Abstract
A method of making a multicore optical fiber prefom, the method including heating a sleeve blank above its softening temperature and molding the heated sleeve blank within a mold to form a sleeve so that exterior surfaces of the sleeve assume the shape of the mold, the sleeve being formed of silica-based glass and the sleeve comprising a plurality of core cane holes extending within the sleeve. The method further including inserting a core cane through each of the core cane holes, the core canes being formed of silica-based glass and the core canes each comprising a core region.
