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 the 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, a 1000BASE-LX SFP can be used to
connect to other buildings in a campus setting, and a 1000BASE-ZX SFP
transceiver can be used for a long-haul connection to a remote site.
The figure below illustrates this switch connecting multiple segments with
fiber cable.
