Amphenol Cables on Demand CAT8 Shielded Twisted Pair (STP) Shielded Network Patch Cables are designed for 25Gbps or 40Gbps speeds at link distances up to 30m. These cables use CAT8 ISO/IEC shielded RJ45 connectors to offer a 50% reduction in Near End Cross Talk (NEXT). The CAT8 STP cables offer headroom for 10Gigabit Ethernet (40GBASE-T) and an X-web pair separator for resistance to cross-talk. These cables feature 100Ω impedance, 17.89Ω/100m maximum conductor DC resistance, and 5600pf/100m capacitance. These cables are available in multiple lengths and colors. The CAT8 STP cables are certified to TIA/EIA-562-B.2-10 specifications and are CAT6 and CAT5e compatible.
