Fibre Optic Cabling - Where to start?
Solution 1:
For the lengths you're talking about just use LC-LC OM3, it'll support up to 10GbE and 8Gb FC as well as slower speeds, is relatively cheap and useable by just about every modern SFP/+ etc.
Oh and try minitran.co.uk, I find them excellent.
edit - have a look at the bottom three items in THIS list ok.
