Abstract
An optical fiber splicing method is provided for largely reducing an optical loss in a splice and eliminating a varying outer diameter and bending deformation. This splicing method splices opposing end faces of two optical fibers by fusion, and heats a formed fusion splice to match mode field diameters of the two optical fibers in the fusion splice, wherein the two optical fibers are fixed with an axial tension applied or not applied to the fusion splice, after the formation of the fusion splice, before the fusion splice is heated.
