Method for terminating optical fiber cable

Abstract

Abstract PURPOSE:To make sure moisture-proofing treatment of the terminal of an optical fiber cable without damaging the optical fiber cores by inserting protective tubes onto the optical fiber cores, inserting a cylindrical body onto the optical fibers and packing a moisture-proof intimate mixture therein. CONSTITUTION:Sheaths 3 and cable cores 4 at the terminal of the optical fiber cable 1 are first stripped to expose the respective optical fiber cores 2 and tensile bodies 11 by a prescribed length. The protective tubes 5 cut to a prescribed length are respectively inserted onto the cores 2 and after the tubes 5 are adhered and united by an adhesive agent, an adhesive tape 6 is wound around the tubes to approximately the same diameter as the diameter of the cable 1. The cylindrical body 7 is fitted onto the cable 1 and thereafter moisture- proofing intimate mixture 10 is poured from the other end and is packed into the cylindrical body 7. A heat shrinkable tube 8 is finally put on the end of the cylindrical body 7 on the cable 1 side upon curing of the mixture 10 is heated to fix the cylindrical body 7 to the cable 1. The sure moisture-proofing treatment of the cable terminal is thereby executed.
