metal braided data cable

The metal mesh is used to shield the surrounding electromagnetic interference, such as cell phone signals, wifi, etc., to protect the signal quality transmitted within the cable. The charging cable is not shielded, only the extension is no problem, the signal cable needs to be shielded, especially for earphones, audio and the like to transmit analog signals.
Weaving and aluminum foil for shielding effect and increased anti-interference ability. During data transmission, the external electromagnetic wave signal will interfere with the internal transmission signal of the wire, resulting in slower, weaker and more distorted data transmission. Among the red, white, green and black 4-core lines, red and black are power lines, and white and green are signal lines. If you just want to charge, you only need red and black lines, you can also charge the white and green. But if you want to transfer data, such as reading the memory information of the mobile phone with a computer, then you must have a white and green core wire for data transmission.
