Definitions
- the present invention relates to an optical fiber tape, a method for manufacturing the optical fiber tape, and an ultraviolet curable resin composition used for forming a connection portion of the intermittently fixed optical fiber tape.
- Patent Document 1 describes an optical fiber tape (intermittently fixed type optical fiber tape) in which a plurality of optical fibers are connected in parallel and intermittently connected.
- Patent Documents 2 and 3 describe a method for manufacturing such an intermittently fixed type optical fiber tape. Specifically, in Patent Documents 2 and 3, a curable resin is applied between adjacent optical fibers, and an uncured curable resin is dammed up so as not to be connected between optical fibers (separating part). It is described that an intermittently fixed type optical fiber tape is manufactured by curing a curable resin before forming an optical fiber and collecting optical fibers.
- An object of the present invention is to form a connection portion and a non-connection portion of an intermittently fixed type optical fiber tape as designed.
- a main invention for achieving the above object is an intermittently-fixed optical fiber tape having a plurality of optical fibers arranged in parallel and having intermittently arranged connecting portions for connecting two adjacent optical fibers.
- the connecting portion is formed by curing an ultraviolet curable resin containing a siloxane structure in the molecule.
- the connecting portion and the non-connecting portion of the intermittently fixed type optical fiber tape can be formed as designed.
- FIG. 1A is a perspective view of an intermittently fixed optical fiber tape 1.
- 1B is a cross-sectional view taken along the line AA in FIG. 1A.
- FIG. 2A is an explanatory diagram of a production apparatus (tape production apparatus) for the intermittently fixed optical fiber tape 1.
- FIG. 2B is an explanatory diagram of the concentration of the optical fiber 3 after application of the linking agent 9.
- 3A and 3B are explanatory diagrams of the influence of the viscosity reduction of the linking agent 9.
- An intermittently fixed type optical fiber tape having a plurality of optical fibers arranged in parallel and having a connecting portion for intermittently connecting two adjacent optical fibers, the connecting portion having a siloxane structure in the molecule
- the intermittently fixed optical fiber tape is characterized by being formed by curing the ultraviolet curable resin contained in. According to such an intermittently fixed type optical fiber tape, the connecting portion and the non-connecting portion can be formed as designed.
- the ultraviolet curable resin preferably contains a urethane oligomer containing the siloxane structure. According to such an intermittently fixed type optical fiber tape, the connecting portion and the non-connecting portion can be formed as designed.
- the ultraviolet curable resin preferably contains a reactive monomer containing the siloxane structure. According to such an intermittently fixed type optical fiber tape, the connecting portion and the non-connecting portion can be formed as designed.
- a method of manufacturing an intermittently fixed type optical fiber tape having a plurality of optical fibers arranged in parallel and having a connecting portion that connects adjacent two optical fibers intermittently disposed between the optical fibers A step of applying an ultraviolet curable resin containing a siloxane structure in the molecule; a step of removing a part of the ultraviolet curable resin applied between the optical fibers; and an ultraviolet ray on the ultraviolet curable resin between the optical fibers. And the step of forming the connecting portion is clarified. According to such a manufacturing method, the connection part and non-connection part of an intermittently fixed type optical fiber tape can be formed as designed.
- An ultraviolet curable resin composition used for forming the connecting portion in an intermittently fixed optical fiber tape in which connecting portions for connecting two adjacent optical fibers are intermittently disposed, and includes a siloxane structure in the molecule The ultraviolet curable resin composition characterized by this will become clear. According to such an ultraviolet curable resin composition, the connection part and non-connection part of an intermittently fixed optical fiber tape can be formed as designed.
- FIG. 1A is a perspective view of an intermittently fixed optical fiber tape 1.

Abstract
Description
<間欠固定型光ファイバテープの構成>
図1Aは、間欠固定型光ファイバテープ1の斜視図である。図1Bは、図1AのA-A断面図である。
以下の説明では、図1Aに示すように、各方向を定義する。光ファイバテープ1を構成する光ファイバ3に平行な方向(光ファイバ3の光軸方向)を「長手方向」と呼ぶことがある。また、光ファイバテープ1を構成する複数の光ファイバ3の並ぶ方向を「テープ幅方向」と呼ぶことがある。
図2Aは、間欠固定型光ファイバテープ1の製造装置(テープ製造装置)の説明図である。図2Bは、連結剤9の塗布後の光ファイバ3の集線の説明図である。テープ製造装置は、塗布部と、除去部と、光源とを有する。
上記の除去部では、回転刃が回転しながら紫外線硬化樹脂を除去(切断)している。このとき、回転刃からの剪断力によって、液状の連結剤9の粘度が低下するおそれがある
連結剤9の除去時に連結剤9の粘度が低下してしまうと、図3Aに示すように連結剤9を除去して分離部を形成しても、図3Bに示すように分離部が繋がってしまうおそれがある。つまり、連結剤9の粘度の低下によって、連結剤9によって連結された領域が濡れ広がるおそれがある。このように分離部(連結剤9を除去した部分)が繋がってしまうと、間欠固定型光ファイバテープ1の連結部5の長さ(図1Aの長さL1)が長くなる。この結果、光ファイバテープ1から単心の光ファイバ3を分離するときに、大きな力(連結部5を破壊する力)が必要になってしまい、光ファイバ3の損傷が起こって作業性を悪化させたり、ケーブル化後のファイバの歪みや光損失の増大を招いたりする可能性がある。
