The advantages of double-armored (double-shielded) multi-pair Ethernet cables primarily lie in their interference resistance, transmission stability, and compatibility:
Interference Resistance
The double-armor design (aluminum foil + braided mesh total shielding) effectively reduces external electromagnetic interference (EMI) and radio frequency interference (RFI), making it particularly suitable for high-interference environments such as industrial environments and data centers.
Transmission Stability
The double-shielded structure reduces crosstalk between cables, ensuring stable signals over long transmission distances. This supports higher bandwidth requirements (such as 10Gbps Ethernet) and reduces bit error rates in harsh environments.
Compatibility
Compliant with IEEE 802.3bt, it is backwards compatible with legacy Ethernet cables such as Cat5e and Cat6. It also features PoE++ power supply, enabling it to power high-power devices.
