固体、特に樹脂を用いることが望ましい。However, in these prior arts, since the optical fiber is linearly exposed and housed in the through hole or the organic insulating cylinder, the insulator used in the prior art of (1) is used. Alternatively, when a solid such as a resin is used as the insulating mixture used in the conventional technique of (2), it is directly affected by shrinkage caused when the resin is cured and expansion and contraction of the resin due to a temperature change after the curing. There is a possibility that stress is applied to the fiber, the transmission loss of the optical fiber is increased, and the optical fiber is broken. In order to avoid such problems, it is conceivable to use gas or liquid such as insulating gas or insulating oil as the insulating material or insulating mixture. There is a risk of deterioration. Therefore, as an insulator,
It is desirable to use solids, especially resins.
