Non-Crossover (Patch) Ethernet Cables
In a non-crossover cable, the wires running to each pin are connected
in the same order on both ends. In other words- no cables are
crossed.
About the Pins
Data Transmit: Pins 1 and 2
Data Receive: Pins 3 and 6
Unused: Pins 4, 5, 7, 8
You would use this
cable with...

Crossover Ethernet
Cables for Gigabit Signals
Like the crossover cable above, a Gigabit crossover cable has all of
its wires
crossed, and all wires are bi-directional. The connections on this
crossover cable are in a different order than the connections on a
10-Base T/ 100-Base T Crossover cable. Gigabit transmission can also be
called 1000-Base T and can also be used to transmit 10-Base T/100-Base
TX signals.
About the Pins
Every wire is capable of transmitting and
receiving- but they are paired:
Pair A: Pins 1 + 2
Pair B: Pins 3 + 4
Pair C: Pins 5 + 6
Pair D: Pins 7 + 8
You would use this
cable when...
Directly connecting 2 devices on a 10-Base T/
100-Base TX/ Gigabit network
