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.
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 EZ Switch 10/100/1000 switch stacks
interconnecting multiple segments with fiber cable.
