Remote Connection with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type.
A 100 Mbps multimode fiber (MMF) link can run up to 2 km, and a 100
Mbps single-mode fiber (SMF) link can run as far as 20 km. This allows
the switch to serve as a collapsed backbone, providing direct connectivity
for a widespread LAN.
The 100BASE-FX (SMF) plug-in module or 1000BASE-ZX GBIC
transceiver can be used to interconnect remote network segments. While a
1000BASE-SX GBIC transceiver can be used for a high-speed connection
between floors in the same building, and a 1000BASE-LX GBIC
transceiver can be used to connect to other buildings in a campus setting.
The figure below illustrates this switch connecting to a remote segment
with fiber cable.
