RJ-45 Connector
The RJ-45 connector (shown in the illustration with an RJ-45 plug) is used to
connect workstations, hubs, and switches through unshielded twisted pair cable.
The RJ-45 connector accepts four-pair Category 3 or Category 5 UTP cable.
Only two pairs are used for 10BASE-T wiring.
BNC Connector
The BNC connector for the hub supports 10 Mbps data transmission and
connects the hub to other devices.
The BNC T-connector and the 50 Ω terminator enable the BNC port on the hub
to connect a thin coaxial segment.
