Its specific functions and advantages are as follows:
Super strong resistance to electromagnetic interference (EMI) and radio frequency interference (RFI)
The structure of double-shielded network cables is generally divided into two types:
STP (Shielded Twisted Pair) : Each pair of core wires has a shielding layer outside, and the entire cable also has a total shielding layer.
SFTP (Twisted Shielded Twisted-pair cable) : The core wires are first twisted together, then wrapped with sub-shielding layers, and finally a total shielding layer is added on the outermost layer.
This double-layer shielding design can effectively block external electromagnetic signals (such as interference generated by power lines, motors, switches and other equipment), and at the same time prevent the signal of the network cable itself from radiating outward, avoiding interference to surrounding equipment.
Compared with unshielded Category 6 network cables, its signal stability has been significantly improved in strong interference environments.
Stably support gigabit/short-distance 10-gigabit transmission
It is the same as the ordinary Category 6 network cable, with a rated bandwidth of 250MHz, and can stably support 1000BASE-T Gigabit Ethernet, with a standard transmission distance of 100 meters. Under ideal conditions, 10GBASE-T 10-gigabit Ethernet can also be supported over short distances (30-55 meters).

The difference lies in that in scenarios with severe interference, double-shielded Category 6 network cables will not experience problems such as rate reduction or packet loss due to interference, and can always maintain the nominal performance.
Adapt to complex and harsh wiring environments
Suitable for scenarios where unshielded network cables are not up to the task
Industrial scenarios: Factory workshops (close to large machines and frequency converters), industrial control system wiring, to avoid electromagnetic interference from equipment affecting data transmission.
High-density cabling environment: In the cabinets of data centers and computer rooms, when a large number of network cables are densely arranged, it can reduce crosstalk between wire pairs.
Strong current mixed wiring scenarios: In situations where parallel wiring with power lines, monitoring lines, etc. is inevitable (such as in building weak current projects), the shielding layer can isolate the electromagnetic radiation of strong current.
Outdoor or humid environments: When used in conjunction with a waterproof sheath, the shielding layer can also protect against moisture erosion to a certain extent (grounding should be noted).
Enhance network security
The shielding layer can reduce the outward leakage of signals, lower the risk of data eavesdropping and interception, and is suitable for scenarios with high requirements for data confidentiality (such as enterprise finance departments and confidential office areas).

The prerequisite for double-shielded network cables to function effectively is proper grounding treatment. If the grounding is not standardized, the shielding layer may instead become an interference source, affecting the transmission effect
