本発明は光電子装置間に接続する、コネクタ付き光ケー
ブルの同一床内布設方法に関す。The present invention relates to a method for laying an optical cable with a connector, which is connected between optoelectronic devices, on the same floor.
光ファイバの伝送特性を長期に亙り維持させるため、引
張，捩，曲げ等のストレスを最小限に抑える補強材料
で、光ファイバを被覆して光ケーブルとしており、その
補強構造により許容値も規定されている。In order to maintain the transmission characteristics of the optical fiber for a long period of time, the optical fiber is coated with a reinforcing material that minimizes stress such as tension, twist, and bending, and the allowable value is also specified by the reinforcing structure. There is.
光多重伝送方式に使用される装置架は、大きく，且つ高
密度実装の架装置で、また、同一床内に複数架列に多数
設置される。The equipment rack used for the optical multiplex transmission system is a large and high-density packaging rack equipment, and a large number of racks are installed in a plurality of rows on the same floor.
この架装置間を接続する、コネクタ付き光ケーブルは、
布設ルートはかなりの曲部を有し、且つ長短あり、この
布設には前記事項に細心の注意を払って作業を行わなけ
ればならず、簡便な布設方法が望まれている。The optical cable with a connector that connects these racks is
The laying route has a considerable curved portion and is long and short, and in this laying work must be performed paying close attention to the above matters, and a simple laying method is desired.
従来の布設方法はリング状に束ねられたコネクタ付きケ
ーブルを解きながら、規定値外の引張，捩，曲げを与え
ないように、接続架装置間の布設を行っていた。In the conventional laying method, while unwinding the cable with a connector bundled in a ring shape, laying between the connecting frame devices is performed so as not to give a tension, a twist, or a bend outside the specified values.
また、布設により生じたケーブル余長は、許容曲げ寸法
以上，捩無しに、リング状に束ねて吸収を行っていた。Further, the excess cable length caused by the installation is absorbed by bundling it in a ring shape without twisting beyond the allowable bending dimension.
しかしながら、従来の布設方法では、 （１） 過度な引張，捩，曲げに対して、布設作業者の
注意力に頼ることが多く、作業の信頼性に欠ける。However, the conventional laying method (1) often depends on the attention of the laying operator against excessive pulling, twisting, and bending, and the work reliability is poor.
（２） 布設終点で生じる余長に対して、これの吸収処
理部を必ず設ける必要がある。(2) It is necessary to provide an absorption treatment section for the extra length generated at the end of installation.
等の欠点があった。There were drawbacks such as.
本発明は、上記問題点の解決を目的とし、リールに巻か
れたケーブルを用い、簡便、且つ無理なく行う、コネク
タ付き光ケーブルの新布設方法を提案するものである。The present invention aims to solve the above-mentioned problems, and proposes a new method of laying an optical cable with a connector, which uses a cable wound on a reel and is performed easily and reasonably.

容部に収容固定させる、本発明のコネクタ付き光ケーブ
ルの同一床用布設方法により解決される。In laying for connecting optoelectronic devices with an optical cable with a connector, an optical cable with a connector having a predetermined length wound around a reel, which has means for reducing and changing the outer diameter of the reel, is used, and one end of the optoelectronic device is used. Hold it on the side,
While rewinding the reel together, a predetermined route is rotatively moved to perform laying, and the extra length generated at the laying end point is left on the reel as it is to be absorbed, and the free outer diameter portion of the reel is reduced to reduce the photoelectron of the other party. This is solved by the method for laying the optical cable with a connector on the same floor of the present invention, in which the optical cable with a connector is accommodated and fixed in the apparatus or a cable accommodation portion in the vicinity thereof.
即ち、リールに巻かれた光ケーブルを、そのまま巻き戻
しながら布設するので、個人人差なく、容易確実に行
え、且つ布設終点での余長処理も簡便となり、目的が達
成される。That is, since the optical cable wound on the reel is laid while being rewound as it is, it can be easily and surely performed without individual differences, and the excess length treatment at the laying end point can be simplified, thereby achieving the purpose.
コネクタ付きケーブルはリールに巻かれて保護されてお
り、布設は、このリールの中心穴に軸を通し、この軸を
持って布設ルートを曳き回すことで行われ、光ケーブル
には過度な引張力や捩を生ぜずに、且つ扱い易く布設出
来る。The cable with a connector is wound on a reel for protection, and the installation is done by passing a shaft through the center hole of this reel and pulling the installation route with this shaft. It can be installed without causing any twist and is easy to handle.
布設の終点で発生する余長の処理は、そのままリールに
巻き戻した状態とし、保護吸収させ、且つリールごと光
電子装置内或いはその近傍のケーブル収容部に収容固定
し、特別の処置部を設ける必要がない。The extra length generated at the end of laying needs to be rewound on the reel as it is, absorbed and protected, and the reel is housed and fixed in the cable housing in or near the optoelectronic device, and a special treatment section needs to be provided. There is no.
また、リールは最大収容長に合わせた外径を有するが、
光ケーブルの布設後は、余長部のみが心部に巻かれ、そ
の巻き外径は小径となり、巻き枠の大部分は無駄な空き
外径部となっている。Also, the reel has an outer diameter that matches the maximum storage length,
After laying the optical cable, only the extra length is wound around the core, the outer diameter of the winding is small, and most of the winding frame is a wasted outer diameter.
そこで、この空き外径部を無くするように、外径部が縮
小可変する手段を備えたリールとしている。Therefore, the reel is provided with means for reducing and changing the outer diameter portion so as to eliminate the empty outer diameter portion.
この可変手段は、例えば、リールの外径に同心に各種径
の断続スリット円を設けておき、所定径のスリット円を
通じさせて、その外周部を切除し外径を縮小させること
により行え、光ケーブルの布設後に余長部を保護するに
必要な部分を残し、外径を縮小させ小形のリールとし
て、取扱，収容し易くさせている。This variable means can be performed, for example, by providing intermittent slit circles of various diameters concentrically with the outer diameter of the reel, allowing the slit circles of a predetermined diameter to pass through, and cutting the outer peripheral portion to reduce the outer diameter. After laying, the portion necessary to protect the extra length is left, and the outer diameter is reduced to make it easier to handle and store as a small reel.
かくして、コネクタ付き光ケーブルの布設において、過

点での余長処理も特別な処置部を設ける必要がなく、そ
のままリールに吸収させ、外径も縮小させて収容方法を
簡便にすることが出来る。Thus, in laying an optical cable with a connector, reliable work can be obtained without giving excessive tension, twist, and bending, and without relying on the attention of the laying work. Moreover, excess length treatment at the end of laying is also possible. It is not necessary to provide a special treatment section, and the reel can be absorbed as it is, and the outer diameter can be reduced to simplify the storage method.
