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 10km
away. This allows the Gigabit Ethernet switch 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 a Gigabit Ethernet switch connecting
multiple segments with fiber cable.
