Abstract
A fusion splicer and fusion splicing method for optical fibers is disclosed including a TV camera which obtains transmitted light images passing through side areas of respective optical fibers an image processing unit which calculates mode field diameters of the respective optical fibers from brightness distributions of the images in terms of directions traverse to the optical fibers to calculate a diametric difference between the mode field diameters, a movable base to move abutted portions between the optical fibers relative to an electric discharge beam position, a drive unit which implements additional electric discharge heating after applying electric discharge fusion splicing heating to the abutted portions while moving the electric discharge beam position toward one of the optical fibers, of which mode field diameter is regarded to be small, and a control unit which controls an electric discharge power supply
