective first converging lenses.
