DbillionDa Cat 8 Ethernet Cable 40Gbps 2000MHz
Bottom line: The DbillionDa Cat 8 Ethernet Cable 40Gbps 2000MHz ($62.99 on Amazon as of 2026-10-20 22:15 UTC): 40 Gbps at 2000 MHz leaves headroom over 10GbE gear; main trade-off: 100 ft is overkill for a desk-to-router run; excess coils up.

Pros & Cons
Pros
- ✓ 40 Gbps at 2000 MHz leaves headroom over 10GbE gear
- ✓ 26AWG oxygen-free copper conductors, not copper-clad aluminum
- ✓ Shielded twisted pairs plus shielded RJ45 ends cut crosstalk
- ✓ Weatherproof, UV-resistant jacket rated for outdoor runs
Cons
- ✗ 100 ft is overkill for a desk-to-router run; excess coils up
- ✗ Cat8 speeds need 40GbE hardware most homes do not own
- ✗ 26AWG shielded cable is thick and stiff to route through walls
- ✗ Shielded cable needs grounded gear to realize its full benefit
Manufacturer description
The DbillionDa Cat 8 ethernet cable runs a full 100 feet of 26AWG oxygen-free copper between your router and your rig, and it is built for the runs most patch cables cannot handle. Rated for 2000 MHz bandwidth and 40 Gbps throughput, it gives you headroom well past what a multi-gig home connection or a 10GbE switch will ask of it, so the cable is never the bottleneck. Shielded twisted pairs (STP) and shielded RJ45 connectors on both ends keep crosstalk and outside interference off the line, which matters when the run passes near power cables, fluorescent fixtures, or a crowded server closet…
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. 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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Will this cable make my internet faster?
Only up to what your service delivers. The 40 Gbps, 2000 MHz rating removes the cable as a bottleneck, but your actual speed is capped by your ISP plan and your router. It matters most for local transfers between a NAS, a switch, and a PC.
Can I run this outside or bury it?
The jacket is weatherproof and UV-resistant and DbillionDa rates the cable for indoor and outdoor use. Direct burial is not stated in the product listing, so check with the manufacturer before trenching it underground.
Does it work with my Cat6 router and older devices?
Yes. It is backward compatible with Cat7, Cat6, Cat6e, Cat5e, and Cat5 networks and terminates in standard RJ45, so it drops into existing routers, modems, switches, and patch panels without adapters.
Will it work with a PS5 or Xbox?
Yes. DbillionDa lists PS3, PS4, PS5, and Xbox among supported devices, along with smart TVs, iMacs, PoE devices, and anything else with an RJ45 port.
What is in the box and what support comes with it?
One 100 ft Cat8 ethernet cable. DbillionDa includes 30-day money-back support plus ongoing customer service. Check the product listing for current warranty terms beyond that window.
