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 section9has a butt alignment groove portion7to allow at least one pair of optical fibers3to be positioned such that distal ends of optical fibers3mutually but one another. Optical fiber guide sections21on both sides of the butt alignment section9have guide grooves23, 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 section9, and are able to elevate above the butt alignment section9. When fusion splicing at least one pair of the optical fibers3, the optical fiber guide sections21are elevated above the butt alignment groove portions7to allow the optical guides3to be received in the guide grooves23whereupon the optical guide sections21are lowered to cause the distal ends of the optical fibers3to be automatically received in the butt alignment groove portions7.
