Description
本発明は、光ファイバケーブルに関し、特に、スロットコアのスロットに光ファイバが収納された光ファイバケーブルに関する。
The present invention relates to an optical fiber cable, and more particularly to an optical fiber cable in which an optical fiber is accommodated in a slot of a slot core.
光ファイバケーブルには、スロットコアに設けられたスロットに光ファイバ心線が収納されているスロット型光ファイバケーブルがある。スロット型光ファイバケーブルに収納される光ファイバ心線としては、光ファイバ同士を接続する時の作業性を向上させるために、複数本の光ファイバ心線を並列に配置し、これを一括被覆した光ファイバテープ心線が多く用いられている。この光ファイバテープ心線は、一括被覆した複数本の光ファイバ心線を一括で融着接続あるいはコネクタ接続することが可能である。
An optical fiber cable includes a slot type optical fiber cable in which an optical fiber core wire is accommodated in a slot provided in a slot core. As optical fiber cores housed in slot type optical fiber cables, in order to improve workability when connecting optical fibers, a plurality of optical fiber core wires are arranged in parallel and covered collectively. An optical fiber ribbon is often used. With this optical fiber ribbon, a plurality of coated optical fibers can be fused or connected together at once.
近年、光ファイバケーブルの高密度細径化の要望が高くなっている。スロット型光ファイバケーブルについても同様の要望がある。スロット型光ファイバケーブルの外径は、そのスロットコアの太さに大きく依存しており、スロット型光ファイバケーブルの細径化を実現させるためにはスロットコアを細くする必要がある。そして、スロットコアの太さは、光ファイバ心線を収納するスロットの大きさに依存しており、スロットを小さくすればスロットコアを細径化することが可能となる。
In recent years, there has been a growing demand for high-density and small-diameter optical fiber cables. There is a similar demand for slot-type optical fiber cables. The outer diameter of the slot type optical fiber cable greatly depends on the thickness of the slot core, and it is necessary to make the slot core thinner in order to reduce the diameter of the slot type optical fiber cable. The thickness of the slot core depends on the size of the slot that accommodates the optical fiber core wire. If the slot is made smaller, the slot core can be made thinner.
しかしながら、図８に示すように、長手方向に同じ箇所でテープ化材が施された光ファイバテープ心線１１１を収納する場合では、スロットの中で積層した光ファイバテープ心線１１１が回転可能である必要があるため、スロット寸法を設計する際に、光ファイバテープ心線１１１を必要枚数積層した際の外接円１４０を描き、その外接円１４０以上のスロットの大きさとする必要がある。この方法ではスロットの大きさが積層した光ファイバテープ心線１１１の外接円１４０と同じ大きさ、若しくは外接円１４０より大きくする必要があり、スロットコア１２０の細径化、ひいては光ファイバケーブルの細径化の足かせとなっている。
However, as shown in FIG. 8, in the case where the optical fiber tape core 111 with the taped material applied at the same position in the longitudinal direction is housed, the optical fiber tape core 111 laminated in the slot can be rotated. Therefore, when designing the slot dimensions, it is necessary to draw a circumscribed circle 140 when the required number of optical fiber ribbons 111 are stacked and to have a slot size larger than the circumscribed circle 140. In this method, the slot size must be the same as or larger than the circumscribed circle 140 of the laminated optical fiber ribbon 111, and the slot core 120 can be reduced in diameter, and the optical fiber cable can be narrowed. This is a drag on diameter.
また、近年、光ファイバケーブルの細径化と同様にケーブル施工性向上の要望が高くなっており、その中で光ファイバケーブルの融着作業容易であることが求められている。上気した光ファイバケーブルの細径化を実現するためだけであれば、光ファイバテープ心線を用いず、単心の光ファイバ素線を用いればスロットコアを細径化することが可能となる。しかしながら、光ファイバ素線を用いた光ファイバケーブルでは、融着作業時に光ファイバテープ心線を用いた光ファイバケーブルと比べて多くの融着時間が必要となってしまい、施工性向上の足かせとなっている。
Also, in recent years, there has been a growing demand for improved cable workability as well as a reduction in the diameter of optical fiber cables, and among them, it is required that the optical fiber cable can be easily fused. The slot core can be reduced in diameter by using a single-core optical fiber instead of using an optical fiber ribbon, only if it is necessary to reduce the diameter of the above-mentioned optical fiber cable. . However, an optical fiber cable using an optical fiber strand requires more fusing time than an optical fiber cable using an optical fiber tape core at the time of fusing work. It has become.
本発明は上記実情に鑑みてなされたものであって、高密度細径化及び施工性向上を実現することができる光ファイバケーブルを提供することを目的とする。

As shown in FIG. 3, the bundle of optical fiber cores 10 includes n optical fiber cores 10 1 , 10 2 ,..., 10 n−1 , 10 n are optical fiber cores 10. The two optical fiber core wires 10 adjacent to each other are fixed and gathered together by the intermittent fixing portions 50 provided intermittently two-dimensionally in the longitudinal direction and the width direction. The intermittent fixing portion 50 is provided with a separation distance so as not to contact adjacently in the width direction of the optical fiber core wire 10.
