Abstract

PURPOSE:To secure the strength and low-loss state of a connection part by forming an internal covering layer of silicone rubber, etc., and an external covering layer of plastics, formed by transfer molding, around the outer circumference of an optical fiber connection part for communication. CONSTITUTION:Primary covering layers 2 and secondary covering layers 3 at the outer circumferences of butt end parts 4 and 4 of optical fibers 1 and 1 are removed to the prescribed length, and the end parts 4 and 4 are butted together to be connected by being melt-stuck. The outer circumference of a connection part 5 including the butted end parts 4 and 4 is coated with silicone rubber, etc., having a low Young's modulus to form an internal covering layer 6 to about 5-50mum thickness, and on the layer 6, an external covering layer 7 having an external diameter equal to that of the layer 3 and a high Young's modulus is formed by transfer molding by using a plastic material compatilbe with the layer 3. In this constitution, the melt- sticking part of the butt end parts 4 and 4 has no small corvature and the deterioration of transmission characteristics is prevented. The layers 7 and 3 are bonded in one body securely, and mutual operation with the layer improves mechanical strength against breaking.
