REINFORCING STRUCTURE OF FUSION SPLICING PART OF OPTICAL FIBER CORDS AND METHOD OF REINFORCING

摘要

PROBLEM TO BE SOLVED: To easily process right and left tension fibers which are easily separated when optical fiber cords including tensile strength fiber are connected. SOLUTION: A fusion splicing part of fibers 3 of coated optical fibers 2 of right and left optical fiber cords 1A and 1B is covered with a fusion reinforcing sleeve 7, and further the sleeve 7 is covered with a reinforcing tube 11. A first heat shrinkable tube 13 covering the optical fiber cord 1A is slid to the right and one of the tensile strength fibers 5 is held along the outer periphery of the reinforcing tube 11. A second heat shrinkable tube 14 covering the other optical fiber cord 1B is likewise slid to the left and the other of the tension fibers 5 is held along the outer periphery of the reinforcing tube 11. The right and the left tensile strength fibers 5 are made contact with each other and fixed on the both sides of the heat shrinkable tubes 13 and 14. The easily separated tensile strength fibers are easily integrated only by sliding the right and the left heat shrinkable tubes 13 and 14. COPYRIGHT: (C)2005,JPO&NCIPI