間欠固定部５０は、図３に示すように、隣接する２心の光ファイバ心線１０を固定するテープ状の部材である。間欠固定部５０が複数設けられる際には、光ファイバ心線１０の長手方向に位置をずらして設けられる。また、間欠固定部５０は、隣接する２心の光ファイバ心線１０の間を上下から紫外線硬化性樹脂あるいは熱可塑性樹脂により固定するものであってもよい。
The intermittent fixing part 50 is a tape-like member that fixes two adjacent optical fiber core wires 10 as shown in FIG. When a plurality of intermittent fixing portions 50 are provided, the positions are shifted in the longitudinal direction of the optical fiber core wire 10. Moreover, the intermittent fixing | fixed part 50 may fix between between the adjacent optical fiber core wires 10 with an ultraviolet curable resin or a thermoplastic resin from the upper and lower sides.
間欠固定部５０で固定された光ファイバ心線１０は、図４に示すように、４心毎に識別糸６０を巻き付けて結束している。識別糸６０は、複数本の光ファイバ心線１０から所望の光ファイバ心線１０を識別するための心線識別性を確保するための識別用の着色糸である。識別糸６０で結束する光ファイバ心線１０の心数は、４本に限られず、２０心乃至４０心毎に巻き付けて結束しても構わない。光ファイバ心線１０を結束及び識別する識別糸６０の代わりに、図５に示すように、識別テープ６２であってもよい。識別テープ６２であれば、着色による識別だけでなく、ドット印刷等を施して識別することも可能となる。
As shown in FIG. 4, the optical fiber core 10 fixed by the intermittent fixing unit 50 is wound by binding the identification yarn 60 every four cores. The identification yarn 60 is a colored yarn for identification for ensuring the core wire distinguishability for identifying a desired optical fiber core wire 10 from a plurality of optical fiber core wires 10. The number of the optical fiber cores 10 bundled with the identification yarn 60 is not limited to four, and may be wound around 20 to 40 cores. As shown in FIG. 5, an identification tape 62 may be used instead of the identification yarn 60 for binding and identifying the optical fiber core wire 10. The identification tape 62 can be identified not only by coloring but also by dot printing.
第１の実施の形態に係る光ファイバケーブル１は、図１（ａ）に示すように、複数の光ファイバ心線１０をスロット２２に収納する場合、スロット２２の中で束状にした光ファイバ心線１０が回転可能である必要があるため、スロット２２の寸法を設計する際に、束状の光ファイバ心線１０を必要心線数で束ねた際の外接円４０を描き、その外接円４０以上のスロット２２の大きさとする必要がある。束状にした光ファイバ心線１０による外接円４０の直径ｄ3は、図２（ａ）に示す。束状にした光ファイバ心線１０による外接円４０の直径ｄ3は、光ファイバ心線１０を密集させた状態である場合に最も細径化した状態になる。
As shown in FIG. 1A, the optical fiber cable 1 according to the first embodiment includes an optical fiber bundled in the slot 22 when a plurality of optical fiber cores 10 are stored in the slot 22. Since the core wire 10 needs to be rotatable, when designing the dimensions of the slot 22, a circumscribed circle 40 is drawn when the bundled optical fiber core wires 10 are bundled with the required number of core wires, and the circumscribed circle is drawn. The size of the slot 22 should be 40 or more. The diameter d 3 of the circumscribed circle 40 by the bundled optical fiber core wire 10 is shown in FIG. The diameter d 3 of the circumscribed circle 40 formed by the bundled optical fiber cores 10 becomes the smallest diameter when the optical fiber core wires 10 are in a dense state.
また、第１の実施の形態に係る光ファイバケーブル１は、複数の光ファイバ心線１０をスロット２２に収納する場合、複数の光ファイバ心線１０が単心単位で動くことが可能であるため、どのような形のスロット形状であってもスロット２２内で動くことが可能である。したがって、スロット２２の寸法は、光ファイバ心線１０が実装可能なスロット面積とすれば良いので、スロット２２の細径化が可能である。
Moreover, since the optical fiber cable 1 which concerns on 1st Embodiment accommodates the some optical fiber core wire 10 in the slot 22, since the some optical fiber core wire 10 can move per single core, it is possible. Any shape of slot shape can be moved within the slot 22. Therefore, the dimension of the slot 22 may be a slot area in which the optical fiber core wire 10 can be mounted, so that the slot 22 can be reduced in diameter.
