Abstract
An insert or sleeve is fabricated from a glass-like material as a mica-filled glass and is of a longitudinal tubular configuration having a flat front surface with an aperture for accommodating a glass optical fiber. The aperture is coextensive with a fiber accommodating channel in said insert. The insert is surrounded and anchored into an outer plastic ferrule and a fiber when accommodated in said channel is broken at said surface which surface and fiber face are then polished to assure an optically smooth and polished fiber face which is free from debris damage during polishing.
