Abstract

L'invention porte sur un câble quadruplex différentiel à haut débit (1) qui comprend quatre lignes de signal (10) torsadées vers la droite ou vers la gauche et comprenant chacune un conducteur interne (11) formé par torsion d'une pluralité de fils conducteurs (11a) et une couche diélectrique (12) formée autour de la circonférence extérieure du conducteur interne ; et un conducteur externe (16) disposé à l'extérieur des lignes de signal et comprenant une pluralité de fils conducteurs (16a) qui sont torsadés dans le même sens que le sens de torsion des quatre lignes de signal. On en conclut que le comportement des quatre lignes de signal sera similaire à celui du conducteur externe lorsque le câble glisse étant donné que le sens de torsion des quatre lignes de signal et celui du conducteur externe sont les mêmes comme indiqué plus haut. En conséquence, une dégradation de l'impédance caractéristique et de l'atténuation du câble au début de l'étape de glissement du câble peut être supprimée.
