なかった。Problems to be Solved by the Invention However, with the above configuration, microcracks or breaks occur in the optical fiber at the boundary between the solder and the adhesive due to the difference in thermal expansion coefficients between the solder, the resin adhesive, and the optical fiber. In particular, reliability in the low temperature range (-16°C or lower) could not be obtained.

などの損傷を受けることがない。Means for Solving the Problems Therefore, the present invention aims to reduce the thickness of the solder for fixing the strands of optical fibers as much as possible, and to apply a rubber-like adhesive over a wide temperature range to the adhesive for fixing the core fibers of optical fibers. An elastic material is used to minimize the stress applied to the optical fiber due to changes in ambient temperature, thereby preventing the optical fiber from being damaged by microcracks or breakage. If the thickness of the bonder that fixes the core part of the optical fiber is made thinner, and if the adhesive that fixes the core part of the optical fiber is made of rubber-like elastic material over a wide temperature range, it is possible to reduce the amount of light caused by temperature changes (particularly in the low temperature range). Since the stress on the fiber becomes slight, the optical fiber does not suffer damage such as microcracks or breakage.
