Collapsed Backbone - Switch Topology - Allied Telesis AT-8016F/MT Installation Manual

Collapsed
If you need to connect together multiple switches and the switches are
physically separated by more than 2 kilometers, or if you want to build a
Backbone -
1000 Mbps backbone network between switches, you can use
Switch
AT-8024GB Fast Ethernet Switches and install fiber optic GBIC modules.
Topology
The modules span large distances and, with an operating speed of 1000
Mbps, can provide a fast backbone between the switches.
Figure 21 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 the Gigabit Ethernet switch.
