Claims

[Scope of utility model registration request]

On each connection end side of the pair of coated optical fibers, a concave-convex coating layer is formed by a concave portion where a part of the coating layer is removed along the longitudinal direction and the remaining part, and each concave-convex coating The metal ferrule has an optical fiber protruding from the layer end, has an outer diameter approximately equal to that of each coated optical fiber coating layer, and is to be attached to the connection end of each coated optical fiber.
A concavo-convex fitting part corresponding to the concavo-convex coating layer is formed on the base end side of these, and an insertion hole for the optical fiber is formed in the axial center of the ferrule, and each ferrule receives the coating light. These coated optical fiber connection ends with ferrules are fitted and adhered to the outer periphery of the connection ends of the fibers, and the connection ends of the coated optical fibers with ferrules are butted against each other, the optical fibers are aligned with each other, and the optical fibers and the ferrules are fusion-spliced with each other. Coated optical fiber connection.
