Abstract:
1. A photoelectric coupling module, comprising: a substrate comprising a bearing surface; a photoelectric unit positioned on the bearing surface, and comprising at least one light emitter and at least one light receiver; a lens module positioned on the bearing surface, and comprising a top surface, a bottom surface opposite to the top surface, and a side surface connected between the top surface and the bottom surface; the lens module defining a first recess in the top surface, a second recess on the bottom surface, and a third recess on the side surface; the first recess comprising a reflection surface tilting about 45 degrees relative to the bearing surface; the second recess comprising a lower surface parallel to the bearing surface; the third recess comprising a connecting surface perpendicular to the bearing surface; the reflection surface facing the connecting surface and the lower surface; at least two first lenses formed on the bottom surface; and at least two coupling portions extending outward from the connecting surface; each coupling portion comprising a receiving part and a second lens received in the receiving part; optical axes of the first lenses crossing optical axes of the second lenses of the at least two coupling portions on the reflection surface; the first lenses aligned with the at least one light emitter and the at least one light receiver.
