Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. Using a 
1000BASE-SX multimode fiber (MMF) SFP transceiver, you can run a link up to 550 m, 
a 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km, and a 1000BASE-LH 
single-mode fiber (SMF) link can run up to 70 km. This allows the switch to serve as a 
collapsed backbone, providing direct connectivity for a widespread LAN.

1000BASE-LX, 1000BASE-LH, or 100BASE-FX SFP transceivers can be used to 
interconnect remote network segments, or can be used to provide a link to other 
buildings in a campus setting. 1000BASE-SX SFP transceivers can be used for 
Gigabit fiber connections between floors in the same building. 

The figure below illustrates this switch connecting multiple segments with fiber cable.
