Abstract

A computer network that utilizes an Ethernet protocol. The computer network includes a first network device, a second network device, a first cable assembly coupling the first and second network devices to one another and facilitating data transmission from the first network device to the second network device, and a second cable assembly coupling the first and second network devices to one another and facilitating data transmission from the second network device to the first network device. Each of the first and second cable assemblies consists essentially of a cable, a first contact assembly and a second contact assembly. The cable is formed with a pair of wires that are twisted about one another and shielded by at least one shield conductor. Each of the first and second contact assemblies include a first conductor, which is electrically coupled to a first one of the wires, a second conductor, which is electrically coupled to the other one of the wires, and a third conductor, which is electrically coupled to the shield conductor.
