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,

a1000BASE-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.

A1000BASE-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.
