Cable Port type Application Reference
Console cable
Console port at one
end and 9-pin serial
port at the other end Connects the console port
of a router to a configuration
terminal.

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).
To extend the maximum transmission distance, you can use a repeater to connect two Ethernet
twisted pair cables. You can use up to four repeaters to extend the maximum transmission distance
to 500 m (1640.42 ft).
RJ-45 connector
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two
ends.
Figure 1 shows the pinouts of an RJ-45 connector.

Cable pinouts
EIA/TIA cabling specifications define two standards: 568A and 568B for cable pinouts.
