Pros & Cons

Pros

  • ✓ 2000MHz bandwidth rating, 40Gbps ceiling - well above Cat6 and Cat5e
  • ✓ Four pairs of 100% pure copper with S/FTP shielding against EMI/RFI
  • ✓ 24K gold-plated RJ45 contacts resist corrosion on long-term installs
  • ✓ UV-resistant PVC jacket rated for sun, cold, humidity, and burial

Cons

  • ✗ Flat design cannot be terminated in a keystone jack like round solid-core
  • ✗ 20FT fixed length - no in-line coupler included for longer runs
  • ✗ Cat8's 40Gbps needs 40GbE NICs and switches most homes don't own
  • ✗ Flat cables kink at sharp corners despite the 10,000-bend rating

Manufacturer description

The Qiuean Cat8 Ethernet cable gives you a 20-foot run rated to 2000MHz and 40Gbps, well past the ceiling of the Cat6 and Cat5e patch cords most routers ship with. Inside the flat jacket are four twisted pairs of 100% pure copper in an S/FTP shield, which is the part that matters when your cable runs alongside power lines, surge strips, or a rack full of gear throwing off EMI and RFI. The RJ45 ends are 24K gold-plated to resist corrosion over long installs. The flat profile makes this easier to route than round Cat8 under carpet edges, along baseboards, or behind a desk, and the connector is…

SpecPicks Verdict

SpecPicks scored Cat8 Ethernet 20FT Cable 40Gbps 2000MHz Flat SFTP Gold Plated RJ45 using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. Qiuean's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Will a Cat8 cable make my home internet faster?

No. Cat8's 2000MHz and 40Gbps ratings are ceilings, not boosts. If your plan is 1Gbps, this cable delivers the same speed as a good Cat6. It buys headroom for future 2.5G, 5G, or 10G gear and better shielding in noisy environments.

Does this work with a PS5 or Xbox?

Yes. It uses a standard RJ45 connector and is backward compatible with Cat7, Cat6, Cat6e, Cat5e, and Cat5, so it plugs into the PS5, PS4, PS3, Xbox, smart TVs, routers, modems, switches, and patch panels without adapters.

Can I run this outside or bury it?

The manufacturer rates the thickened PVC jacket as weatherproof and UV-resistant against direct sunlight, extreme cold, humidity, and heat, and states it is robust enough for direct burial. For code-regulated or conduit installs, confirm local requirements before running it.

Why is the cable flat instead of round?

The flat jacket routes under carpet edges, along baseboards, and behind furniture where round Cat8 bulges. It is rated for over 10,000 bends. The tradeoff is that flat stranded cable is meant for patch runs, not punchdown into keystone jacks.

How is this shielded against interference?

It uses four pairs of 100% pure copper in an S/FTP construction, meaning each pair is foil-shielded inside an overall braided screen. That is what suppresses EMI and RFI when the cable runs near power cords, UPS units, or dense rack gear.

Key Features

  • CAT8 ULTRA INTERNET SPEED – This CAT8 Ethernet cable (aka LAN cable, internet cord, or network/patch cord) supports high-speed data transmission up to 2000MHz, providing seamless connectivity to LAN/WAN segments and all networking gear at maximum speed. It outperforms Cat7, Cat6e, Cat6, Cat5e, and Cat5, and measures 20 feet in length.
  • DURABLE & STABLE – This heavy-duty Ethernet cord is constructed with 4 pairs of 100% pure copper S/FTP shielded twisted wires, effectively minimizing EMI/RFI interference. The 24K gold-plated RJ45 connector guarantees corrosion resistance and sustained performance, eliminating noise and signal loss.
  • UNIVERSAL COMPATIBILITY – This flat network cable is backward compatible with Cat7, Cat6, Cat5, and Cat5e standards. It offers universal connectivity for routers, smart TVs, modems, ADSL, switches, patch panels, gaming consoles like PS3, PS4, PS5, Xbox, and any other device with an RJ45 port – making it an ideal gaming LAN cable or PS5 Ethernet cable.
  • WEATHERPROOF & UV-RESISTANT – This LAN cable features a durable PVC jacket that withstands direct sunlight, extreme cold, humidity, and hot weather while keeping stable performance. This sturdy Cat8 patch cord can be bent over 10,000 times, making it ideal for both indoor and outdoor installation – perfect as an outdoor Ethernet cable.
  • ENVIRONMENTAL PVC OUTER – The thickened, eco-friendly PVC outer layer effectively protects the internal core wires from physical damage, offering excellent abrasion resistance and bending durability. This patch cable is robust enough to be buried directly in the ground for permanent outdoor installations.
