Cat6 cable is more reliable at higher speeds than Cat5e. Cat6 is backward compatible with Cat5e, so you can mix and match, but they are different on the inside, where it counts so if you mix them you’ll never reach the full performance level you would if you used only cat6 cable, cat6 jacks, and cat6 mod plugs and cat 6 patch panels. Until recently, most home routers supported speeds of 10 or 100 megabits per second. However, Gigabit Ethernet routers have become more common. Cat5e and cat6 cables can both work with Gigabit Ethernet. Cat 5e cable is enhanced to reduce interference so that it can reliably deliver gigabit speeds. However, Gigabit Ethernet still pushes the cable to its limits.
Cat 6 cable is certified to handle Gigabit speeds, it's meant to handle it and it does. It's also suitable for 10-Gigabit although at that point, you're pushing the limits of Cat 6. Cat 6 cable also has more stringent specifications for cross-talk and system noise than Cat 5e does. That means you'll get fewer errors on a system operating via Cat 6. >> Browse Cat6 Cable @ cablesupply.com
