1. Different structures<\/p>\n

1. Shielded wire:<\/p>\n

A transmission line that uses a metal mesh braided layer to wrap the signal line. The braided layer is generally red copper or tinned copper. The shielding layer of the shielded cable is mainly made of non-magnetic materials such as copper and aluminum, and the thickness is very thin, much smaller than the skin depth of the metal material at the frequency of use. The effect of the shielding layer is mainly due to the grounding of the shielding layer. Different grounding forms will directly affect the shielding effect.<\/p>\n

2. Unshielded cable:<\/p>\n

Eight different colored wires are twisted together in four pairs. The purpose of twisting in pairs is to minimize the impact of electromagnetic radiation and external electromagnetic interference. Unshielded twisted pair cables have no metal shielding material, only a layer of insulating rubber wrapping.<\/p>\n

2. Different connection methods<\/p>\n

1. Shielded wire: A wire with a conductor wrapped around the outside of the conductor is called a shielded wire. The wrapped conductor is called a shielding layer, which is generally a woven copper mesh or copper foil (aluminum). The shielding layer needs to be grounded, and external interference signals can be conducted into the ground by this layer.<\/p>\n

2. Unshielded cable: It is wrapped with only one layer of insulating rubber and directly physically connected. There is no need to consider grounding issues. It is flexible in networking and easier to install.<\/p>\n

3. Differences in data transmission quality<\/p>\n

1. Shielded wire: Due to the existence of the shielding layer, when it is grounded, it can ensure that the transmitted data is not leaked, and it will not be affected by external electromagnetic interference, so the accuracy of the data can be guaranteed.<\/p>\n

2. Unshielded cables: They are easily interfered by strong electromagnetic radiation from the outside world, and the quality of data transmission is not as good as that of shielded cables.<\/p>","protected":false},"excerpt":{"rendered":"
