In the case of a single-core optical fiber, it can be fixed to the optical fiber holding component of the present invention by using a plurality of optical fibers.

FIG. 2A is a perspective view showing a state in which an eight-core tape-shaped optical fiber is fixed to the optical fiber holding component described with reference to FIG. In fixing the tape-shaped optical fiber to the optical fiber holding component, the tape coating, which is the jacket of the tip portion of the tape-shaped optical fiber, is peeled off, and the coating of the exposed core is removed to expose the optical fiber. This optical fiber is inserted along the V-groove 1a from the outer mounting portion 1b side. Along with the insertion, the optical fiber is advanced through the gap between the temporary positioning portion 2a and the V-groove 1a, and the jacket portion 4b of the tape-shaped optical fiber is placed on the jacket placement portion 1b. As shown in FIG. 2B, the provisional positioning portion 2

The two tape-shaped optical fibers are mounted on the outer mounting portion so as to be shifted in the lateral direction by substantially half of the core wire interval. Therefore, the upper optical fiber enters between the lower optical fibers of the tape-shaped optical fiber. For example, an optical fiber holding component is formed by arranging two 8-core tape-shaped optical fibers each having an outer diameter of an optical fiber of 125 μm, a protective coating having a thickness of 62.5 μm, and covering with a jacket. When an optical fiber array is configured by fixing the optical fiber array to the optical fiber array, 16 rows of V grooves are formed at 127 μm intervals.

The optical fiber strands arranged in the grooves are not arranged alternately as described with reference to FIG. 6C, but are arranged left and right. Therefore, even if the outer sheath portions of the left and right tape-shaped optical fibers are placed adjacent to each other on the outer sheath mounting portion, the distance between the optical fiber strands inside both the tape-shaped optical fibers is within the tape-shaped optical fiber. Is larger by twice the thickness of the jacket portion than the core wire interval, and the optical fiber inserted into the V-groove is bent. In order to reduce the bending, the distance between the front end of the jacket portion and the rear end of the V-groove may be increased.
