An optical fiber coupler includes a main body and a cover detachably coupled with the main body. The main body includes a coupling member, at least two lenses, at least two optical fibers and a connecting post. The lenses and the optical fibers are mounted on the coupling member. The optical fibers couples with corresponding lenses. The lenses protrudes from the coupling member. The connecting post protrudes from the main body adjacent to the lenses. The cover defines a fixing hole and a covering groove corresponding to the lenses. The fixing hole engages with the connecting post, for positioning the coupling member to the cover. The cover covering the lenses via allowing the at least two lenses to be received in the covering groove.
