4000 feet should be fine so long as the right cable is used and splicing
is done with adequate care.  If you choose connectors carefully, you may
be able to avoid changing them later -- pick one for which there are patch
cords going both to your current Ethernet equipment, and to the FDDI
connector type.  ST may be a good choice, but check what type of
patch cords are available.

The relevant standard is the ANSI PMD standard, X3.166.

Typical fiber : 62.5/125 graded index, multimode
Fiber length - multimode: 2km
Link loss budget - multimode: 11db
Connector type: Media Interface Connector (MIC)
	You might want the check with the manufacuture of the fddi equipment 
	you will use, some of them will use ST type connectors.
