LANNING
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
1000BSE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to
100 km. This allows a Gigabit Ethernet 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 SFP transceiver
can be used for core connections between buildings in a campus setting. And
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 TigerStacks interconnecting multiple
segments with fiber cable.
