Remote Connections with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type. Using a
1000BASE-SX multimode fiber (MMF) SFP transceiver, you can run a link up to
550 m. A 1000BASE-LX single-mode fiber (SMF) link can run up to 5 km. A
1000BASE-LH single-mode fiber (SMF) link can run up to 70 km. This allows the
switch to serve as a collapsed backbone, providing direct connectivity for a
widespread LAN.
1000BASE-LX or 1000BASE-LH SFP transceivers can be used to interconnect
remote network segments, or can be used to provide a link to other buildings in a
campus setting. 1000BASE-SX SFP transceivers can be used for Gigabit fiber
connections between floors in the same building.
The figure below illustrates this switch connecting multiple segments with fiber
cable.
