The present invention relates to an optical fiber connector. The optical fiber connector includes a main body, at least two optical coupling lens, a RJ45 joint, a fixed member and at least two fiber. The main body defines a first RJ45 interface, the first RJ45 interface includes a first bottom surface, the first bottom surface defines at least two through holes and at least one first positioning hole. Each optical coupling lens is fixed on the first bottom surface, and the central axes of each optical coupling lens coincide with the central axes of corresponding through hole. The RJ45 joint is located in the first RJ45 interface, and defines a through slot. The fixed member is provided in the through slot, and defines at least two housing hole, the fixed member also positions at least one fixed vertical column, each fixed vertical column is accommodated in the corresponding first positioning hole. Each fiber is housed in a housing hole.
