What's your measured chromatic dispersion?  You might need 
to budget in the hit from compensation too.  Some of the
super long range optics have wide tolerance of dispersion,
but probably not without a penalty.  

If you don't have a measurement, you can estimate w/ the values 
for that fiber type.
