Cat. 8.1 patch cables are used for 25/40GBASE-T applications, with a transmission range of up to 30 meters and a transmission power of up to 2 GHz (four times the bandwidth of Cat. 6A). They are suitable for 25/40G Base-T Ethernet networks (40 Gigabit) and are backward compatible. The CAT 8 Channel Link is 100% tested, with an attached measurement protocol and serial number. Maximum bandwidth is 2000 MHz / 2 GHz. The new RJ45 Cat. 8 connector adheres to industry standards with 50µ gold-plated contact surfaces (PINs). This double-shielded LAN/network cable features pair wire shielding (PIMF - pairs in metal foil) and total shielding (braid). Length indication is provided on the slimline bend protection sleeve.
