The network cable (standard 8.1, class 1) allows an impressive transfer speed of up to 40 Gbit\/s. Ideal for 10\/100\/1000\/10000\/25000\/40000 Mbit Ethernet networks RJ45 connectors are equipped with zinc metal shielding and are therefore superior to older CAT6 versions. The cable and connectors form an integral shielded unit. Additionally, they offer anti-twist protection, strain relief and lever lock The CAT8.1 standard calculates the crosstalk generated by an RJ45 connector based on the design. In this way, the CAT8 standard with the RJ45 connector achieves a higher transfer speed than Cat 5 and 6 cables Double-shielded Ethernet cable with twisted conductors and premium copper internal conductors. Multiple umbrellas in one piece. Halogen-free insulation. Compatible with all devices equipped with an RJ45 network port and backward compatible with other CAT variants, e.g. Cat.5, Cat.5e, Cat.6, Cat.6a, Cat.7a Usable for PC, laptop, modem, DSL router, switch, network cameras, network printer, server, game consoles, Smart TV, media player, surround amplifier, Internet radio, etc. Note: The data is all measured manually , please allow 1-3cm error, due to the difference in light and display, there will be a certain color difference, the actual object received shall prevail.
