Remote Connections 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, a
1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-ZX link up to 70 km. This
allows a Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct
connectivity for a widespread LAN.

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