Remote Connection 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.

A1000BASE-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.
