Simon To answer your primary question, almost any fiber will work. It is difficult to order just a single strand of fiber. Maybe look at 6-12 strands and allow multiple networks to reduce overall load. If you have 6 x 1gb links you are free to manage the flow as you see fit and gain options for redundancy.
Its like buying a single can of soda at the super market, its just easier to buy the 12 pack.
