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.
