You can actually do 10Gb ethernet over copper, needs to be cat 6A cables
though, and it's only good for 100m. By the time you start faffing
about with stuff like that I figure the answer is fiber.

Fiber vs copper... If you are thinking of going beyond 1Gb then fiber
is the only game in town from what
I can tell. If you only want to 'back haul' from the switches to the
central router at your NOC at say 10G
at some time, then fiber it needs to be.
I helped build a data center at one time, and in each row we had
switches with a fiber up-link port
that went directly back to the core routers. The router and switches
were rated at 1G speeds.
We also had copper on the switches on each row to serve the machines
in that row of cabinets
that did either 100Mb or 1Gb depending on what the client computer
used or could handle. It
worked well. Another thing we did was to run at least two sets of
fiber when one would do for the
'insurance'. When running copper or fiber the manpower seems to be
more expensive than the media.
In your case, if you are re-running fiber, I might run 2 sets of fiber
and 2 runs of copper at the same
time. All together it could future proof your setup. Just document
for yourself and others as to why
you are NOT using all the media that was run.
