Central Wiring Closet

APPLICATION EXAMPLES

Central Wiring Closet

With 24 parallel bridging ports (i.e., 24 distinct collision domains), this switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.

In the figure below, the 1000BASE-T RJ-45 ports on the switch are providing 1 Gbps full-duplex connections for up to 24 local segments. In addition, the switch is also connecting remote servers over fiber optic cable at 1 Gbps.
