ABSTRACT:
A method for splicing optical fibers is provided which is applied to an optical fiber using, as the material of a clad layer, hexafluoroalkyl methacrylate, a residuum of which after pryolysis due to a thermogravimetric analysis is 10% or less by weight. The method comprises a step of removing a protective layer and a cushioning layer at an end portion of the optical fiber, to expose the clad layer, a step of positioning two optical fibers, the end portions of which have been treated, such that the end faces of cores of the two optical fibers are opposed and close to each other, and a step of heating the end portions of the two optical fibers by electrical discharge, to remove the exposed clad layer by pyrolysis and fusion bond the opposed end faces of the cores to each other.
