Back-to-Back Topology
In some network configurations you may want to interconnect two media
converters in what is referred to as a back-to-back topology. In this topology,
the media converters not only extends the distance of your network but also
converts the fiber optic cable from twisted pair to fiber optic and back again.
Figure 5 illustrates two AT-8124XL switches at different campuses
interconnected by two AT-MC106XL media converters. The 100Base-TX ports
on the media converters are connected to one 10/100Base-TX port on each
switch, while the 100Base-SX ports on the media converters are directly
connected together.
