What is shielded network cable?

From the literal meaning, we know that one of the functions of the shielded Network Cable is shielding. The shielded network cable have a certain degree of resistance to the environment of strong interference? It can effectively shield the external electromagnetic interference, thus Ensure the stability of network transmission. The aluminum foil also isolates the electromagnetic leakage of the cable itself, avoids the mutual influence with other cables, and can prevent the leakage of information.
There is a copper wire in the shielded network cable, which is the ground wire, which can better shield other signals. The shielded network cable needs to be well grounded, and the shielded line can reduce the mutual interference of signals. The shielding structure of the shielded network cable has a fundamental advantage in reducing the mutual interference between cables.

The shielding method of the shielded network cable is different, and the shielded network cable is divided into two paths. One is STP (Shield Twisted-P) and the other one is FTP (F-Twisted-).

STP refers to a shielded network cable with an external shielding layer for each line, while FTP is a shielded network cable that uses a shielded network cable. It should be noted that the shielding is only used when the entire loop shielding device is not grounded. Therefore, the entire The system is completely shielded, including wiring, wiring, crystal head and rack, etc., and the system needs to have a good ground wire.
