Title (EN) COMMUNICATIONS CABLE WITH IMPROVED ELECTRO-MAGNETIC PERFORMANCE
(FR) CÂBLE DE COMMUNICATION PRÉSENTANT DE MEILLEURES PERFORMANCES ÉLECTROMAGNÉTIQUES
Abstract:
(EN) A communications cable (22) having a plurality of twisted pairs (26) of conductors and various embodiments of a metal foil tape (34) between the twisted pairs (26) and a cable jacket (33) is disclosed. The metal foil tapes (34) include a cut (37) that creates discontinuous regions (38) in a metal layer (35) of the metal foil tapes (34). When the metal foil tapes (34) are wrapped around the cable core (23), the discontinuous regions (38) overlap to form at least one overlapping region. The cuts (37) are formed such that overlapping region is small and limits current flow through the metal foil tapes (34), thereby minimizing alien crosstalk in the communications cable (22).
(FR) La présente invention concerne un câble de communication (22) ayant une pluralité de paires torsadées (26) de conducteurs et divers modes de réalisation d'une bande de feuille métallique (34) entre les paires torsadées (26) et une gaine de câble (33). Les bandes de feuille métallique (34) comprennent une découpe (37) qui crée des régions discontinues (38) dans une couche métallique (35) des bandes de feuille métallique (34). Lorsque les bandes de feuille métallique (34) sont enroulées autour de l'âme de câble (23), les régions discontinues (38) se chevauchent pour former au moins une région de chevauchement. Les découpes (37) sont formées de telle sorte que la région de chevauchement soit petite et limite une circulation de courant à travers les bandes de feuille métallique (34), ce qui permet de réduire à un minimum la diaphonie exogène dans le câble de communication (22).
