Abstract
Abstract A flexible fiberoptic bundle of light-conducting multifibers wherein each multifiber comprises a plurality of fused together individually glass-clad glass monofilaments having overcladdings of glass along their respective lengths. The overcladdings are removed throughout at least intermediate portions of the lengths of each multifiber in the fused bundle to free corresponding portions of the glass-clad glass monofilaments whereby both the flexibility of the bundle and its resistance to fiber breakage are enhanced.
