Optical fiber bundle, optical connection structure, and method for manufacturing optical fiber bundle
By employing a multi-layered resin structure in the fiber bundle, including a first resin layer, a second resin layer, and a third resin layer, with spacing between them, the influence of resin expansion and contraction on the optical fiber is resolved, improving the tensile strength and stability of the optical fiber and enhancing the structural rigidity of the fiber bundle.

AI Technical Summary
In the prior art, the resin part of the optical fiber expands and contracts when the temperature and humidity change, which causes force to be applied to the optical fiber and may cause the optical fiber to break. Moreover, the larger the volume of the resin part, the greater the force applied, which affects the tensile strength of the optical fiber.
The structure employs a multi-layered resin section, comprising a first resin section, a second resin section, and a third resin section. The third resin section is separated from the inner surface of the second optical fiber receiving section. The optical fiber is fixed by an adhesive to form the first optical fiber receiving section and the second optical fiber receiving section. This reduces the impact of resin section expansion and contraction on the optical fiber and ensures the tensile strength of the optical fiber.
It effectively reduces the force exerted on the optical fiber by the expansion and contraction of the resin, improves the tensile strength of the optical fiber, enhances the stability and rigidity of the optical fiber bundle, and reduces the risk of optical fiber breakage caused by resin expansion and contraction.
