関する。[Detailed description of the invention] "Industrial field of application j The present invention is a system in which a plurality of multi-core fibers are integrated, and the multi-core fibers can be divided into terminals and branched as necessary during use. This invention relates to split-type optical fiber tapes that are used for processing.

案されている。``Problems to be Solved by the Invention'' Today, as a bidirectional transmission system in a subscriber system, an idea has been proposed in which transmission and reception are performed using two separate fibers.
ところが、上記第７図の構造のテープファイバを用いて
この双方向伝送方式を行なおうとすると、分岐に際して

可能であった。However, when attempting to carry out this bidirectional transmission method using a tape fiber having the structure shown in FIG. This was not possible with this structure.
さらに、１本のファイバ心線２は、その径が通常０．２
５ｎ＋Ｉ１１と極めて細いため、１本づつに分離される
と取り扱い上不都合が生じやすいという問題もあった。Furthermore, the diameter of one fiber core 2 is usually 0.2
Since it is extremely thin (5n+I11), there is also the problem that it is easy to handle it if it is separated one by one.

然に１本のファイバ心線より太いので取り扱い易く都合
が良い。Therefore, if a structure is made of a plurality of bundled coated fibers, for example, two-core fibers, and the whole is coated in parallel, it is easy to separate each unit. The two-fiber core wire coated at once is naturally thicker than a single fiber core wire, so it is convenient to handle.
「課題を解決するための手段」

一体化することにより、上記問題点の解決を図った。"Means for Solving the Problems" The present invention provides a structure of a split optical fiber tape that can be easily separated into individual units, and is a multi-layer optical fiber tape in which a plurality of optical fibers are collectively coated with an ultraviolet curable resin. The above-mentioned problem was solved by integrating the core fibers using an ultraviolet curable resin having a Young's modulus of 5 kg/am'' or more at the highest temperature of actual use of this optical fiber tape.
分割型光ファイバテープの実使用最高温度とは、この光
ファイバテープを使用する環境で予想される温度の最高
値で、通常は６０℃程度である。The maximum actual operating temperature of a split optical fiber tape is the maximum temperature expected in the environment in which this optical fiber tape is used, and is usually about 60°C.

き伝送損失が増大する事故が多発する。The Young's modulus of the integrally molded material at the highest temperature of actual use is 5k.
g/ff1l11'', accidents frequently occur in which transmission loss increases when used.

成形材は、常温（約２０℃）における破断伸びが２０％
以上のものであることが望ましい。Furthermore, the integrally molded material used in the split optical fiber tape of the present invention has an elongation at break of 20% at room temperature (approximately 20°C).
The above is desirable.

ｍｓ″を示した。The reason why UV-curable resins with an elongation at break of less than 20% are unsuitable for use in integrally molded materials is that if the elongation at break is less than this value, the integrally molded material becomes too loose, and the bonded parts made of the integrally molded material may break during handling. This is because there is a risk of an accident in which the multi-core fibers are broken and separated in some places. Incidentally, as the Young's modulus increases, the elongation at break tends to decrease; in the UV-curable resins tested by the present inventors, one with an elongation at break of 20% had a Young's modulus of approximately 80 kg/

In addition, the ultraviolet curable resin that coats this multi-core fiber has a Young's modulus of 40 to 40 at room temperature.
A material weighing about 60 kg/II" is preferably used.

た光ファイバに不規則な曲がりが発生することがない。"Function" The split type optical fiber tape of the present invention has a Young's modulus of 5 kg/l.
Since the multi-core fiber cores are bonded and integrated using l1l11' ultraviolet curable resin, the appropriate tape shape is maintained stably even when the temperature of the usage environment rises, and irregularities in the integrated optical fibers are maintained. No bending occurs.

This can prevent the occurrence of an accident in which the optical fiber core wires are separated unnecessarily.

に戻った後も残留していた。As can be seen from the results in Fig. 2, split optical fiber tapes (Nos. 4 to 7) using an ultraviolet curable resin with an intended Young's modulus of 5 kg/1 m'' or more at 60°C as the integrally molded material 8 were used.
) shows no increase in loss even at high temperatures (60°C). On the other hand, the Young's modulus of the integrally molded material 8 is 5 kg/
Those using resins less than nv' (Nos. 1 to 3) have increased loss at high temperatures, and this increased loss occurs at room temperature (20°C).
It remained even after returning to .

同志が傾いて接合した部分が多く発生しており、これが
伝送損失の増加を招く原因になっていると考えられる。Next, in order to elucidate the cause of this increase in loss, we observed the split optical fiber tape after the heat cycle test. Optical fiber tape Nos. 1 to 3 with increased loss include:
As shown in FIG. 3, adjacent multi-core fiber cores 5.5
There are many parts where the comrades are joined at an angle, and this is considered to be the cause of the increase in transmission loss.

原因は、つぎのように推測される。In this way, the optical fiber tape N after the heat cycle test
The reason why there are parts where the core wires 5, 5 are joined in an inclined manner in 1 to 3 is presumed to be as follows.

ァイバ心線５．５はそれぞれもとの状態に再び変形しよ
うとする。First, since the multicore fiber core wire 5.5 is flat, deformation in the torsion direction is likely to occur when it is manufactured. This deformation is corrected when the multicore fiber cores 5.5 are integrated. However, when the optical fiber tape is exposed to a high temperature environment and the integrally molded material 8 softens, each of the integrated multi-core fiber cores 5.5 tends to deform again to its original state.
そして、多心ファイバ心線５．５は、相互に作用を及ぼ
し合い、その結果互いに傾いて接合する部分が生じ、光
ファイバテープ全体には複雑な変形が生じる。The multi-core fibers 5.5 interact with each other, and as a result, some parts of the optical fiber tape are joined at an angle, resulting in complex deformation of the optical fiber tape as a whole.

られたものである。(Example 2) A four-core, two-split optical fiber tape having the structure shown in FIG. 4 was manufactured using an integrally molded material 8 having the physical properties shown in Table 2. This split type optical fiber tape has release thin film layers 9, 9 provided between the multi-core fiber core 5.5 and the integrally molded material 8.

に心線５．５が分離する事故を防止できる。As can be seen from the results shown in Table 3 in the twisting test below, taking into account the handling of blank space and the formation of bundled cables, an ultraviolet curable resin with a breaking elongation of 20% or more at room temperature should be used for the integrally molded material 8. Accordingly, it is possible to prevent an accident in which the core wires 5.5 are unnecessarily separated when handling the optical fiber tape.
