Category 8 (CAT-8) Ethernet Cables

Buy NEW 40-Gigabit Ethernet Certified Category-8 (CAT-8) 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!


CAT-8 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 CAT-8 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 CAT-8 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 CAT-8, 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 CAT-8 and take up far more valuable real-estate from a wire-management perspective.
