Ltemziiy Cat 8 Ethernet Cable 50 ft

Bottom line: The Ltemziiy Cat 8 Ethernet Cable 50 ft ($32.99 on Amazon as of 2026-10-06): 40Gbps at 2000MHz bandwidth handles NAS transfers and 4K streaming with headroom; main trade-off: 50 ft is a lot of slack if your router and PC are only a room apart.

Pros & Cons

Pros

  • ✓ 40Gbps at 2000MHz bandwidth handles NAS transfers and 4K streaming with headroom
  • ✓ S/FTP shielding on all 4 twisted pairs cuts EMI on long indoor runs
  • ✓ 50-micron gold-plated RJ45 pins resist oxidation at the contact point
  • ✓ 48-strand cotton braid jacket stays tangle-resistant when coiled behind a desk
  • ✓ Ships with 30 cable clips and 2 dust covers, so no extra hardware run needed

Cons

  • ✗ 50 ft is a lot of slack if your router and PC are only a room apart
  • ✗ Cat 8's 40Gbps ceiling is wasted on the 1GbE ports in most home routers
  • ✗ Braided round jacket is thicker than flat cable and won't slide under carpet trim
  • ✗ Rated for indoor and outdoor use, but no direct-burial or conduit spec is listed

Manufacturer description

The Ltemziiy Cat 8 Ethernet Cable gives you a 50 ft run rated for 40Gbps throughput at 2000MHz bandwidth, which is the headroom you want when you are moving large files to a NAS, backhauling a server rack, or keeping a gaming PC on a wired link across the house. Four shielded twisted pairs in an S/FTP layout, paired with 50-micron gold-plated RJ45 contact pins, cut the crosstalk and EMI that plague long unshielded runs past a breaker panel or fluorescent fixture. The outer jacket uses a 48-strand cotton yarn braid, so the cable resists tangling when you coil it behind a desk and holds up in…

SpecPicks Verdict

SpecPicks scored Ltemziiy Cat 8 Ethernet Cable 50 ft using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. Ltemziiy's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

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.

Frequently Asked Questions

Will this Cat 8 cable actually make my internet faster?

Only if your hardware is the bottleneck. The cable supports 40Gbps at 2000MHz, but your real speed is capped by your ISP plan and your router's port, which is usually 1GbE or 2.5GbE. It removes the cable as a limit, not your service tier.

Is 50 feet too long to run without losing signal?

No. 50 ft is well inside standard Ethernet run lengths, and the S/FTP construction with 4 shielded twisted pairs is designed to hold signal integrity over the distance by reducing outside interference.

Does it work with my older router and Cat6 wall jacks?

Yes. Ltemziiy lists it as backward compatible with Cat7, Cat6a, Cat6, and Cat5, and it connects to any device with a standard RJ45 port, including modems, routers, switches, consoles, and smart-home hubs.

What comes in the box besides the cable?

One 50 ft Cat 8 cable, 2 dust covers that keep dirt and oxidation off the RJ45 connectors when a port is unused, and 30 cable clips for routing along a baseboard or desk edge.
