Remote Connections with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type.
A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away,
and a 1000BASE-LX (SMF) link can run up to 5 km. This allows the
Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.
A 1000BASE-SX SFP can be used for a high-speed connection between
floors in the same building, and a 1000BASE-LX SFP can be used to
connect to other buildings in a campus setting.
The figure below illustrates this switch connecting multiple segments with
fiber cable.
