摘要： A method for producing a coupler based on fiber-fused connection enabling simple, rapid production of a coupler no matter how many optical fiber core lines may be involved or no matter how small their diameter may be, comprises placing a plurality of optical fiber cords 1, 2 in parallel which comprise optical fiber core lines 3, 4 covered with jackets 7, 8 with resilient fibers 5, 6 inserted between the periphery of the core lines and the jackets; cutting a specified point of the jacket of each optical fiber core line to divide the jacket into two limbs; sliding the divided limbs (9, 9′ and 10, 10′) of the jackets in opposite directions to expose thereby sections of the underlying optical fiber core lines, the exposed sections of optical fibers being brought into contact with each other, and heated to melt to form thereby a fusion-connected section 11; sliding back each jacket limb close to the fusion-connected section; and placing the fusion-connected section 11 together with the inward ends of jacket limbs in a protective case 12, a hardening resin 13 being introduced into the cavity within the protective case 12 to fill the cavity, and the resin being hardened to integrate the optical fiber cords with their connection within the protective case.
