	I second Walt's analysis.  STs align much better than SMAs.  We started
out with SMAs on Proteon's Pronet-80 and switched to STs for all but the f/o
interfaces.  You can make or buy a custom patch cord for end-node termination
to anything that is not ST.

	I'd like to find a good non-epoxy, non-polish ST or FSD connector.  That
would really save some money in the field.

	We have been playing around with AMP's FSD (Full Shroud Duplex) connectors.
We are finding them very tricky to build and so are considering staying
with STs 
for field connectorization in the FDDI environment.  We would buy the FSD patch
cords.	Anyone found a field connector for FSD that works well?
