An optical fiber connector includes an optical fiber, a body and an optical fiber receiving block. The body includes a top surface, a bottom surface, a front surface, and a rear surface. The top surface and the bottom surface extend from the front surface to the rear surface. The body defines a receiving groove in the rear surface. The body includes a lens portion arranged at the front surface. The optical fiber receiving block is attached on the body in the receiving groove. The optical fiber receiving block defines a through hole therein. The through hole receives the optical fiber. The lens portion is optically coupled with the optical fiber.
