Abstract
In a method for fusing splicing optical fibers having different diameters of fiber coating portions, the fiber coating portions of optical fibers to be spliced are clamped on V-groove boards and end faces of the optical fibers are aligned. Then, the end faces of the optical fibers are fused spliced by a discharged heating. An inclination angle &thgr;g of glass fibers of the fusion spliced optical fibers is measured from an observed image of a fusion splicing portion after fusion splicing the optical fibers to estimate a splice loss of the optical fibers.
