PURPOSE:To facilitate fusion splicing by setting the axes of optical fibers to be connected on the plane perpendicular to the straight line passing the front ends of a pair of discharge electrodes disposed to face each other and placing the ends of the optical fiber to be connected in the position nearest said straight line so as to face each other. CONSTITUTION:The front ends of the discharge electrodes 2 are formed to a circular conical or pyramidal shape. Fusion splicing is executed by heating the optical fibers 1 in the position deviated from the discharge region. The optical fibers 1 are heated as a result of the heat radiation r heat transmission from this discharge region. Although the axes of the optical fibers 1 are placed on the plane bisecting the segments connecting the front ends of both the discharge electrodes, said axes may be placed in proximity to the one electrode. Then, discharge plasma is generated on the surface of the front ends of the electrodes as well and, therefore, the controllability of heating is much higher than the heating by a heater consisting of a heating wire and the fusion control is facilitated. |
