PURPOSE:To shorten the time required for fusion shaping and to improve splicing efficiency by making a discharge current at a shaping stage higher than the discharge current at a preliminary heating stage and a pressing stage. CONSTITUTION:The discharge current at the preliminary heating stage and the pressing stage in the fusion splicing method of an optical fiber is set as in the conventional manner, and the discharge current at the shaping stage which is successively performed is set larger than the above discharge current and the time for aligning axes by a self aligning action at the shaping stage is shortened, so that the fusion splicing time of the optical fiber is shortened. Since the discharge current at the shaping stage is made higher, a heating temperature is made high and the speed of the self aligning action of the optical fiber is made high. Thus, not only the time for aligning the axes but also the fusing splicing time are shortened, thereby improving the splicing efficiency. |
