Category 5 shielded network cable

I. Core Performance Definition (First clarify product Attributes to Avoid customer confusion)
The core structure of Category 5 double-shielded network cables (Cat5S /FTP) is: 4 pairs of twisted wires + aluminum foil shielding layer (FTP) + metal Braided mesh shielding layer (Braided Shield) + outer sheath. The dual shielding design makes it far exceed the single-shielded model in anti-interference and signal protection, and its performance fully complies with ISO/IEC 11801 and TIA/EIA 568-C.2 international standards. The core parameters are the same as those of ordinary Cat5 (100MHz bandwidth, 100Mbps transmission rate), but the stability in complex scenarios has been significantly improved.
Ii. Detailed Explanation of Key Performance (Sorted by the Priority of Foreign Trade Customers' Concerns)
1. Anti-interference performance: Ultimate shielding, suitable for strong interference environments (core selling point)
Performance The dual shielding layer forms a "double protection" - the aluminum foil shielding layer blocks the internal crosstalk (crosstalk) and external high-frequency electromagnetic interference (EMI) of the cable, while the metal braided mesh shielding layer further guards against low-frequency electromagnetic interference (RFI), physical impacts and signal leakage. Its anti-interference capability is 2 to 3 times that of single shielding (STP) More than five times that of unshielded (UTP).
Customer pain point solution: In strong interference scenarios such as factory workshops (where motors and frequency converters are densely distributed), near high-voltage lines, and around base stations, ordinary network cables are prone to signal packet loss and transmission interruption. The dual-shielded model can achieve "zero interference" stable transmission.
English description of foreign trade
“Dual shielding design (foil + braided) provides superior EMI/RFI resistance,  blocking interference from industrial equipment, power lines,  and wireless base stations. Anti-interference performance is 2-3x stronger than single-shielded (STP) and 5x stronger  than unshielded (UTP) Cat5 cables, ensuring no signal loss in harsh environments.”
2. Transmission stability: Low attenuation + no crosstalk, ensuring reliability in critical scenarios
Performance
Signal attenuation: Within a maximum transmission distance of 100m, the attenuation value is ≤24dB (at 100MHz frequency), which is far below the international standard threshold (≤27dB). It supports stable transmission at a rate of 100Mbps without delay or lag.
Crosstalk suppression: The dual shielding layer significantly reduces crosstalk between pairs (NEXT ≤ -32dB) and external crosstalk (AXT ≤ -35dB), making it suitable for scenarios with high requirements for "distortion-free transmission", such as voice (VoIP), video (surveillance), and industrial control instructions.
