Abstract
High strength optical fiber splices are obtained using an inert flowing gas to remove frit and discoloration produced during a fusing process. The fibers being spliced are protected from chemical and particulate contamination by preventing such contaminants from coming into contact with the exposed fiber ends as can occur when the fiber end is place into a solvent to soften the jacket prior to stripping. Finally, a post fusion heat treating step is added after the fibers have been spliced to remove any surface damage that may have been produced.
