With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), a
Gigabit switch stack can collapse a complex network down into a single efficient
bridged node, increasing overall bandwidth and throughput.
In the figure below, the 10/100/1000BASE-T ports in a stack of 48-port Gigabit
Ethernet switches are providing 1000 Mbps connectivity through stackable
switches. In addition, the switches are also connecting several servers at 10
Gbps.

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.
