Cat7 shielded 10 Gigabit Ethernet cables are S-FTP twisted pairs, meaning each pair of wires has an aluminum foil shield, and within the sheath, there is another layer of copper wire mesh. The combination of copper and aluminum materials, along with the mesh and metal foil structures, forms a very strong resistance to electromagnetic interference, effectively suppressing both crosstalk between wire pairs and electromagnetic interference among them.

Are there any specific requirements for connectors with Cat7 shielded Ethernet cables? Currently, the most common interfaces in telecommunications networks are RJ-11 and RJ-45, with RJ-45 being the colloquial name for the standard 8-position modular connector. In the past, Cat5, Cat5e, and Cat6 cabling used RJ-type interfaces, mainly RJ-45. In Cat7 cabling systems, "non-RJ-type" interfaces are permitted. ARJ-45 adds four connection points to the RJ-45 (which operates at a maximum of 500MHz with pins 1, 2, 7, and 8 working) and works with all eight pins 1, 2, 3, 4, 5, 6, 7, and 8, allowing for a maximum transmission of 2000MHz. What should be noted for Cat7/Super Cat7 double-shielded Ethernet cables that use fully shielded cables? Shielding is only effective when the entire cable has shielding devices and is properly grounded. Therefore, the entire system must consist of shielded devices, including cables, sockets, connectors, and patch panels, and the building must have a good grounding system.
