The Ercielook CAT8 Ethernet Cable gives you a 20 ft run rated for 2000MHz bandwidth and data transfer up to 40Gbps, which is the headroom you want when a router-to-PC link is the last thing standing between you and a stable match. The conductor is 100% bare copper with gold-plated RJ45 connectors, wrapped in HDPE insulation and a PVC sheath, so signal loss stays low over the full 20 foot length. The flat profile is the practical selling point: an ultra-thin cable slides under carpet, tucks along baseboards, and does not coil into the knot that round cords make behind a desk.

Frequently Asked Questions

Will this cable actually give me 40Gbps?

The cable is rated for 40Gbps at 2000MHz, but real throughput is capped by your router, switch, and network adapter. On typical 1Gbps or 2.5Gbps home gear you get the full port speed with bandwidth to spare.

Is this real copper or copper-clad aluminum?

Ercielook lists 100% bare copper wire with gold-plated RJ45 connectors, HDPE insulation, and a PVC sheath.

Can I run it outside or through a garage?

It is listed as weatherproof and UV resistant, so outdoor and unconditioned-space runs are within the stated design. For buried or in-wall runs, check local code and the product listing for the applicable rating.

Will it work with my older Cat6 router?

Yes. It is backward compatible with Cat5, Cat5e, Cat6, and Cat7 equipment and plugs into standard RJ45 ports on switches, routers, modems, adapters, and patch panels.

How many people have bought and rated this cable?

It holds a 4.7 out of 5 star rating from 2,842 reviewers.
