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.

T3 / DS3 is usually handed off over twin coax ( copper ). out under the
street, these days, hard to tell what the medium or the transport really is
