The manufacturer of Category 5 single-shielded network cable oxygen-free copper twisted pair tells you that the shielded network cable is mainly for the environment with strong interference. The environment with interference will cause the transmission signal of the network cable to be intermittent or even interrupted, and the signal cannot be transmitted normally. The use of shielded network cables can well resist interference, maintain normal transmission, and have good confidentiality performance. The shielding structure of shielded wiring has inherent advantages in reducing mutual interference between cables. It can not only shield external electromagnetic signals, but also aluminum foil. It blocks the electromagnetic leakage of the cable itself, does not emit interference signals to affect the work of other cables, and can prevent information from being eavesdropped.

The manufacturer of Category 5 single-shielded network cable oxygen-free copper twisted pair tells you that there will be a copper wire in the shielded network cable, that is, the ground wire. Shielded RJ45 sockets can be used, and one end of the drain wire is grounded when in use. The ground wire can better shield the external signal. Shielded network cables need good grounding, and shielded lines can well reduce the impact of strong interference on network signals. Do not use shielded network cables if it is not necessary, because the wiring requirements of shielded network cables are high, not only the accessories in the system are required to be Shielded, and must have a good grounding to play a role. If the grounding is not good, the effect will be very poor.
Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that if the grounding point is not arranged correctly, the grounding resistance is too large or the grounding potential is unbalanced, grounding noise will be caused, that is, a potential difference will be generated at two points of the transmission channel , so that interference currents are generated on the metal shielding layer. At this time, the shielding layer itself forms the largest source of interference. The wiring requirements of the shielded network cable are relatively strict. All accessories need to have shielding performance and a good ground wire system. Category 5 single-shielded network cable oxygen-free copper twisted pair The manufacturer tells you that in actual construction, it is difficult to perfectly ground all of them, so that the shielding layer itself becomes the biggest source of interference, resulting in performance that may even be inferior to unshielded twisted pair .
