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

550m. A 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km. 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 or 1000BASE-LH 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.
