Category 8 (CAT8) Cables

Buy NEW 40-Gigabit Ethernet Certified Category-8 (CAT8) Network Patch Cables Factory-Direct from one of the Largest Interconnect Companies in the World: Amphenol.  Amphenol's innovative Shielded Twisted Pair (STP) Category-8 (CAT-8) Ethernet Cables offer IT and Network Engineering specialists the most technologically-capable and truly "future-proof" Ethernet Cabling interface standard ever brought to market, sporting an impressive projected service life of at least 30-years!


CAT8 Ethernet Cable assemblies from Amphenol Cables on Demand (https://CablesOnDemand.com) combine full TIA/EIA certification for blazing fast 40GBASE-T (40G Ethernet over Twisted Pair) and/or 25GBASE-T (25G Ethernet over Twisted Pair) network throughput over links up to 30-meters (~100-feet) in length.  We utilize the Fluke CAT8 40GBASE-T channel test for 40-Gigabits-per-second aggregate link throughput (10G x 4 lanes = 40G total) confirmation, aided by a broad-spectrum analog domain signal sweep to 2000-MHz (2-Gigahertz).


Category-8's 2000MHz bandwidth capacity is impressive -- offering a massive 4X bandwidth improvement over its CAT-6a predecessor (500MHz nominal).  CAT-8 Ethernet Cables from Amphenol Cables on Demand are currently available in numerous cable lengths to meet your application requirements.  Even if you aren't running 25G/40G Ethernet RJ45 hardware yet, investing in our reverse-compatible CAT8 Cables now will deliver superior performance with your current 10GBASE-T LAN, thanks to its superior reduction in Bit-Error-Rate (BER). 


While there certainly is a price premium with CAT8, comparable performance can only be had through the use of far more costly 25G Ethernet SFP28 and 40G Ethernet QSFP+ based interconnects.  These would include products such as SFP28/QSFP+ Direct Attach Copper (DAC) Cables, Optical Transceiver Modules, or Active Optical Cables (AOC). These options will easily run up to 10X the price of CAT8 and take up far more valuable real-estate from a wire-management perspective.
