If you need to connect together multiple switches and the switches are
physically separated by more than 2 kilometers (1.24 miles), or if you
want to build a 1000 Mbps backbone network between switches, you
can use AT-8024GB Fast Ethernet Switches and install fiber optic GBIC
modules. The modules span large distances and, with an operating
speed of 1000 Mbps, can provide a fast backbone between the switches.
Figure 17 illustrates another collapsed backbone topology, this time
using a high speed, fiber optic 1000Base Ethernet switch as the focal
point. Six AT-8024GB Ethernet Switches, each with a GBIC module, are
interconnected via a Gigabit Ethernet switch.
