Abstract
Uniformly spaced insulating buttons support two signal conductors within a tubular cable. The signal conductors are twisted from 180 to 360 degrees and are in physical contact with each other at their crossing point between each pair of buttons. Between each pair of buttons one of the conductors is covered with an insulating sleeve. The insulating sleeve alternates from one conductor to the other over the length of the cable. The conductors and buttons are enclosed within an insulating and supporting tubing. The supporting tubing is reduced in diameter or has corrugations to provide flexibility between each pair of insulating buttons. An overall shield composed of wires or foil is woven or helically wrapped to form a straight tube that surrounds the supporting tubing. The overall shield is electrically connected to system ground at the source end, allowing current flow only in the signal conductors. The signal conductors are electrically connected at both the source and destination ends, providing a foreward and return current path for the signal.
