发明名称 DROP-CABLE STRINGING METHOD
摘要 <p>PROBLEM TO BE SOLVED: To provide a drop-cable stringing method that solves such problems as wasting of the cable, the possibility of the loss characteristics of an optical fiber, and the inability of being applied to an existing DV wire. SOLUTION: An optical drop cable 7 is bundled with an existing or newly-laid DV wire (a vinyl drop electric wire) 4, to be draw to a house 10 in the following procedures from an overhead wiring network consisting of a distribution line 1 and a distribution system optical cable 2 laid parallel: The existing or newly- laid DV wire 4 is passed through a pipe 6, formed spirally, and this spiral pipe is arranged over almost the total length of the DV wire 4. Another spiral pipe 6 is jointed for extension, as required. The optical cable 7 is pushed into the one end of the spiral pipe 6 by a wire passing and driving means, that makes wire passing thrust act on the optical drop cable 7 and passed through up to the other end. The pole 3 side end of the optical drop cable 7 passing through the spiral pipe 6 is connected to the distribution system optical cable 2 with a closure 15. Then, the end of the house 10 side is connected to an outdoor optical connection box 11 of the house side.</p>
