[Q] How can I visually distinguish a patch cable from a crossover cable?
[A] Assuming that your cable has been produced using correct and certified materials, this is pretty easy:
Patch Cable - If you are holding the cable with the copper contacts facing upward and the RJ45 plug pointed away from you, it should be easy to see the individual pairs through the clear plug. The first wire from left to right should be the white/orange wire. This will be followed by orange, white/green, blue, white/blue, green, white/brown, brown. NOTE: both ends of the cable will have this wiring configuration.
Crossover Cable - Using the same visual orientation, verify that one end of the cable has the wiring configuration listed above. If you have a crossover cable, one end will start with the white/green wire. This will be followed be green, white/orange, blue, white/blue, orange, white/brown, brown. NOTE: Once again, on the crossover cable the ends will be different.
If you have a cable tester, it can also verify your cable as being either a patch or crossover. A patch cable plugged into a test will read 12345678. A crossover cable will read 36145278 .
These are the quickest and easiest ways to properly identify your cable.
