能となる。 In this case, since a constant tension is applied to the optical fiber cables 6 by the optical fiber cable connection support device 1 until the adhesive hardens, the optical fiber cables are stretched in a straight line within the case body 10. That will happen. Therefore, the exposed portion of the optical fiber 6a, which has particularly low mechanical strength, does not bend or loosen, and unreasonable stress such as bending or twisting is not applied to the connecting portion. Therefore, it is possible to improve the reliability of the connection portion of the optical fiber cable.

In other words, if a workbench is fixed in front of the heat fusion device that connects optical fiber cables and the workbench is used to perform the above-mentioned work, the next process will be completed after connecting the optical fiber cables. It is possible to not only shorten the time it takes to shift to the next stage, but also improve work efficiency.

小限とすることができる。(2) When the connection part of an optical fiber cable is exposed to temperature changes after it is put into service, distortion may be added to the optical fiber cable due to thermal expansion and contraction, which may cause fluctuations in transmission characteristics. By using this method, the reinforcing member can be cured while the optical fiber cable is held in a straight line, so that the above-mentioned fluctuation in transmission characteristics can be minimized.
(3) 光フアイバケーブル接続部を直線状に保持し
たまま補強部材を硬化させるので、光フアイバ
