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 5 km, and a 1000BASE-ZX link up to 100 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

core connections between buildings in a campus setting. And for long-haul

connections, a 1000BASE-ZX SFP transceiver can be used to reach another site up

to 100 kilometers away.

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