Abstract
A method for fusion-splicing optical fibers and a fusion splicer are provided, which enable preventing a fusion spliced portion from disconnecting when the optical fiber is removed from the fusion splicer. A fusion-splicing method for optical fibers comprises: holding optical fibers and on optical fiber holding parts respectively provided on a pair of movable stages; butting ends of optical fibers by bringing the pair of movable stages mutually closer; fusion-splicing butted optical fibers to form a fusion spliced portion S; carrying out a proof test, the proof test including applying a tension to the fusion spliced portion S by moving the pair of movable stages so as to distance them from each other; and bringing the pair of movable stages mutually closer by a predetermined distance upon completion of the proof test.
