Unlock next-generation networking with our high-speed CAT8.1 Dual-Shield Ethernet Cable, engineered for 25–40 Gb/s performance in data centers, enterprise trunks, and fire-critical environments. Featuring advanced S/FTP double shielding (foil per pair + overall braid), premium heavy-duty 23 AWG solid bare copper conductors, and a low-smoke zero-halogen (LSZH) jacket, this shielded CAT8 cable ensures EMI/RFI resistance, low attenuation, and safe installation for indoor or conduit-grade outdoor runs up to 30 meters. Backward-compatible with standard RJ45 connectors, it's the ideal choice for future-proof 40GBASE-T connectivity, 25GBASE-T support, PoE++ capability, and uncompromised signal integrity in data centers and confined spaces.

Designed for cutting-edge data center infrastructure, this ultra-premium cable represents the absolute pinnacle of copper Ethernet technology with seven exceptional features: CAT8.1 Class I performance (2,000MHz), S/FTP dual shielding (mandatory for CAT8), heavy-duty 23AWG conductors, LSZH jacket for environmental safety, 40GBASE-T capability up to 30m, 25GBASE-T support, and RJ45 compatibility. The S/FTP shielding provides individual foil on each pair PLUS an overall tinned-copper braid—delivering flawless 40Gb throughput in electrically noisy data center environments. Exceeding ISO/IEC 11801 Class I and ANSI/TIA-568.2-D Category 8 specifications with IEC 60332-1 compliance, it's the ultimate solution for top-of-rack to server connections, high-density racks, and any short-distance application requiring maximum copper Ethernet performance.
