Benefit from the very high transfer speed: the Primewire CAT 8.1 network cable (8.1 standard, Class 1) provides an impressive speed of up to 40 Gbps. The ribbon cable is flexible and dimensionally stable and therefore the first choice for simple and visually inconspicuous installation. Ideal for 10/ 100/ 1000/ 10000/ 25000/ 40000 MBit Ethernet networks. The RJ-45 connectors are equipped with a kink protection sleeve and a locking lever and form a continuous shielded unit with the cables. The CAT 8.1 standard calculates the crosstalk generated by an RJ45 connector due to the design of the receiver. In this way, the CAT 8.1 standard with the RJ45 connector achieves a higher transmission speed than Cat 5 Cat 6 Cat 7 | Cat.5 Cat.6 Cat.7. Construction: Ethernet cable with twisted pairs in metal foil (PiMF) for protection against electromagnetic interference. High quality copper inner conductors and gold-plated contact surfaces. Compatible with all devices with RJ45 network connection and backwards compatible with other CAT variants, e.g. Cat.5 / Cat.5e / Cat.6 / Cat.6a / Cat.7 Ideal for all hardware components with LAN connectivity: PCs, notebooks, laptops, modems, DSL routers, switches, network cameras, network printers, servers, game consoles, smart TVs, media players, surround amplifiers, Internet radios and much more. Also perfect for the Playstation PS5 and Microsoft Xbox Series X and S.