一方、従来の光ファイバケーブル１００は、図１（ｂ）に示すように、複数の光ファイバ心線１１０を並列に配置し、これを一括被覆した光ファイバテープ心線１１１をスロット１２２に収納する場合、スロット１２２の中で光ファイバテープ心線１１１が回転可能である必要があるため、スロット１２２の寸法を設計する際に、光ファイバテープ心線１１１を必要枚数積層した際の外接円１４０を描き、その外接円１４０以上のスロット１２２の大きさとする必要がある。必要枚数積層した光ファイバテープ心線１１１による外接円１４０の直径ｄ4は、図２（ｂ）に示すように、光ファイバテープ心線１１１を単純に積層させるだけであるので、束状にした光ファイバ心線１０による外接円４０の直径ｄ3と比べると大きくなる。
On the other hand, in the conventional optical fiber cable 100, as shown in FIG. 1B, a plurality of optical fiber cores 110 are arranged in parallel, and an optical fiber tape core 111 covering all of them is accommodated in a slot 122. In this case, since the optical fiber tape core 111 needs to be rotatable in the slot 122, when designing the dimensions of the slot 122, the circumscribed circle 140 when the required number of optical fiber tape cores 111 are stacked is formed. It is necessary to draw and make the size of the slot 122 more than the circumscribed circle 140. As shown in FIG. 2B, the diameter d 4 of the circumscribed circle 140 by the required number of optical fiber tape cores 111 is simply bundled so as to form a bundle. This is larger than the diameter d 3 of the circumscribed circle 40 formed by the optical fiber core wire 10.
第１の実施の形態に係る光ファイバケーブル１では、上述したように束状にした光ファイバ心線１０による外接円４０の直径ｄ3を細径化することができるので、スロット２２を小さく設計することができ、スロットコア２０の細径化をすることができる。また、第１の実施の形態に係る光ファイバケーブル１は、スロットコア２０を細径化することができることによって、従来の光ファイバケーブル１００の直径ｄ2よりも、光ファイバケーブル１の直径ｄ1を細径化することもできる。
In the optical fiber cable 1 according to the first embodiment, the diameter d 3 of the circumscribed circle 40 formed by the bundled optical fiber core wire 10 can be reduced as described above, so the slot 22 is designed to be small. The slot core 20 can be reduced in diameter. Further, the optical fiber cable 1 according to the first embodiment has a diameter d 1 of the optical fiber cable 1 that is smaller than the diameter d 2 of the conventional optical fiber cable 100 by reducing the diameter of the slot core 20. The diameter can be reduced.
また、第１の実施の形態に係る光ファイバケーブル１では、間欠固定部５０が複数設けられる際に、光ファイバ心線１０の長手方向及び幅方向の２次元的に間欠的に設けられていることによって、間欠固定部５０の重なりを防いで光ファイバ心線１０を束ねることができる。このことによって、スロットコア２０及び光ファイバケーブル１の細径化に寄与する。
Further, in the optical fiber cable 1 according to the first embodiment, when a plurality of intermittent fixing portions 50 are provided, they are intermittently provided two-dimensionally in the longitudinal direction and the width direction of the optical fiber core wire 10. Thus, the optical fiber core wires 10 can be bundled while preventing the intermittent fixing portions 50 from overlapping. This contributes to reducing the diameter of the slot core 20 and the optical fiber cable 1.
また、第１の実施の形態に係る光ファイバケーブル１では、光ファイバ心線１０を用いているので、光ファイバ素線を用いた光ファイバケーブルと比べて融着時間が少なくすることができるので、施工性向上を実現することができる。
In addition, since the optical fiber cable 1 according to the first embodiment uses the optical fiber core wire 10, the fusion time can be reduced as compared with the optical fiber cable using the optical fiber strand. Improvement of workability can be realized.
ここで、実施例として、第１の実施の形態に係る光ファイバケーブル１と従来の光ファイバケーブル１００との寸法等の相対値の比較を表１に示す。第１の実施の形態に係る光ファイバケーブル１のスロット２２及び従来の光ファイバケーブル１００のスロット１２２には、それぞれ１００心の光ファイバ心線１０を収納する１００心型の光ファイバケーブルとする。
Here, as an example, Table 1 shows a comparison of relative values such as dimensions of the optical fiber cable 1 according to the first embodiment and the conventional optical fiber cable 100. The slot 22 of the optical fiber cable 1 according to the first embodiment and the slot 122 of the conventional optical fiber cable 100 are 100-core optical fiber cables that accommodate 100 optical fiber cores 10 respectively.
この表１の結果より、スロットコア外径、ケーブル外径、ケーブル質量、スロット幅、スロット深さは、それぞれ第１の実施の形態に係る光ファイバケーブル１が、従来の光ファイバケーブル１００と比して約２０％減少している。また、伝送特性、防水特性等の光ファイバに関する特性は、第１の実施の形態に係る光ファイバケーブル１及び従来の光ファイバケーブル１００の両方共に満たす。つまり、この表１の結果より、第１の実施の形態に係る光ファイバケーブル１は、光ファイバに関する特性を満たしつつ、細径化することができたことを示している。
