RJ-45 connector
Figure 4-16 Ethernet cable connector
Ethernet cables fall into straight-through Ethernet cables and crossover Ethernet
cables.
z Straight-through Ethernet cable: The wires of a twisted pair cable are crimped in
the same sequence in the RJ-45 connectors at both ends. A straight-through cable
is used to connect a terminal device (such as PC or router) to a hub or LAN Switch.
z Crossover Ethernet cable: The wires of a twisted pair cable are crimped in
different sequences in the RJ-45 connectors at both ends. A crossover Ethernet
cable is used to connect a terminal device (such as PC or router) to another
terminal device. You can make such a cable by yourself.
