Manufacturer description

The Cablism Cat 8 Ethernet Cable gives you a 25-foot (8 m) wired link rated for up to 40Gbps and 2000MHz of bandwidth.

It supports 10, 100, 1000, 10000, 25000 and 40000 Mbit Ethernet, so it works with the gigabit router you have now and leaves room if you move to multi-gig switches or NAS gear later. Inside, an oxygen-free copper core sits within S/FTP shielding (every twisted pair is individually foiled under an overall braid). A tin-plated copper grounding line reduces…

Frequently Asked Questions

Will this Cat 8 cable make my internet faster?

The cable itself is rated for up to 40Gbps, but your actual speed is limited by your internet plan, router, switch and network card. It removes the cable as a bottleneck and cuts the interference and dropouts that come with Wi-Fi.

Does it work with my Cat 6 or Cat 5e router and devices?

Yes. Cablism lists it as compatible with Cat 7, Cat 6, Cat 5e and Cat 5 equipment. It uses standard RJ45 connectors, so it plugs into any Ethernet port on PCs, consoles, routers, switches, TVs and NAS units.

Is this cable shielded against interference?

Yes. It uses S/FTP construction, with individually foiled twisted pairs under an overall shield, plus a tin-plated copper grounding line. Cablism says this reduces EMI and keeps the connection stable near power cables and electronics.

How long is the cable, and is it good for gaming?

It is 25 ft (8 m) long. The 2000MHz bandwidth rating and shielding are aimed at low-interference connections for online gaming, 4K streaming and file transfers.

What warranty comes with the Cablism Cat 8 cable?

The product listing does not state warranty terms. Check the current Amazon listing or contact Cablism directly for coverage and return details before you buy.
