Abstract
A device for fusion splicing, by an arc discharge, a pair or a plurality of pairs of optical fibers arranged so that end surfaces thereof face each other. An optical fiber arrangement portion positions the pair or the plurality of pairs of optical fibers between a pair of electrodes. A control portion controls a voltage applied to the pair of electrodes. The control portion generates a first discharge between the pair of electrodes, stops the first discharge between the pair of electrodes, and then generates an arc discharge between the pair of electrodes to fusion-splice the pair or the plurality of pairs of optical fibers to each other. A discharge time of the first discharge is 200 milliseconds or less. A time from stopping the first discharge to starting the arc discharge is 100 milliseconds or less.
