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, a
1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-LH link up to 70 km.
This allows the switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.
A 1000BASE-SX SFP transceiver can be used for a high-speed connection
between floors in the same building, a 1000BASE-LX SFP transceiver can be
used to connect to other buildings in a campus setting, and a 1000BASE-LH SFP
transceiver can be used for a long-haul connection to a remote site.
The figure below illustrates the switch connecting multiple segments with fiber
cable.
