PURPOSE:To connect optical fibers with a piece of a connecting box without using optical cables and to simplify a repair operation by using the connecting box provided with optical fiber holding parts and housing parts on both sides of a shaft in a cylindrical cover. CONSTITUTION:The housing parts 3 for the existing optical fibers and the intervening optical fiber housing parts 2 are provided on both sides of the shaft of the connecting box and the holding parts 1 are provided therebetween. Repair of the cut optical cable is executed by first stripping the damaged part of the cable 10 by about 80cm and winding the intervening optical fiber 7 around the shaft 6. The existing optical fiber 8 is then loosened and is welded to the intervening fiber 7 by a welding machine. The juncture 9 is held in the holding part 1 and the surplus length of the fibers 7, 9 are wound in the housing parts 2, 3 and are fixed by a tape. A cover 4 is mounted to the box. The optical fibers are thus connected with a piece of the connecting box using the optical fibers alone without using optical cables and, therefore, the repair operation is simplified. |
