   FDDI generally uses 62.5/125 fiber. 
All of ours used 50/125.  It has better performance, and it was the
standard when ours was installed.  A lot of other UK installations were
done later, and used 62.5/125 because that was more common in Europe at
that time -- but they're now regretting it as 50/125 has become the
standard for Gigabit.
