Media Converter Switches do
more than just adapt from one
cable type to another. They’re
true Ethernet switches and
behave like switches within your
Ethernet network. This means you
can connect them together
indefinitely without worrying
about interrepeater links. Each
Media Converter Switch features
non-blocking switching archi-
tecture with a 2K MAC address
table. The 128K buffer memory
makes it easy to interconnect
10-and 100-Mbps devices.

Distance isn’t a problem.
Because they’re switches as
well as media converters, Media
