Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type.
A 1000BASE-LX SFP transceiver link can connect to a site up to 5 km
away. This allows the EdgeIron 4802CF to serve as a collapsed backbone,
providing direct connectivity for a widespread LAN. A Gigabit SFP
transceiver can also be used for a high-speed connection between floors in
the same building, or to connect to other buildings in a campus setting.
The figure below illustrates an EdgeIron 4802CF connecting multiple
segments with fiber cable.
