Hello,


I am watching to buy cables (rj45) for my colocation, but I see that there are several, are category 5, category 5E, and category 6, that differentiates has?



Thanks!

Cat5e is the standard. Cat5e will do 10/100/1000 ethernet amongst other things. Go with cat6 if you have a hefty budget, or have a potential need to ever push 10-gbit+ over copper (unlikely).

Most cat5 should be cat5e, since theres virtually no price difference. Cat6 *should* be around the same price (as it's the same damn wire, just a different twist rate afaik), but is far more expensive. Needless to say, anything you get that really is cat5 (not cat5e) would probably be old and dusty, and I wouldn't use it in a production environment.

then:


cat5, old, is not worth.

cat5-E (Enhaced Cat5-E), good, for networks not gigabits

cat6 , gigabit and work of the Cat5


I am going to work with networks fiber of 100mbps, networks of 100mbps, as he is the best one for my? 5E? or I am mistaken?



Thanks!

Cat5e is all you should be buying essentially.

Cat5e will do gigabit, but not 10Gbit (if I'm not mistaken, you might be able to run 10Gbit on cat5e, but I've never even seen it run on copper, so I wouldn't know).

Cat6 is relatively useless, the only practical application I can see for it is when you need 10Gbit connectivity between devices, and fiber ports on the actual devices are too expensive (eg. copper gbit right now is substantially cheaper on many devices then fiber, and has higher port density).

Ideally speaking, you should never be running cat6 in a data center environment, because anything pushing even 1gbit+ should be on fiber (ideally speaking that is).

Thanks porcupine!


Enhaced Cat 5 = Cat5E ? Right?




Thanks again

No, they're different, if it doesen't say "5e" or "category 5 enhanced", don't buy it.

[Doble]

sorry, not understand


CAT 5 Enhaced = CAT5-E ?



Thanks

[Doble]

yes or no?

[webink]

yes, cat5E is the successor to standard cat5. That is why it can push more data at faster rates, because it is enhanced.

[Doble]

you do not understand

I want to me to know if Cat 5 Enhaced means just like Cat5-E. Or 5 Cat Enhaced is the simple CAT5?

Cat5-E and Cat5 are not the same. Any Cat5 you buy today will be either absurdly old (5+ years sitting on a shelf), or Cat5-E generally speaking though.

[Doble]

"E" = Enhaced?
"E" it means Enhaced?

[porcupine]

thats correct.

[Doble]

Thank's Friend!!!

We sell CAT6 by the cart load. It's twice the price for the same performance on current equipment. It's less flexible, and more difficult to crimp (Due to the plastic divider that runs down the cable). I always try to talk people out of it, but they want it because it's newer, and they read about it in some magazine.

Oh well, I usually don't argue when people spend more money with us . For people doing new installations in walls of houses, I've seen about 50% choose CAT-5E and 50% go with CAT6. Mainly because CAT6 will probably carry them further in the future than CAT5E. If you are buying patch cables, go with CAT5E, and save some $$.
