LAN Cable Construction
LAN cables have a number of characteristics in common with other types of
electrical cables. All electrical cables have continuity, which means that they serve
as a complete path for electrical current flow. Each end of a cable has some type of
connector for connecting the cable to the appropriate electrical device. Cables with
multiple wires usually have a pin assignment that describes how the wires are
arranged in the connectors.
