Abstract

See full text

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.
