We use multicore fibre cables in our datacentre and nodes.
In Europe we can obtain these to order on specific
size. If we need to bring these back to a central area we 
use an ODF and and then patch accordingly with fibre boxes
in cabinets. The multicores are in a rugged PVC type plastic
sheath [same type of plastic/pvc that is used for gas piping
in the streets here in Europe]. You have to do some serious 
hacking to damage this type of cable, and if you've ever
been to Telehouse in London you'll know how the type
of situation that I mean.

This is the company we use in the UK to do a lot
of this work

I can't recommend them highly enough.

You may also want to look at passive optical stuff that you
can use to cheaply use to do cdwm.

Neil.
