Abstract
A photoelectric conversion device includes a circuit board, a first light emitting module, a first light receiving module, a second light emitting module, a second light receiving module, and an optical coupling member. The light emitting modules and the light receiving modules are mounted on the circuit board. The optical coupling member includes a first reflective surface obliquely connected to the light incident surface, four converging lenses, a second reflective surface, and a third reflective surface. The converging lenses are formed on the light incident surface. The first reflective surface defines a recess for receiving the second and third reflective surfaces. The third converging lens is fed by the second reflective surface and the fourth converging lens is fed by the third reflective surface.
