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.
