We put a pair of FiberCom Whisperlan transcievers into operation
recently.  These are running over about 2000' of fiber between
two buildings here at Rutgers.  One end is plugged directly into
an IP/DECNET Gateway (CISCO) and the other is plugged into a
TCP multiport box which intern has the central gateways (a collection
of several CISCO boxes and a VAX 750).  The boxes cost about $850
and we haven't had any problem with them.  They have the advantage
(unlike the Codenol, I believe) of allowing multiple units to be
ringed.  That is, you can connect three or more of these boxes
together using fiber rather than using them as a point to point
link.  This ends up saving you the price and the overhead of a
board in the CISCO box in the middle of the net having to copy
packets bridging accross the two fiber segments.

There are a number of others coming on the market including one
from Optical Data Systems that claims to be selling for under $600.
We haven't seen them yet.
