I'm confused, aren't these "fan
out" units just hubs?

These simply provide multiple ports on a single
tap. I indicated my
interest in them for the thick ethernet segment in my garage, as I only
have 3 transceivers tapped into it at the moment. Physically, they just
connect to the tapped transciever.
Which, as Chuck suggests, is a effectively a description of a hub, albeit that has AUI interfaces rather than 10-base-T.
Ethernet hubs are
technically
multiport repeaters, and are subject to all of the
topology and distance
limits of repeaters.
I'm not sure these are repeaters, though. So a signal that's sent from a
station on one of the AUI interfaces would go onto the wire, but I'm not
sure that it would get back (directly) to the other AUI interface(s).
Anyone know?
