Ethernet twisted pair cable
An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly transmits
analog signals and is advantageous in transmitting data over shorter distances. The maximum
transmission distance is 100 m (328.08 ft).
RJ-45 connector
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two
ends.
Figure 73 shows the pinouts of an RJ-45 connector.
