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
1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This
allows a switch 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 10GBASE-LR module can be used for
high-bandwidth core connections between buildings in a campus setting. For
long-haul connections, a 1000BASE-LH SFP transceiver can be used to reach
another site up to 70 kilometers away.
The figure below illustrates three Gigabit Ethernet switch stacks interconnecting
multiple segments with fiber cable.
