Network cable crystal head ranking order

　　The ranking of the crystal head of the network cable follows the international standards TIA/EIA 568A and TIA/EIA 568B, which specify the order of the 8 cores in the network cable.

　　TIA/EIA 568A Standard

　　The order from left to right is:

　　white green

　　green

　　white orange

　　blue

　　white and blue

　　orange

　　white brown

　　brown

　　TIA/EIA 568B standard

　　The order from left to right is:

　　white orange

　　orange

　　white green

　　blue

　　white and blue

　　green

　　white brown

　　brown

　　In practical applications, the production methods of network cables are divided into two types: through wires and cross wires:

　　Straight-through cable: The crystal heads at both ends adopt TIA/EIA 568A standard or TIA/EIA 568B standard. This cable is usually used to connect different types of devices, such as computers connected to routers or switches.

　　Crossover cable: TIA/EIA 568A standard at one end and TIA/EIA 568B standard at the other end. This cable is usually used to connect the same type of device, such as a computer to a computer.

　　When making a network cable, the following points need to be taken into account:

　　Use professional cable pliers to peel off the outer skin of the cable to expose the 8 cores.

　　Arrange the cores in the order of the selected standard and cut the threads.

　　Insert the wires into the RJ45 crystal head, making sure each wire is inserted to the bottom.

　　Use wire tongs to press the crystal head tightly, ensuring that the wire core is in close contact with the crystal head.

　　Test whether the network cable connection is SMooth, you can use the network cable tester to detect.

　　In short, following the two international standards of TIA/EIA 568A and TIA/EIA 568B to make the network cable crystal head can ensure the stability and reliability of the network connection.
