ABSTRACT:
A twin axial or parallel pair cable for high data rate differential signal transmission with extremely low skew. The cable has first and second plated electrical conductors which extend in substantially parallel relation to one another. Preferably the conductors are surrounded by first and second foamed fluoropolymer insulating dielectrics, respectively. The dielectrics and the conductors are surrounded by a braided metal shield of plated electrical conductors. The dielectrics insulate the conductors from each other and from the shield, and are sufficiently crush resistant to maintain the conductors in substantially parallel relation to one another over the length of the cable. The shield may be covered with an optional jacket.
