Cat8 Ethernet Cable 100 ft - High Speed 40Gbps, Shielded

In this review of the Cat8 Ethernet Cable 100 ft, the bottom line is simple: this cable is for users who need a long, shielded wired connection that supports very high bandwidth and stable performance. The reviewer found the cable especially useful for demanding wired setups where WiFi is inconsistent, and appreciated that the product supports up to 40 Gbps transfer rates and a wide 2000 MHz bandwidth. It is a practical choice for homes or small offices that run devices at wired speeds, and for anyone replacing older Cat5/6 runs with a future-proofed, shielded option.

Key Features

• Length and reach: The 100 ft run gives room to route from a modem or router to distant devices without relying on extra extenders or switches.
• Top speeds: With support for up to 40 Gbps and 2000 MHz bandwidth, the cable handles large file transfers and low-latency gaming where link speed matters.
• Shielded construction: The F/FTP design with shielded RJ45 connectors reduces interference for more consistent connections in noisy environments.
• Durable materials: Built with 100% oxygen-free copper and eco-friendly jacket materials for a thinner but robust cable that lasts longer than many Cat7 alternatives.
• Backward compatibility: Fully compatible with Cat6, Cat6e, Cat5 and Cat5e devices, making it a straightforward upgrade without swapping network hardware.

Who It's For

The cable is best for users who need a long, high-bandwidth wired link: gamers using PS4/PS5 or Xbox in another room, media centers and smart TVs, desktop PCs or iMacs doing large transfers, and small office networks that benefit from shielded runs. It is also suited to anyone who wants to preserve or improve wired internet speeds and reduce packet loss compared with wireless alternatives.

Those who should look elsewhere include casual users who only need short connections or who rely exclusively on WiFi, and installers who require plenum-rated or in-wall certified cable specific to building codes, since this product is presented primarily as an indoor/outdoor shielded Ethernet solution rather than specialized building-cable certification.

Pros & Cons

Pros

• Supports very high transfer rates up to 40 Gbps for demanding network tasks.
• Shielded F/FTP design and gold-plated RJ45 connectors give reliable connections and lower interference.
• 100 ft length provides flexible routing options without extra hardware.
• Backward compatibility makes it easy to upgrade older network devices.

Cons

• Not described as in-wall or plenum rated, so may not meet specific building installations.
• Some users reported mixed connectivity experiences depending on their network equipment, so results can vary with upstream hardware.

Specifications

Our Verdict

The Cat8 Ethernet Cable 100 ft is a strong value for anyone needing a long, high-performance wired connection. It combines sturdy, shielded construction with very high bandwidth and broad device compatibility, making it a good upgrade for home power users, gamers, and small offices. For those who need code-certified in-wall cable, check installation requirements first, but for standard runs this cable delivers notable speed and stability improvements.

Frequently Asked Questions

Will this cable work with my Cat6 router?
Yes. The cable is fully backward compatible with Cat6, Cat6e, Cat5 and Cat5e devices and will operate at the maximum supported speed of the connected hardware.

Is this cable suitable for outdoor use?
The cable is described for indoor/outdoor use, but if permanently exposed to harsh weather or buried, follow local guidelines and consider additional protection to extend life.

Does it improve internet speed on its own?
Cable quality can reduce interference and improve link stability; actual internet speed gains depend on your ISP plan and connected equipment, though many users report noticeable improvements over older cables.
