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 10 km, and a 1000BASE-ZX link up to
70 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. For long-haul connections, a
1000BASE-ZX SFP transceiver can be used to reach another site up to 70
kilometers away.
The figure below illustrates three switches interconnecting multiple
segments with fiber cable.
