Cable categories are based on how the cable is manufacture. The critical points in network cables are the "number of turns" per feet and how consistent the twists are. The twisting of the conductors is very important as well as how the cable ends are terminated.

The link provided by Anna will help in getting the actual cable specs, just remember the higher the Cat number the better the specs.

I have had great success with Belden 1701.

Geeker,

They look the same, but are labelled differently. There is better quality control on Cat 5E, allowing less crosstalk. A professional installation requires carefaul adherence to ghuidelines, especially the less than 1/2" strip at the punchdowns etc.

Most importantly, Gigabit Ethernet 10/100/1000 has been found, in the field, to run more reliably on Cat 5E. The effect is cumulative, so a Cat %E installation requires certified 5E patch Panels, Bulk Cable, Patch Cord, Connectors, etc.etc.

Leviton has a nice complete line of end-to-end supplies.

Gigabit prices are plummeting, don't use Cat5!
