An exemplary optical fiber connector includes a first surface and a second surface at opposite sides thereof, and a third surface connected between the first surface and the second surface. Two projections are formed on the first surface, and extend a same distance along a direction perpendicular to the first surface. The optical fiber connector defines a fixing recess extending from the second surface towards the first surface and being open at the third surface. The fixing recess has a first inner surface and a second inner surface. The first inner surface is parallel to the third surface. The second inner surface is parallel to the first surface. The first inner surface defines a number of receiving grooves. The optical fiber connector defines a number of receiving holes extending from the second inner surface to the first surface. The receiving holes are aligned and communicated with the receiving grooves, respectively.
