Cat8 Cable 400ft S/FTP Shielding

This 400-foot Cat8 Ethernet cable uses S/FTP construction with bare copper conductors to deliver 40Gbps throughput at 2000MHz bandwidth. Gold-plated RJ45 connectors ensure reliable contact with routers, switches, consoles, PCs and smart TVs. The heavy-duty PVC jacket resists weather, abrasion and repeated bending for indoor or outdoor runs.

40Gbps 2000MHz Capacity and Limits

The cable comfortably handles server links, cloud storage sync, 4K streaming and competitive gaming across its full 400-foot length. Performance runs out when the installed run exceeds the 400-foot distance or when connected equipment cannot negotiate 40Gbps speeds. Backward compatibility with Cat6, Cat5e and Cat5 keeps older gear working at their rated limits.

Cat8 Standard Practical Constraints

Cat8 is defined for channels up to 40 metres, so a 400-foot run exceeds the standard channel length and may not achieve certified 40Gbps performance at the far end. Shielded S/FTP design reduces EMI, RFI and alien crosstalk, but grounding both ends is required for full benefit. The thick PVC sheath adds stiffness that makes tight bends and dense patch panels harder to manage.

Questions about this item

Will this 400Ft Cat8 cable work with my existing Cat6 router and older PS3 without rewiring?

Yes — the cable is backward compatible with Cat6, Cat5e and Cat5, and its gold-plated RJ45 connectors fit standard router, modem and console ports including PS3 and PS4.

How can I verify the link is running at the rated 40Gbps and 2000MHz after I install the cable?

Check the negotiated speed in your router or PC network adapter settings; a 40 Gbps link should be reported when both ends support Cat8, and the S/FTP shielding with bare copper pairs keeps signal integrity at 2000 MHz.

Does the 400Ft reel include RJ45 plugs on both ends or do I need to buy connectors and a crimping tool separately?

The cable comes with gold-plated RJ45 connectors already fitted on both ends, so no separate plugs or crimping tool are required for installation.
