Patent number: 9664863Abstract: A method and system for affixing multi-core fiber (MCF) within a ferrule includes a UV light source and a light guide. MCFs are placed into epoxy filled holders, e.g., channels or v-grooves, of a ferrule. A first MCF in a first holder is clocked to orient its cores to a desired position. The light source is activated, and the light from the light guide is launched into a cladding layer of the first MCF. The light in the cladding layer will stay in the cladding layer until it reaches the portion of the first MCF in contact with the epoxy, where the light will leak out due to the similarity in the index of refraction. The leaking light will at least partially cure the epoxy to affix the first MCF within the first holder. The process may then be repeated for the remaining MCFs, so that each MCF may be clocked and affixed selectively rather than collectively.Type: GrantFiled: January 8, 2014Date of Patent: May 30, 2017Assignee: CommScope, Inc. of North CarolinaInventors: Timothy W. Anderson, Jeffrey D. Nielson

Patent number: 9645327Abstract: A molded waveguide side-facet coupler to facilitate an optical connection between optical side-facets and a fiber optic connector is disclosed. Instead of molding the side-facet coupler with the external mounting surface disposed on an external surface of the mold, the mold for the side-facet coupler is provided such that the mounting surface of the side-facet coupler is provided as a molded internal recess surface. The moldable material for the side-facet coupler is disposed around a recess core that is part of the mold, thereby forming a unitary component having at least one internal recess surface for providing an external mounting surface for the side-facet coupler. As the molded material cures around the core structure, the external surfaces of the unitary component pull away from internal surfaces of the mold, and shrink around the core structure. Thus, the internal recess surface of the unitary component is formed within narrower, repeatable tolerances.Type: GrantFiled: June 9, 2014Date of Patent: May 9, 2017Assignee: CORNING OPTICAL COMMUNICATIONS LLCInventors: Micah Colen Isenhour, James Phillip Luther
