Copper is available. It just depends on what your network guys are comfortable 
with in their environment.
If you are capable of filling the pipe you can get about 8.2Gbps. Filling the 
pipe requires higher levels of multiplexing and lots of source points or 
multiple jobs.

I think feeding the pipe is the hardest problem and 10GBps performance is 
typically rated at 200-250 MiB/s in practice, at least from what I have seen.
