If only i could find a cheap 4 port 10ge switch frown.gif!

i wonder how they're magically getting 2.5Gbps out of 5e? I'm curious of some of the older cat5e houses capability to run those higher speeds and the quality of those cables..

Chart in the article explains things at a glance, and the PDF of the specification goes into more detail.

More bit's per Hz while using more of CAT5e's bandwidth capacity.

rolleyes.gif As others have pointed out, if you actually put a little thought into your comment you'd probably gather that 700+ drops over hundreds of thousands of square feet is probably not referring to the back-end network.

Try to be constructive instead of uselessly pedantic. We have 10Gbit fibre between core switching and from building to building. SAN fabric is FC.

Where was that posted? I didn't see it. Sounds like you just made it up.

Cat 6a and Cat 7 cables are cheap compared to 10 Gigabit switches. I don't mind shelling out money for Cat 7 cables if I can buy a silent, consumer 10 gigabit switch for under $500. rolleyes.gif

Ruibbish!! biggrin.gif

Just attach your CAT8 to the end of your CAT5E and pull it through! Easy!

Hell I only wish it was that easy.

As someone that electrical for a living, if it is not in conduit. Just Attaching a new cable to an old one and pulling does not always work.
