The fiber had to be pulled indoors.
敷設管路に沿わせる場合、 配管経路によってはすでに他の電線が空間を占有し ているため光ファイバ設置のスペースがない、 配管の曲率半径が小さく曲がりが きついため光ファィバの伝送特性に影響を与えるなどの理由により光ファイバを 引き込めないことがある。 通気口や配管口を利用する場合、 屋内に敷設した光フ アイバが壁から突出し美観上好ましくなく、 また光ファイバが露出しているため 使用中に光フアイバを破損する恐れがあつた。  When laying along an installed pipeline, there is no space for installation of optical fiber because other wires already occupy space depending on the piping route, and the radius of curvature of the pipe is small and the bend is tight, affecting the transmission characteristics of the optical fiber. The optical fiber may not be able to be pulled in for reasons such as giving. When using vents and pipe openings, optical fibers laid indoors protrude from the wall, which is not desirable from an aesthetic standpoint, and the optical fibers are exposed, which may damage the optical fibers during use.
