Abstract
A photoelectric coupling module includes a substrate, a photoelectric unit, and a lens module. The substrate defines a positioning recess. The photoelectric unit is positioned on the substrate. The lens module includes a reflection surface, a plurality of first lenses, and a plurality of second lens. Optical axes of the first lenses cross optical axes of the second lenses on the reflection surface. The lens module further includes a positioning portion extending downward from a bottom surface, and the positioning portion is received in the positioning recess. The first lenses are aligned with the photoelectric unit.
