Abstract
A high speed data communication link has a circuit for providing a differential signal having first and second opposite phase components and a triaxial cable connected to receive the positive phase component of the signal on the inner conductor and the negative phase signal component on the center conductor which is made of wire mesh. An outer conductor such as a foil tape or wire mesh has a drain wire connected to ground and provides electric field shielding. EMI cancellation is provided by this arrangement particularly where the inner and center conductors have approximately the same resistance.
