UNITEK C18121BL Cat.-6A-S/FTP-LSZ-asennuskaapeli, 305 m, sininen

10 Gigabit Ethernet over 305 metres of pure copper — this UNITEK C18121BL Cat. 6a S/FTP cable is built for high-density, high-speed structured cabling where performance and safety are non-negotiable. The screened/foiled twisted pair construction and LSZH jacket make it the go-to choice for data centres, offices, and public buildings.

Overview

The UNITEK C18121BL is a bulk Cat. 6a network cable supplied on a convenient reel, ready for professional installation. With S/FTP shielding — an overall braided screen plus individual foil per pair — it provides superior immunity to electromagnetic interference (EMI) and alien crosstalk, ensuring stable 10GBASE-T transmission up to 500 MHz. The low-smoke zero-halogen (LSZH) jacket emits minimal smoke and no toxic halogens in case of fire, meeting strict safety standards for enclosed spaces.

What stands out

• 10 Gigabit Ethernet support with 500 MHz bandwidth for demanding applications.
• S/FTP shielding: braided screen plus per-pair foil for maximum noise rejection.
• LSZH jacket: low smoke, zero halogen, flame retardant — safer for people and equipment.
• Pure copper conductors (23 AWG) ensure excellent conductivity and signal integrity.
• 305 m reel: ideal for large installations, reducing waste and splices.
• Compliant with TIA/EIA-568-C.2, ISO/IEC 11801, and RoHS; CPR classification Eca.
