Optical fiber connector

An optical fiber connector, comprising:

• a substrate comprising:
• a loading surface defining a first receiving groove and a second receiving groove;
• and
• a sidewall connecting to the loading surface;
• wherein the substrate receives a first light channel passing through the sidewall and extending to the first receiving groove, and a second light channel passing through the sidewall and extending to the second receiving groove;
• and
• a main body positioned on the loading surface, the main body having a top surface away from the loading surface and a bottom surface opposite to the top surface, the main body defining a first through hole and a second through hole passing through the top surface and the bottom surface;
• a first coupling lens received in the first receiving groove, and having a first light converging portion received in one end of the first through hole adjacent to the bottom surface;
• a second coupling lens received in the second receiving groove, and having a second light converging portion received in one end of the second through hole adjacent to the bottom surface;
• a light emitting module positioned on the top surface, and having a light emitting portion aligned with the first through hole;
• and a light receiving module positioned on the top surface, and having a light receiving portion aligned with the second through hole.
