According to the functional direction and shielding structure of the shielded network cable, it is divided into a single-layer shielded network cable and a double-layer shielded network cable. The single-shielded wire shielding structure is a layer of aluminum foil shield; the double-shielded wire shielding structure is aluminum foil shielding + metal braided mesh. In terms of shielding function, Greatjammer double shielded network cable is more powerful.
In a strong electromagnetic interference environment, the signal transmission is stable, preventing external signals from interfering with the cable transmission data, preventing information leakage and eavesdropping. The signal jammer structure of the shielded network cable has the inherent advantages of resisting the internal crosstalk of the cable, can reduce the radiation interference of external high-power equipment, prevent the electromagnetic radiation of the wire itself from leaking, and prevent the signals released during the binding and wiring from affecting each other. Although shielded cables have strong performance, strong shielding, and double the transmission rate, the wiring requirements are extremely high. The wiring requirements of the shielded network system, in addition to shielded high-quality network cables, the components of the shielded network system, such as crystal plugs, routers, switches, etc., must be shielded. If the components are not shielded, the entire network shielding system will be invalid. , Other components and cables with shielding system will become the largest source of signal interference in the entire LAN. The complete system equipment with shielding function and cable grounding is the basic requirement for shielded network cable wiring. Cable grounding is very important for the network wiring of shielded network cables. Shielded network cable grounding First, the wiring structure needs to have good low-line wiring conditions. We can observe that there is a single copper wire in the internal structure of the shielded cable. This is the ground wire in the cable. The grounding wire is well grounded, and the shielding wire can better shield interference signals and ensure the high-speed operation of the network system. Improper grounding can cause noise. In the early transmission channel, the travel shielding failure will produce a potential difference, which will generate a strong current in the metal shielding layer of the metal cable itself, and the cable itself will become the largest source of interference. Considering that the cables need to be connected through outdoor cables, there are safety risks, such as thunderstorms or equipment failures, which may cause the voltage at one end of the cable to increase, and grounding at both ends can balance the voltage and lead current into the ground.
