This chapter describes cables used for connecting network ports.
Table 53 Cable description
Cable Port
type
Application
RJ-45 Ethernet port at one
end and DB-9 port at the
other end
Connects the console port of the gateway to
the console terminal.
RJ-45 Ethernet ports
Connects RJ-45 Ethernet ports to transmit
data.
XFP/SFP+/SFP/CFP/QSFP+
ports
Connects the fiber ports to transmit data.
Console cable
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for
connecting to the console port of the gateway, and a DB-9 female connector at the other end for
connecting to the serial port on the console 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).
RJ-45 connector
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two
ends.
shows the pinouts of an RJ-45 connector.
