Cat 8 Ethernet Cable 100FT - High Speed 40Gbps Flat LAN Cable

In this review of the Cat 8 Ethernet Cable 100FT the bottom line is simple: this cable is for anyone who needs a long, high-performance wired connection and wants a flexible, easy-to-route solution. The standout reason to buy is its combination of very high bandwidth capability and a flat, low-profile design that makes long runs along baseboards or under carpets unobtrusive. The reviewer found the cable's build quality and shielding deliver steady signal quality for streaming, gaming and linking network gear across floors without the clutter of bulky round cables.

Key Features

• 40Gbps data speed: Supports very high transfer rates for local network use so large file transfers and high-bandwidth streaming remain smooth.
• 2000MHz bandwidth: The 2GHz rated bandwidth helps maintain clean signal headroom for demanding LAN tasks and future-proofing on compatible equipment.
• S/FTP shielding: Full foil and braided shields with shielded twisted pairs reduce crosstalk and external interference for consistent signal quality.
• Gold-plated RJ45 connectors: 50 micron gold contacts resist corrosion and sustain reliable connections over repeated plugging and long-term use.
• Flat, flexible jacket: Thin 26AWG flat design makes the cable easy to hide along walls, under carpets or through tight routing paths without kinking.
• Durable construction: Soft PVC jacket and oxygen-free copper conductors increase longevity and resist abrasion and environmental effects.

Who It's For

This cable suits homeowners and small-office users who need a long, high-bandwidth Ethernet run - for example linking a router to a distant switch, connecting a gaming rig, or running a stable feed to a streaming box. The 100ft length is especially useful for linking devices across rooms or floors while keeping a neat install with the flat profile.

Those who should look elsewhere include users who only need short patch cords or who require plenum-rated cabling for in-wall commercial installations; this cable is built for flexible indoor and outdoor routing but does not replace specialized in-wall plenum or riser-rated wiring requirements.

Pros & Cons

Pros

• Very high bandwidth and speed capability provide headroom for fast LAN transfers.
• Flat, flexible design makes long runs tidy and easy to conceal along edges and under carpets.
• Robust shielding and gold-plated contacts deliver stable signal quality and resist interference.
• Durable materials and thick conductors suggest a long service life for home networking.

Cons

• Not a substitute for plenum-rated in-wall cables required by some building codes.
• The full 40Gbps speed requires compatible hardware; many home setups will operate at lower negotiated speeds.

Our Verdict

The Cat 8 100ft flat Ethernet cable is a strong value for users who need a long, reliable wired run with excellent shielding and future-proof bandwidth. It is especially good for tidy indoor routing and high-speed LAN tasks; buyers should just confirm it meets any required in-wall ratings before using it for concealed permanent building wiring.

Frequently Asked Questions

Can this cable support gigabit internet?
Yes, the cable easily supports 1Gbps connections and offers much higher headroom up to 40Gbps when paired with compatible equipment.

Is the flat design easy to hide under carpets?
Yes, the flat and flexible jacket is designed to be routed along edges and under carpets for a cleaner installation.

Is this cable suitable for outdoor use?
The cable's PVC jacket provides resistance to abrasion and UV to tolerate outdoor runs, but it is not a replacement for specialized direct-burial rated cables for prolonged underground installation.
