Abstract

L'invention concerne un procédé de fabrication d'un câble optique avec fil d'emballage (6) se déroulant automatiquement sous la chaleur, qui se rapporte au domaine technique des communications optiques et comprend les étapes suivantes : (S1) sélection d'un matériau composite qui se déroule automatiquement à une température de 120 à 140 °C et préparation dudit matériau pour former un fil d'emballage (6) ; (S2) moulage par extrusion de tubes en vrac (5) à l'extérieur d'une pluralité de fibres optiques colorées au moyen d'une extrudeuse ; (S3) torsion d'une pluralité de tubes en vrac (5) autour d'un élément de renforcement central (4), enroulement d'un fil d'emballage (6) qui se déroule automatiquement sous la chaleur sur la périphérie de tous les tubes en vrac (5) pour former une âme de câble (1) ; (S4) revêtement d'une couche de blindage (2) sur une couche externe de l'âme de câble (1) ; et (S5) moulage par extrusion d'une couche de gaine externe (3) à l'extérieur de la couche de blindage (2), et le fil d'emballage (6) de l'âme de câble (1) se déroulant automatiquement sous la chaleur, formant ainsi un câble optique avec un fil d'emballage (6) se déroulant automatiquement sous la chaleur. Étant donné que le fil d'emballage (6) se déroule pendant le moulage par extrusion de la couche de gaine externe (3), un tube qui est légèrement aplati par le fil d'emballage (6) peut revenir automatiquement à sa forme d'origine, ce qui permet d'améliorer le défaut d'atténuation excessive de câbles optiques dans l'art antérieur de la technique provoqué par l'aplatissement des tubes en vrac par le fil d'emballage.
