The impetus to implement FDDI on twisted pair is to try to use what
already exists.  For that reason, the ANSI FDDI committee might well be
considering even unshielded twisted pair.  In any case, 150 meters is
likely to be the distance limit.

I would want to run fiber between the pieces of equipment as it might be
needed, without going to the hassle and expense of multiplexing into a
building-wide fiber backbone that somebody had built into the building.
I would prefer an office complex with the capability for adding or
deleting the fiber links as they were needed.  The price of fiber is
plunging, so I would acquire it with the equipment that it is to connect.
I wouldn't install any coax at all.
