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 SFP transceiver
module links up to 70 km. This allows a 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 and a 1000BASE-LX SFP transceiver
can be used for high-bandwidth core connections between buildings in a
campus setting. For long-haul connections, a 1000BASE-LH SFP
transceiver can be used to reach another site up to 70 kilometers away.
The figure below illustrates three Gigabit Ethernet switches interconnecting
multiple segments with fiber cable.
