Does it hurt to always crimp Cat-5e crossover cables to be compatible with Gigabit UTP Ethernet?
Question : Does it hurt to always crimp Cat-5e crossover cables to be compatible with Gigabit UTP Ethernet?
I’m new to the world of crimping cables, and have studied hard and learned familiarity with the specialised skill of properly wiring Cat-5/Cat-5e cables for straight-through and crossover applications. It’s all rather simple, actually, as long as one has the right tools such as a decent tester and crimper as well non-shoddy modular connectors and cabling. Cat-6[a/e] isn’t much more complicated, although a bit fiddly, what with the centre divider and tighter tolerances.
However, it appears that Gigabit UTP Ethernet crossover cables require the other pairs to be crossed over as well, meaning simple T568A/T568B wiring will no longer suffice. It’s all quite simple, but my question is whether there is any reason not to wire up *all* Cat-5e/Cat-6[a/e] crossover cables to be compatible with Gigabit UTP crossover requirements. After all, most modern good-quality Cat-5e cabling is quite up to handling Gigabit speeds, and is commonly used for that.

Who uses crossover cables anymore?
The only time I need a crossover cable is when working on really old kit.
Most active network devices support auto MDI, so crossover cables are rarely required.
If all you want to do is make a few cables for personal use it probably doesn’t matter what you do. If you want to move up to in-wall cabling with patch panels it does. Many places will use the same wiring infrastructure for devices other than PC connections (like phone systems). Varying from the standards in these environments cause all types of headaches.
