Network cable wiring sequence

　　The wiring sequence of the network cable generally follows the TIA/EIA 568B or TIA/EIA 568A standards. The following is the detailed wiring sequence of these two standards:

　　TIA/EIA 568B standard

　　The TIA/EIA 568B standard is one of the most commonly used network cable wiring sequences, with the color order from left to right (or top to bottom, depending on the viewing angle) being:

　　white orange

　　orange

　　white green

　　blue

　　white and blue

　　green

　　white brown

　　brown

　　TIA/EIA 568A Standard

　　The TIA/EIA 568A standard is used in some special occasions, such as connecting two computers to form a local area network. Its color order is from left to right (or top to bottom):

　　white green

　　green

　　white orange

　　blue

　　white and blue

　　orange

　　white brown

　　brown

　　Precautions for making network cables

　　Straight-through cable and cross-over cable: Straight-through cable means that the crystal heads at both ends of the network cable follow the same wiring standard (either 568A or 568B). Crossover cable means that the crystal head at one end of the network cable follows the 568A standard, and the crystal head at the other end follows the 568B standard. Straight-through cable is usually used to connect computers with switches, hubs and other devices, while cross-over cable is used to connect two computers or two devices of the same type.

　　Crystal head production: When making the crystal head of the mesh cable, you need to peel off the mesh cable for a certain length, then arrange the internal 8 wires neatly according to the above color sequence, insert them into the crystal head, and use the mesh pliers to clamp them. Make sure that each wire is inserted into the corresponding pin hole of the crystal head and is not loose or exposed.

　　Test and inspection: After the production is completed, the network cable needs to be tested with a network cable tester to ensure that its connectivity and tranSMission speed meet the requirements. If the test fails, you need to check whether the crystal head is made correctly and whether the network cable is damaged or in poor contact.

　　In conclusion, the wiring sequence of the network cable is crucial to the stability and transmission speed of the network. When making the network cable, be sure to follow the correct wiring standards and pay attention to the production method and testing procedures of the crystal head.
