Does the shielding effect still exist if the shielded cable is not grounded?<\/p>\n

No effect. If the shielding layer is not grounded, it cannot be shielded, which will not only interfere with the signal, but also the electrostatic voltage of the shielding layer is very high, which may cause component breakdown. The function of the shielding is to isolate the noise source from the electromagnetic field of the vulnerable equipment and avoid the propagation path of the electromagnetic noise source.<\/p>\n

Where are shielded cables generally used?<\/p>\n

1. Its function is determined by its own structure. Shielding is to reduce the impact of external electromagnetic interference on data transmission. It is generally used in computer room environments with complex electromagnetic environments and strong interference. Interference environment will cause the network cable transmission signal to be intermittent or even interrupted, and cannot be transmitted normally.<\/p>\n

2. It can resist interference, maintain normal transmission, and has excellent safety performance. Its shielding structure has structural advantages in reducing mutual interference between cables. It can protect external electromagnetic signals, and the aluminum foil structure can prevent the leakage of the cable's own magnetic signals. It will not affect the work of other cables due to the emission of interference signals, and can prevent information from being eavesdropped.<\/p>\n

3. For shielded network cables, you can use a shielded RJ45 plug to ground, and use a grounding wire to ground one end. The grounding wire can better protect the internal signal. Shielded network cables need to use wire connectors with metal shielding layers. The shielding layer on the wire must be tightly connected to the shielding layer. For connectors using ordinary wire clips, it is difficult to press manually.<\/p>\n

4. Do not use shielded cables when not necessary, because the wiring requirements of shielded network cables are very high. They must not only protect the system accessories, but also ensure a good ground connection. If the grounding is not good, the effect will be very poor.<\/p>\n
