How to Make Ethernet Cable
1.1
Method of Making Straight-through Cable
The pins in the two terminals of twisted-pair cable have to be in one-to-one
correspondence. If the first pin of one terminal is green, the first pin of the other terminal
must also be green. The twisted-pair cable made in this way is usually called
“straight-through cable”.

6 crossover connection: Twisted-pair cable has 4 pairs of pins (8 pins). Only
4 pins are used in network, namely the first, second and third, sixth pins. They are used for
receiving and sending signals. The connection rule is: the first pin of one terminal is
connected to the third pin of the other terminal, and the second to the sixth. Other pins are
connected to the corresponding pins. Cable made in this way is called “crossover cable”.
