LEONI Kerpen LEONI F6-90 S/F H Kat.6A 20 m harmaa

Engineered for 10 Gigabit Ethernet over 20 metres with a 500 MHz bandwidth, this LEONI Kerpen Cat.6A cable delivers headroom for high-density data centre and office cabling. The S/FTP construction—each pair aluminium-foil shielded plus an overall tinned-copper braid—virtually eliminates alien crosstalk, ensuring error-free transmission even in bundles.

Overview

The LEONI Kerpen F6-90 is a premium augmented Category 6 network installation cable built to ISO/IEC 11801, EN 50173 and TIA/EIA-568-C.2 standards. Its 23 AWG solid bare copper conductors provide low attenuation and excellent conductivity, while the LSZH jacket meets IEC 60332-1-2 flame retardancy for safe use in public and commercial spaces. With a nominal outer diameter of 7.5 mm, it balances flexibility with robust shielding.

What stands out

• Full 10GBASE-T support up to 100 m channel length (this 20 m segment ideal for patching or short runs).
• Double shielding: PIMF foil per pair + overall copper braid for superior EMI/RFI immunity.
• LSZH jacket emits low smoke and zero halogen in fire, protecting people and equipment.
• Solid bare copper conductors ensure consistent performance and support Power over Ethernet (PoE) applications.
• Wide operating temperature range from -20°C to +60°C suits both indoor and protected outdoor use.
