The following is a crossover cable diagram. Ethernet crossover cables are not used that often, but they are useful for connecting computers directly together in a small home network or in a circumstance when you need to quickly get data from one PC to another. It’s important to have one around, as sooner or later you’ll need one for something. With that said, they can be expensive. PCTechBytes recommends making your own network cables, as they can be cheaper and you can make a cable directly to your length specifications.
The following Ethernet crossover cable diagram represents the wiring for a Cat5 crossover cable:
The crossover cable diagram shows the transfer and receive wires are “crossed.” This allows the computers to talk directly to each others. In normal setups you’ll use a straight-through cable, where the wires are the same on each side. Computers are able to talk to each other with straight through cables because the routers, switches and hubs do the crossover internally.

Be sure to mark your crossover cable with tape or a permanent marker, as it will inevitably get mixed in with your straight-through cables and make your life miserable. We recommend making three crossover cables. One can be a few feet long, the second can be around ten feet long, and a third can be as long as you want. These cables aren’t used for long runs, so several short crossover cables will be more beneficial than a single long cable.
