Abstract
L'invention concerne les câbles pour la transmission numérique constitués d'un certain nombre de quartes torsadées, chaque quarte ayant un pas de tordage particulier, plusieurs quartes étant regroupées en une ou plusieurs couches dans un faisceau, et quatre faisceaux étant regroupés dans le câble. En vue de la réduction de la diaphonie surtout aux fréquences élevées utilisées pour la transmission numérique, on propose de n'admettre une identité de pas de tordage que sous certaines conditions. On obtient ainsi un câble d'une complexité réduite permettant un remplissage complet des circuits par des signaux numériques. Application : transmission MIC.
