OPTICAL FIBER RIBBON, OPTICAL FIBER CABLE, AND INSTALLATION METHOD OF OPTICAL FIBER RIBBON

PROBLEM TO BE SOLVED: To provide an optical fiber ribbon or the like that does not damage the appearance when it is installed and also facilitates the identification of an optical fiber element wire.SOLUTION: Adjacent optical fiber element wires 13a, 13b, 13c, and 13d are intermittently bonded to each other via resin members 15 at a predetermined interval in the longitudinal direction of the optical fiber element wires 13a, 13b, 13c, and 13d. All of the colors of the optical fiber element wires 13a, 13b, 13c, and 13d are the same, and may be white or transparent color same as the color of the wall, ceiling, or the like in the installation place. The lengths of the resin members 15 between the adjacent optical fiber element wires 13a, 13b, 13c, and 13d in the longitudinal direction of an optical fiber ribbon 3 are not constant.SELECTED DRAWING: Figure 1 【課題】敷設した際に美観を損なわず、光ファイバ素線の識別も容易な光ファイバテープ心線等を提供する。【解決手段】隣り合う光ファイバ素線１３ａ、１３ｂ、１３ｃ、１３ｄ同士は、光ファイバ素線１３ａ、１３ｂ、１３ｃ、１３ｄの長手方向に所定の間隔をあけて間欠的に樹脂部材１５により接着される。光ファイバ素線１３ａ、１３ｂ、１３ｃ、１３ｄは、全て同一の色で、敷設される場所の壁や天井などの色と同一の白色や透明色とすることができる。光ファイバテープ心線３の長手方向に対する隣り合う光ファイバ素線１３ａ、１３ｂ、１３ｃ、１３ｄ間の樹脂部材１５の長さは同じではない。【選択図】図１
