    • A method of fusion-splicing optical fibers having different mode field diameters or small mode field diameters is provided, which method is advantageous in that the splicing loss is smaller. The method comprises a fusion splicing process in which fusion splicing is performed by butting end faces of two optical fibers together and a heat treatment process in which the fusion spliced part of the optical fibers and the vicinity thereof are heated. The heat treatment process is performed by moving an arc heating unit in a direction other than the Y-axis direction (a direction perpendicular to the Z-axis direction and the opposing direction of arc electrodes) and Z-axis direction (the axial direction of the optical fiber), via the fusion spliced part in a Y-Z plane formed by the Y-axis direction and Z-axis direction.
    • 提供了具有不同模场直径或小模场直径的熔接光纤的方法,该方法的优点在于拼接损耗较小。 该方法包括熔接过程,其中通过将两根光纤的端面对接在一起进行熔接,并且加热熔接了光纤的一部分及其附近的热处理工艺。 通过使电弧加热单元沿除了Y轴方向(与Z轴方向垂直的方向和电弧电极的相反方向)以及Z轴方向(轴方向 光纤)经由Y轴方向和Z轴方向形成的YZ平面中的熔接部分。

    • An object is to provide an optical fiber fusion splicing method in which splice loss can be reduced, and also to provide an arc-heating unit used for heating the fusion spliced part of an optical fiber. The method comprises a process of fusion-splicing together the end faces of two optical fibers and a process of continuously heating the fusion spliced part by arc while moving one pair of electrodes provided opposite to each other across the fusion spliced part. The arc heating process is performed with the operation for decreasing arc temperature. The operation for decreasing arc temperature may be achieved by flowing a gas having a molecular weight greater than the average molecular weight of air into a gas atmosphere in which arc heating is performed, or by adding a modulation to an electric discharge current such that the maximum value becomes equal to or more than an electric current for starting arc discharge and the minimum value becomes more than zero and less than the electric current for starting arc discharge.
    • 本发明的目的是提供一种可以减少接头损耗的光纤熔接方法,并且还提供用于加热光纤的熔接部分的电弧加热单元。 该方法包括将两根光纤的端面熔接在一起的工序和通过电弧连续地加热熔接部的工序,同时使跨接在熔接部上的彼此相对设置的一对电极移动。 通过降低电弧温度的操作进行电弧加热处理。 降低电弧温度的操作可以通过将分子量大于空气的平均分子量的气体流入进行电弧加热的气体气氛中,或通过向放电电流添加调制,使得最大值 值变为等于或大于开始电弧放电的电流,并且最小值变得大于零并且小于用于开始电弧放电的电流。
