MOTOROLA MVME148-001 Multiplexer switch card

The workstations and servers of the network are connected either directly to a switch or through an Ethernet hub. The switches themselves are connected through their fiber optic ports, which have a maximum operating distance of 2 kilometers (1.24 miles). The figure also illustrates how you can use the fiber optic ports to connect other remote devices to the network, such as remote servers and workstations.

Collapsed Backbone - Switch Topology

 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.
