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 stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
1000BASE-LX or 1000BASE-ZX SFP transceivers can be used to interconnect remote network segments, or can be used to provide a link to other buildings in a campus setting. 1000BASE-SX SFP transceivers can be used for Gigabit fiber connections between floors in the same building.
The figure below illustrates three TigerStack 10G switch stacks interconnecting multiple segments with fiber cable.
