Ethernet Cable The Ethernet cable uses an RJ-45 connector and category 5 twisted pair cable.

Figure 30 Ethernet Cable Assembly

The Ethernet cables are classified as straight-through network cable and crossover

network cable. They have the following features:

■ Straight-through network cable — The sequences of the wires crimped at the

RJ-45 connectors at each end are the same (see

Table 18). The cable is used to

connection between a terminal device, such as a PC or a router, and the Hub or

LAN Switch. Straight-through network cables are delivered with the router.

■ Crossover network cable — The sequences of the wires crimped at the RJ-45

connectors of the two ends are different (see

Table 19). The cable is used in the

connection between the terminal device, such as a PC or a router, and the

terminal device. You can create this cable yourself, if necessary.
