Pros & Cons

Pros

  • ✓ Rated up to 40Gbps and works with 10/100/1000 Mbps networks
  • ✓ 2000MHz bandwidth for 4K streaming, online gaming and large file transfers
  • ✓ S/FTP shielding plus a tinned-copper ground line to reduce EMI
  • ✓ Oxygen-free copper core with gold-plated, corrosion-resistant RJ45 plugs

Cons

  • ✗ 100 ft is slightly longer than the 30 m run Cat 8 specifies for 40Gbps
  • ✗ Most home routers and NICs max out at 1-10Gbps, so the 40Gbps goes unused
  • ✗ Heavy S/FTP shielding makes it thicker and stiffer to route than Cat 6
  • ✗ No in-wall (CMR/CMP) or outdoor rating listed

Manufacturer description

The Cablism Cat 8 Ethernet Cable gives you 100 feet of shielded network cable rated for data rates up to 40Gbps and 2000MHz of bandwidth. It works with 10, 100, 1000, 10000 and 25000 Mbps Ethernet, so it runs with the router, switch or network card you already own and leaves room for faster gear later. Inside, oxygen-free copper conductors carry the signal. The S/FTP build shields the twisted pairs and wraps the whole bundle in an outer shield. A tin-plated copper grounding line helps cut electromagnetic interference, which matters when the cable runs past power cords, monitors or other…

Frequently Asked Questions

Will this Cat 8 cable work with my 1Gbps router or older network gear?

Yes. Cablism lists support for 10, 100, 1000, 10000, 25000 and 40000 Mbps Ethernet. It fits any standard RJ45 port. Your connection runs at the top speed of your slowest device.

Will I actually get 40Gbps over the full 100 feet?

The cable is rated for up to 40Gbps and 2000MHz. The Cat 8 standard specifies 25/40GBASE-T for runs up to 30 m (about 98 ft), and very little home equipment supports 40Gbps. For most setups, expect the full speed of your router or switch, usually 1 to 10Gbps.

Is this Ethernet cable shielded against interference?

Yes. It uses S/FTP construction, which shields the twisted pairs and adds an outer shield. It also has a tin-plated copper grounding line and oxygen-free copper conductors to reduce EMI and resist oxidation.

Can I run this cable inside walls or outdoors?

The product listing does not state an in-wall (CMR/CMP) fire rating or an outdoor/UV rating. Check the listing or contact Cablism before installing it inside walls or outdoors. Otherwise, use it as an indoor patch cable.
