| 摘要 |
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 section 9 has a butt alignment groove portion 7 to allow at least one pair of optical fibers 3 to be positioned such that distal ends of optical fibers 3 mutually but one another. Optical fiber guide sections 21 on both sides of the butt alignment section 9 have guide grooves 23, 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 9, and are able to elevate above the butt alignment section 9. When fusion splicing at least one pair of the optical fibers 3, the optical fiber guide sections 21 are elevated above the butt alignment groove portions 7 to allow the optical guides 3 to be received in the guide grooves 23 whereupon the optical guide sections 21 are lowered to cause the distal ends of the optical fibers 3 to be automatically received in the butt alignment groove portions 7.
