You could use fiber and a fiber conversion box.

Or you could use a switch or repeater half way.

Hi NANOG,

Could someone please help me with a fast ethernet problem I am having.  We
have a POP in a 27 floor building, and have a rj45 run from the the bottom
of the building (in the telco room) to the top of the building.  We have
cisco switches on either end and we are seeing about 5-20% packet loss on
the trunk.

Are we running into a distance limitation of fast ethernet, or are we suffering
from another problem?  I read that 328 feet is the limitation of fast
ethernet. Is there anything short of getting a repeater for the cable run
that I can do to boost the signal?

TIA for your help.

Ciao.
