![]() The only reason this "advice" exists is because if you are only using 100Mb equipment, they will happily use this as a crossover cable. ![]() This means that the resulting cable is partially crossover, and partially straight. It should be clear why if you look at the colors- only green/orange are getting flipped, blue/brown are staying the same. You do not get a proper crossover cable by using T568a on one end and T568B on the other. I know that you see this all over the place, but it is WRONG. There's two ways to wire a connector : T568A (the one that starts with green, on the right) and T568B (the one that starts with orange) :įor a regular cable, you use same version on both ends (either T568A - T568A or T568B-T568B), for crossover cable one end must have T568A and the other end must have T568B (like in the picture above). Gigabit network cards have auto-detection of pair order, so you can use a plain network cable (like the one you use between computer and router) and make the connection between two gigabit network cards.Ĭrossover cable is only required if one of the cards is not capable of 1 gbps or if for some reason (buggy drivers, buggy chip) it can't automatically detect the pair order.
