Abstract

PURPOSE:To realize a connection part which has superior flexibility, and tensile strength, side-pressure resistance and watertightness, by providing a body of tensile strength in the center of a pressure-tight cylindrical pipe obtained by winding a narrow plate spirally and closely. CONSTITUTION:A narrow plate is wound spirally and closely to form pressure- tight cylindrical pipe 14 with flexibility, in which center body 18 of tensile strength is run; and optical fiber cores 12 and 12' are passed through grooves 19a of retaining metallic fittings 19 and then connected, and core connection parts 13, excessive connection length processing parts 12a and 12a', and body 18 of tensile strength are arranged at the external circumference. After metallic fittings 19 are equipped and fixed to both ends of body 18 of tensile strength, retaining metallic fittings 16 for tensile strength wires are fixed to metallic fittings 19, and tensile strength wires 15 of optical fibers 11 and 11' are fixed to metallic fitting 16 to complete the assembly. Consequently, the cores are not applied with tensile force direct and the steep curvature of the cable is prevented, so that the connection part superior in flexibility can be obtained.
