Disclosed is an optical fiber connector for connecting an optical fiber cable including a cable core, an inner coating layer formed on the cable core, and an outer coating layer formed on the inner cable layer. The optical connector includes a ferrule to which the cable core is inserted, a first cable fixing member for fixing the inner coating layer, a second cable fixing member for fixing the outer coating layer, a connector cover having an opening, and a fastening ring provided at an outer circumference of the opening, and formed together with the connector cover as a single body. The fastening ring is fastened after the first and second cable fixing members are fitted into the opening.

Optical fiber connector

Optical connector with molded-on resin boot covering distal ends of

An optical connector comprises an optical fiber cable including a nylon-coated fiber, a tension member thereon, a sheath covering the nylon-coated fiber and the tension member, a ferrule provided at the distal end of the optical fiber cable so as to be attached to the distal end of the nylon-coated fiber, and a holder having a distal end restricted in position by the ferrule when mounted on the nylon-coated fiber. The optical connector is constructed so that the holder is mounted on the nylon-coated fiber by after-attachment. A method for assembling the optical connector comprises providing an urging spring fitted on the nylon-coated fiber so as to be interposed between the ferrule and the holder so as to urge the ferrule forward, and providing a gripper attached to the rear portion of the holder. In this method, the holder is formed of a split body such that the holder is mounted on the nylon-coated fiber by after-attachment after the ferrule is mounted on the distal end of the fiber and the spring is then fitted on the rear portion of the ferrule.
