Cat8 Flat Cable

The eight-category flat cable (Cat8 Flat Cable) is a high-performance dual-shielded Ethernet cable with a flat design that complies with the ANSI/TIA-568.2-D and ISO/IEC 11801 Class I standards. Its core advantages include ultra-thin and easy-to-hide design + 2000 MHz bandwidth + 40 Gbps transmission + strong anti-interference. It is specifically designed for short-distance high-speed network connections and is suitable for gaming, 40G audio/video / storage, and neat wiring scenarios. Compared to the circular eight-category cable, its long-distance stability is slightly weaker, making it more suitable for short-distance applications that require both high-speed performance and concealed wiring.

1. Basic Definition and Core ParametersStandard Specification: Complies with ANSI/TIA-568.2-D Cat8 and ISO/IEC 11801 Class I standards, supporting 25GBASE-T/40GBASE-T 10 Gigabit / 40 Gigabit Ethernet
Transmission Performance: Bandwidth 2000 MHz, supports 40 Gbps transmission rate (≤ 30 meters), 10 Gbps support up to 100 meters
Shielding Structure: Mainly S/FTP dual shielding (each pair of twisted wires is independently aluminum foil shielded + overall metal braided net shielded), some high-end models adopt U/FTP or SSTP triple shielding design, effectively resisting EMI/RFI interference
Common Specifications: Conductors are mostly 24-26AWG non-oxygenated copper, wire diameter about 2.5mm thick × 9mm wide, common outer skin is PVC / low smoke halogen-free (LSZH), 8-core 4-pair twisted wires are arranged side by side
Interface Type: Both ends equipped with metal-enclosed RJ45 crystal head (often 50μm gold-plated contacts), ensuring continuous shielding and oxidation resistance
Compatibility: Downward compatible with all devices and application scenarios of Cat5/5e/Cat6/Cat6a/Cat7, physical interfaces are universal
