An optical fiber coupling connector includes a board, a light receiving device, two light emitting devices, a controller and an optical coupling lens. The optical coupling lens includes three main bodies, each includes a bottom surface, a top surface, an alignment surface, a first and a second side surface, a third side surface obliquely connected to the first side surface, and a fourth side surface obliquely connected to the second side surface and connected to the third side surface at a second edge. The alignment surface, the first side surface, the third side surface, the fourth side surface and the second side surface are connected to each other end to end in that order. The third side surface of each one of the main bodies contacts the fourth side surface of an adjacent one of the main bodies. At least three optical fibers positioned to the optical coupling lens.
