As far as WAN goes, anything above DS3 is typically fiber (or wireless in 
some cases). Copper CAN support much higher speeds (at least in a LAN 
environment), including GigE (and, I wouldn't be surprised, 10GigE when it 
comes out). DS3 is coax (copper) or fiber.

Hello,

Does anyone know what is the fastest rate a copper wire can support?
 i.e.  Which one of these rates (T-3, OC-3 or higher) can I run over
copper wire?

Thanks in advance,

MD
