Definitions

  • the invention relates to an optical fiber residual length stability control device in an optical cable loose tube.
  • the long length is the phenomenon that the shrinkage of the cable loose tube is cooled and crystallized, and the length is inconsistent with the length of the optical fiber.
  • the remaining length is one of the problems that need to be solved in the production process of the optical fiber cable, which directly affects the high frequency signal.
  • Transmission quality in fiber The traditional process is that the fiber secondary coated loose tube is cooled by the water tank, directly from the tractor to the closing (see Figure 1). During the cooling process of the loose tube, the friction between the water and the loose tube material causes the loose tube to generate internal stress and The tendency of the molecule (retraction) causes an excessive excess length of the fiber relative to the loose tube, which affects the quality of the fiber product.
  • the present invention is directed to the above drawbacks, and aims to provide an optical fiber residual length stability control device for a cable loose tube having a simple structure and a good residual length control effect.

Abstract

La présente invention se rapporte à un appareil de commande de stabilité d'une longueur de fibre en excès dans une gaine intermédiaire flottante de câble optique, ledit appareil étant disposé entre une machine d'extrusion de gaine intermédiaire flottante (5) et un dispositif de traction de gaine intermédiaire flottante (6). L'appareil présente les formes structurelles suivantes : une section d'extrusion (2) raccordée à la machine d'extrusion (5), une section de traction (4) raccordée au dispositif de traction (6), et une section de transition (3) raccordée à la section d'extrusion (2) et à la section de traction (4). Le déplacement d'une gaine intermédiaire flottante que génère la section d'extrusion (2) est plus important que le déplacement d'une gaine intermédiaire flottante que génère la section de traction (4). L'appareil de commande de stabilité d'une longueur de fibre en excès présente une structure simple et permet de bien contrôler de la longueur en excès.
