With 26 parallel bridging ports (i.e., 26 distinct collision domains), these
switches can collapse a complex network down into a single efficient
bridged node, increasing overall bandwidth and throughput.
In the figure below, the 10/100BASE-TX ports on the switch are providing
100 Mbps connectivity for up to 24 segments, while the 1000BASE-T ports
are providing connectivity for two Gigabit segments.

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, a 1000BASE-LH link up to 70 km, and
a 100BASE-FX (SMF) link up to 20 km. This allows the switches to serve as
a collapsed backbone, providing direct connectivity for a widespread LAN.
The figure below illustrates the ES-3026P connecting multiple segments
with fiber cable.
