If you need to connect together multiple switches and the switches are
physically separated by large distances, you can use AT-8024GB Fast
Ethernet Switches and install fiber optic GBIC modules. The modules can
span large distances and, since they operate a 1000 Mbps, can be used
to build a fast backbone between the switches.
One method for connecting multiple switches is with a collapsed
backbone topology, using a high speed 1000Base switch as the focal
point of the backbone. Figure 21 illustrates a topology that links
together six AT-8024GB Ethernet Switches using an AT-9006SX Gigabit
Ethernet switch. Each AT-8024GB Fast Ethernet Switch has a fiber optic
GBIC module.
