Eli5: Why is it that there are multiple copper wires inside an electric cable and why are they coiled?
In: 68
In Cat5 cable, each copper wire has a specific function as it relates to data transfer. Power, send, and receive. Each copper wire is covered in a different color coating for making and tipping cables for installation. There is a recommended color scheme for, let’s say, a straight through cable. However, since they are all just copper you can technically use any scheme you want, as long as you use the same scheme on both sides of the cable.
