Is the aluminum foil paper a shielded network cable?

　　The mesh cable with aluminum foil may be a shielded mesh cable, which needs to be judged according to other characteristics of the mesh cable.

　　Shielded network cable refers to the network cable with a shielding layer inside, and the shielding layer is mainly composed of aluminum foil and woven mesh. Among them, the shielding layer of a single shielded network cable is only a layer of aluminum foil paper, which wraps the outside of the twisted pair of the network cable to reduce the impact of electromagnetic interference (EMI) and radio frequency interference (RFI). Therefore, if the network cable has a layer of aluminum foil, it is likely to be a single shielded network cable.

　　However, the double shielded cable has two layers of shielding: the first layer is an aluminum foil layer outside the twisted pair, and the second layer is a metal woven mesh. This double shielded cable provides a stronger electromagnetic shielding effect and is suitable for network environments that require high-quality tranSMission and anti-interference capabilities, especially in environments with strong interference, such as near high-voltage wires or audio equipment.

　　Therefore, although the aluminum foil cable may be a shielded cable, it is also necessary to check whether there are other shielding layers (such as metal woven mesh) to determine whether it is a single-shielded or double-shielded cable. At the same time, the choice of shielded cable also needs to be determined according to the specific application environment and needs.
