Manufacturer description
Run a wired connection from your router to a gaming PC, console or outdoor IP camera with the DbillionDa Cat 8 Ethernet cable. This 20-foot cable is rated for 2000MHz bandwidth and data transfer speeds of up to 40Gbps.

Quadruple shielding cuts EMI and RFI interference, which helps with low-latency gaming and 4K streaming. Both ends use shielded, gold-plated RJ45 connectors. The cable works with switches, routers, modems…
SpecPicks Verdict
SpecPicks scored DbillionDa Cat 8 Ethernet Cable 40Gbps 2000MHz using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. DbillionDa's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Will this Cat 8 cable work with my Cat6 router or switch?
Yes. The DbillionDa Cat 8 cable uses standard RJ45 connectors and is fully backward compatible with Cat7, Cat6, Cat5e and Cat5 devices. The connection runs at whatever speed your slowest port supports.
Can I bury this Ethernet cable or run it outside?
Yes. The upgraded PVC jacket is waterproof, corrosion-resistant and UV-resistant, and the manufacturer rates it for direct burial as well as outdoor and indoor use in sun, humidity, heat and extreme cold.
Will I actually get 40Gbps with this cable?
The cable is rated for up to 40Gbps and 2000MHz bandwidth, but your real speed is limited by the Ethernet ports on your router, switch, modem and network card, and by your internet plan.
Does it work with PS5, Xbox and smart TVs?
Yes. It plugs into any device with an RJ45 port. The listing names PS3, PS4, PS5 and Xbox consoles, smart TVs, laptops, routers, modems, switches, IP cameras, patch panels and servers.
