Abstract
The method of making an optical fiber bundle ( ) from individual optical fibers with good optical properties and a wider applicability includes temporarily mechanically holding individual optical fibers together and pushing them in a snug fit in a single metallic sleeve ( ) made from a metallic material that has a sufficient high temperature strength at a forming temperature of the optical fiber glass; installing the optical fiber bundle ( ) in a clamping device ( ) in order to hold the optical fiber bundle fixed in an axial and radial direction; heating the end of the clamped optical fiber bundle ( ) to the forming temperature, pressing the single metallic sleeve ( ) on the optical fiber bundle and compressing the end of the optical fiber bundle in the single metallic sleeve with a forming tool ( ) to shape or form the individual optical fibers in a hexagonal packing; cooling the shaped end of the optical fiber bundle ( ) and removing the optical fiber bundle from the clamping device ( ). The invention also includes the resulting optical fiber bundle and an apparatus for performing the method.
