<p>PROBLEM TO BE SOLVED: To provide a wound optical cable line which consists of an optical cable wound on an overhead ground wire, eliminates the necessity of looping the optical cable at its connection part and, further, protects the optical cable from damage. SOLUTION: At a connection part of optical cables 16, the ends of the optical cables 16 are introduced into a closure 22 to contain connection parts and excessive lengths of optical fiber cores in the closure 22. Further, the closure 22 is attached to a tower detouring wire 18 of an overhead ground line 12. At a position where the optical cable 16 is branched from the overhead ground line 12, the overhead ground line 12 and the optical cable 16 are held by a clamp 34 with a cushion which consists of a clamp main part and a cushion layer provided on the inside of the clamp main part.</p> |
