How much bandwidth does cat 5e support?

I've read that cat5e can be 100mhz or 400mhz but I can't find out how this relates to bandwidth, I've used google and can't find anything lol.

125Mb per wire to bring to a total of 1Gbps.

Edit:Thinking about that, what happens with upload of Cat5 cable?

1gbit I believe, if that is what you're after

it might be a competitor

CAT 5 v. CAT 5e

[Q] What's the difference between CAT 5 cable and CAT 5e cable?

[A] CAT 5 cable and CAT 5e cable have several differences, the most important are as follows:

* Network support - CAT 5 cable will support 10/100 Ethernet. That is, Ethernet and Fast Ethernet. CAT 5e cable will support Ethernet, Fast Ethernet, and Gigabit Ethernet. CAT 5e Cable is completely backwards compatible, and can be used in any application in which you would normally use CAT 5 cable.

* Less crosstalk - Crosstalk is the electrical interference that results when one wire's signal effects another wire's signal. CAT 5e cable has been improved over CAT 5 cable in this respect, and crosstalk has been greatly reduced.

* Bandwidth - This is directly related to network support, in the sense that the bandwidth is the information-carrying capacity of a system. The greater the bandwidth, the greater the information-carrying capacity in a given period of time. CAT 5e cable is rated at 350 megahertz, and it is this increased bandwidth (compared to CAT 5 cable) that allows it to support Gigabit Ethernet.

I'm suprised that it's only 1Gb, my switch says 1Gb full duplex, I thought that meant it can support 2Gb/s?

Cat5e is 1gb full duplex.

How much bandwidth does cat 6 support?

I've heard that dual cat 5 cables are used to extend hdmi, how can they do this if they only have 2gb/s bandwidth?

The true bandwidth available (in hz) is probably not even utilised with 10gbit and I'm sure that in the future there will be new ways to squeeze more data down a cat5e. Just as we can now get 50mbit down a telephone line that was only designed for 20khz.
