Abstract
PURPOSE: To prevent the change in the relative size of outside diameter and core diameter, shape, etc. and obtain sufficient strength by filling fine glass powder or the like in the spacing between the bundle of fiber base materials and the glass pipe to be put on at the time of stretching.
CONSTITUTION: The sectional shape of each fiber base material 1 is ground to a hexagonal shape and these fiber base materials 1 of a hexagonal shape are so disposed and bundled as to become dense with each other and if there is any spacing between the bundle of the base materials 1 and the quartz glass pipe 3 to be put on at the stretching, the quartz glass rods 5, quartz glass fibers, fine glass powder or the like meeting the shape of the spacing is filled therein at the time of stretching and reducing the diameter of the same, after which while being evacuated from the other end of the closed glass pipe, the stretching and diameter-reducing are done. By filling the filler at the time of stretching and diameter-reducing this multicore fiber from the base materials 1, the change in the relative size of the outside diameter and core diameter, position and shape may be prevented and the sufficient strength may be obtained.
