Containment in optical fiber fuse manner and optical fiber

摘要

PROBLEM TO BE SOLVED: To solve the problem that an optical fiber can not uniformly be heated if a discharge arc deforms.;SOLUTION: An optical fiber fusion splicer, which is equipped with a holder which holds optical fibers so that their end parts face each other and discharge electrodes which generate a discharge arc for fusing and splicing the end parts of the held optical fibers and fuses and splices the optical fibers with the discharge arc generated between the discharge electrodes, is equipped with a reduction member which reduces deformation of the discharge arc by towing the discharge arc below or by the discharge arc, or below and above it by deforming the distribution of an electric field and a magnetic field around the discharge arc. Further, the splicer is equipped with the discharge electrodes opposite each other horizontally or vertically, equipped with a rotary support base which can switch the direction wherein the discharge electrodes face each other between the horizontal and perpendicular, or a level which can measure the horizontality or perpendicularity of the discharge electrodes to reduce deformation of the discharge arc, so that the optical fibers can be fused and spliced.;COPYRIGHT: (C)2004,JPO
