As illustrated in the next topology, the media converter can also be
deployed at a central office if the remote devices have fiber optic ports. In
the example, the media converters are connected to the AT-9424Ts
Gigabit Ethernet Switch at the central office with twisted pair cable and to
the remote devices, in this case AT-GS950/16 Gigabit Switches that have
SFP transceivers, over fiber optic cables. Since the AT-9424Ts Gigabit
Ethernet Switch is not a powered device, the PoE feature on the media
converters is not used.
