PROBLEM TO BE SOLVED: To prevent projection and movement in the longitudinal direction of a coated optical fiber in an optical cable post-branch connection part. SOLUTION: This post-branch connection part is provided in the middle part in the longitudinal direction of the optical cable 1 housing the coated optical fiber 14 in a groove 12a of a spacer 13 and provided with a coat on its outside, and the cost of a prescribed length is removed without cutting out the spacer 13, and the spacer 13 is exposed, and a part of the coated optical fiber 4 is taken out from the inside of the groove of the spacer to be cut out in a spacer exposed part 2, and is connected to the coated optical fiber 6 of a branching optical cable 5, and the connection part between the spacer exposed part 2 and the branching optical cable is housed in a connection box 9. In such a case, the part of the length of at least 1/2 or above of the spacer exposed part 2 is coated by pressing winding 3. |
