2-4Remote 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 switch stack 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 transceiver can

be used for high-bandwidth core connections between buildings in a

campus setting. 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 three GSW-2476 switches stack

interconnecting multiple segments with fiber cable.
