Manufacturer description
The 10Gsupxsel Cat8 Flat Ethernet Cable gives you 50 feet of shielded wired networking in a profile just 2.7mm thick.

Frequently Asked Questions
Will this Cat8 cable make my internet faster than 1Gbps?
The cable is rated for up to 40Gbps, but your actual speed is capped by the slowest part of the connection: your internet plan, router port, switch and your device's network adapter. With 1Gbps or 2.5Gbps ports, it runs at that port's speed.
Is it thin enough to run under a door or carpet?
Yes. The flat cable is 2.7mm thick, so you can run it under carpets and doors, behind furniture and along baseboards and walls.
Can I plug it into several ports on a crowded router or switch?
Yes. It uses narrow RJ45 plug molds, so you can seat several cables side by side in routers, Ethernet switches and PCs without the plug housings getting in each other's way. The slim plugs can also pass through conduit.
Can I use this Ethernet cable outdoors?
The listing describes it as an indoor and outdoor cable, but it doesn't give a UV-resistance or direct-burial rating. Check the product listing before exposing it to long-term sun or burying it.
Does it work with devices that have regular Ethernet ports?
Yes. It uses standard RJ45 connectors, so it plugs into the Ethernet ports on routers, switches, PCs, consoles and smart TVs. The link runs at whatever speed the connected hardware supports.
