The next example illustrates a topology that is commonly referred to as a
back-to-back topology. Here, media converters are deployed at both the
central office and the remote sites. Each pair of converters transfers
network traffic from twisted pair cable to fiber optic cable and back again to
twisted pair cable. Furthermore, the media converters at the remote sites
that have powered devices provide Power over Ethernet.
