James How's it going old Friend!?!?!?
I think that what you are probably missing is the Fiber Namer in your ArcFM Config for the F_FIBER Table.
In Arc Catalog, right-click the F_FIBER Table and go to the ArcFM Properties -> Field Display Tab:
There you will want to set the Display Name Object in the Pull-down to Fiber Namer
See in screenshot here:
Let me know if that was it!?!?!
This is already set.
