Gigabit Interface Converter (GBIC) Expansion Slots
The AT-8024GB Fast Ethernet Switch has two expansion slots on the
front panel, labelled Port A and Port B, which correspond to Ports 25 and
26, respectfully. Each slot can accommodate one optional fiber optic
Gigabit Interface Converter (GBIC) Ethernet module.
An GBIC module is a fast and easy way for you to add an 1000 Mbps fiber
optic port to your Fast Ethernet switch. GBIC modules can be used to
extend the distance of your network, build a high-speed backbone
network between switches, or connect additional end-nodes to the
network, such as high-speed servers.
Figure 12 shows an example of a fiber optic GBIC module.
