II. Making an Ethernet cable
To make an Ethernet cable with RJ45 connectors using a category-5 twisted-pair cable,
refer to Figure 8-8. A category-5 twisted-pair cable is composed of eight wires that are
identified and grouped by colors of the outer insulator. Usually a solid color wire and a
white/solid color wire are organized in pairs. But sometimes, wires are also paired by
color coded points.
