2-5Remote Connections with Fiber CableFiber optic technology allows for longer c abling 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, and 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, 1000BASE-LH, or 100BASE-FX SFP transceivers can be
used to interconnect remote network segments, or can be used to p rovide
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.
