Abstract
An optical fiber axial alignment method and related method, and an optical fiber fusion splicing method and related device are disclosed wherein a butt alignment sectionhas a butt alignment groove portionto allow at least one pair of optical fibersto be positioned such that distal ends of optical fibersmutually but one another. Optical fiber guide sectionson both sides of the butt alignment sectionhave guide grooves, whose centers are positioned on substantially straight lines interconnecting centers of at least one pair of opposing butt alignment groove portions formed on the butt alignment section, and are able to elevate above the butt alignment section. When fusion splicing at least one pair of the optical fibers, the optical fiber guide sectionsare elevated above the butt alignment groove portionsto allow the optical guidesto be received in the guide grooveswhereupon the optical guide sectionsare lowered to cause the distal ends of the optical fibersto be automatically received in the butt alignment groove portions
