Abstract

PURPOSE:To lay an optical fiber cable without the loss of its characteristics even if the mechanical strength is small by passing a guiding conduit member through a conduit line, leading the optical fiber cable into the guiding conduit member and then pulling out only the guiding conduit member. CONSTITUTION:After previously inserting two leading-in wires 2, 2' for a guiding conduit member and an optical fiber cable into a conduit line 1, the leading-in wire 2' is connected to the guiding conduit member 5 and the leading line 2 is inserted into the conduit member 5 to lead the conduit member 5 into the conduit line 1 through the leading-in wire 2'. One end P of the guiding conduit member 5 is fixed to constitute a cable leading-in wire in the conduit line 1 through the conduit member 5 by applying tension to the other end. Then a cable 13 is connected with the leading-in wire 2' and the cable 13 is led in the conduit member 5. Finally, the guiding conduit member 5 is pulled out after laying the conduit line, so that the optical fiber cable 13 can be precisely and stably laid in the conduit line 1.
