No, I mean period. Cable plant lifespan in the corporate world is 10 years. For residential, it's virtually the life of the house. Talking with people on the 10GigE working group, none of them would even consider a copper interconnect 4 years ago. Now we have one. Will it run on Cat6 or even Cat7 (mostly used in Germany, it's very well shielded) NO. You can't even come close to comparing Cat6 to the twin-ax that is needed for 10GBase-CX4 There is work being done on IEEE802.3an / 10GBASE-T, which will work over Cat 6A (not Cat6, it's the same as Cat5E vs Cat 5, it might test out, it might not). This standard might get ratified in 2006. http://h41111.www4.hp.com/procurve/uk/en/pdfs/technical_tools/10Gig_Cabling_technical_%20brief.pdf I personally don't recommend Cat 6 over Cat 5E for most new installations. GigE to the desktop will be sufficient for the next 5-10 years. Servers, on the other hand might need more, but they are more apt to have cable replaced. This is coming from a person who has already deployed GigE to the desktop. Harry > >Cat 5E does GigE, Cat 6 does GigE.
