RJ-45 Plug and RJ-45 Connectors

In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use

RJ-45 plugs. The RJ-45 plug accepts 4-pair UTP or shielded twisted-pair (STP) 100-ohm

cable and connects into the RJ-45 connector. The RJ-45 connector is used to connect

stations, hubs, and switches through UTP cable; it supports 10 Mbps, 100 Mbps, or 1000

Mbps data transmission.

Figure D-4 shows the RJ-45 plug and RJ-45 connector.
