OPTICAL FIBER FUSION SPLICING DEVICE, AND FUSION SPLICING METHOD FOR OPTICAL FIBER

WIPO Patent Application WO/2020/246576

A1

This optical fiber fusion splicing device fusion splices together, via arc discharge, a pair or a plurality of pairs of optical fibers that are arrayed with the end faces thereof abutting one another. This device comprises a pair of electrodes, an optical fiber disposition unit, and a control unit. The pair of electrodes generate the arc discharge. The optical fiber disposition unit positions the pair or plurality of pairs of optical fibers between the pair of electrodes. The control unit controls the voltage applied to the pair of electrodes. The control unit generates a first discharge between the pair of electrodes, and stops the first discharge between the pair of electrodes, after which the control unit generates an arc discharge between the pair of electrodes to fusion splice the pair or plurality of pairs of optical fibers together. The discharge time of the first discharge is 200 milliseconds or less. The time from the stopping of the first discharge to the starting of the arc discharge is 100 milliseconds or less.
