In this case, the lateral pressure applied to the optical fiber increases locally, and the optical fiber may be slightly bent due to the bending of the optical fibers. As a result, there were problems such as increased bending loss and deterioration of extinction ratio due to coiling.

It is an optical fiber with an outer diameter of 200 μm by applying an ultraviolet curable coating to the optical fiber, and 2 has a length of 10 mm and a diameter of 16.5 mm for winding the optical fiber 1.

The coating material 3 is hardened by penetrating the fibers and irradiating it with ultraviolet rays, thereby filling the gaps between the optical fibers 1 with the coating material 3 and forming a smooth surface.

FIG. 1(b) shows a third layer of optical fiber 1 being wound around the coated surface of the second layer.
以上の工程を繰り返して１４層巻き、ずなわら７００回

It showed a low value of 0.5 dB.
