View Full Version : Network Cable Cat6?

25-03-2003, 09:40 PM
First of all what is the Specs of it?

I know what Cat5 and Cat5e Network Cables are but it's the first I've heard of Cat6. I was just looking through DSE's site and came across it. It doesn't explain what the difference is.

I'm assuming this Cat6 cable might be the one used on Gigabit networks, would that be correct?

I bought a couple of cat6 cables for my home LAN. The guy at DSE said that basically they are a better quality cable/better copper or whatever...and the 5e cables have a bandwidth of 200Mb/s..The cat6 has much higher.

The only possible advantage over Cat5 on a 10/100 network is that the cat6 will have less loss over LONG distance. Patch cabling and building wiring will make no difference. It's not like audio situations which involve high transient currents. Why pay extra?

Somewhere around/above 1000MBPS I was told!

Last I knew cat6 wasn't standardised yet. It might be now.

Cat5e can do 1Gbps over short distances.... Cat6 can do it over longer distances.

i was always told at Polytechnic, last year, that CAT stands for the shielding against interference like EMI
so cat 6 has better protection that cat 5

both cat 5 and 6 cables support 1000mbps (howerver if i was going to buy 1000mbps lan cards i would go with fiber)
it all depends on the NIC
this is a site that sells 1000MBPS cards and it says that
""The Micronet SP2610/SP2612 10/100/1000 Mbps Gigabit Ethernet Adapters provide high speed transmission over category 5 cabling.""

Sorry sc0ut but it is the characteristics of the cable to minimize capacitive and inductive effects which cause a degradation in the waveform.

Cat 6 is not yet a standard. Cat 5e is rated for Gigabit Ethernet.

There are some Cat 6 cables with a foil screen, which would have slightly better noise immunity than the UTP Cat 5/5e. You have to remember that all the twisted pair cables get most of their noise immunity from the balanced system. One thing you can be sure of: Cat 6 will cost more. :D

It's intended to have slightly better characteristics in one way, because there is a separator between the pairs. But the tolerance on time scatter between pairs is 38 ns, t\rather than 20 ns for Cat 5e, which is dangerously close to the 10/100 Ethernet limit of 40 ns.

Yeah, generally it costs more.. but it doesnt have to be much.. normally an extra $1 for a 3m one at DSE compared to a 3m Cat5e cable.

Last I saw both were on special and cost the same ;-)

There are better places than DSE to buy stuff as well.

I know there are better places to buy than DSE. I've got an account with them though and other places but none of the others did CAT6. Some had never even heard of it and just thought I meant Cat5e. I may buy the CAT6 cable though because I need 60M of it.
