Can the shielded network cable really eliminate interference? The

network cable is generally divided into an unshielded network cable and a shielded network cable. The shielded network cable and the unshielded network cable are distinguished by a metal mesh and aluminum foil paper. But the unshielded line does not. The shielded wire is matched with the shielded crystal head, which can effectively prevent the electromagnetic radiation interference of other high-power electrical appliances and strong power sources around, and greatly reduce the bit error rate of signal transmission. Cables can affect transmission speed due to two types of interference. One is external interference, and the other is crosstalk between lines within the same cable. External interference usually refers to electromagnetic interference, and the role of the shielded network cable is to resist interference and reduce radiation. Sometimes it will cause a misunderstanding, that is, the shielded cable is a shielded cable that can completely eliminate the interference and can not completely eliminate the interference. The shielded cable is only to ensure the stability of the network transmission and the strong magnetic field interference in the environment with strong interference. Most of the methods used in the shielding system are to cover the outer surface of the cable and the external parts with a metal material shielding layer to effectively filter out unnecessary electromagnetic waves.
