Cat 6 Ethernet Cable Outdoor 400ft - Shielded, Direct Burial

Our review of the Cat 6 Ethernet Cable Outdoor 400ft examines whether this heavy-duty bulk cable is the right choice for long outdoor runs and demanding network environments. The bottom line: this cable is best for homeowners, installers, or small IT teams who need a long, shielded Cat 6 run that can be buried or routed outdoors without frequent replacement, because its PVC jacket, FTP shielding and 23AWG conductor provide weather resistance and stable signal performance for LAN, router, and outdoor camera links.

Key Features

• Outdoor rated jacket: The durable PVC outer jacket offers UV, water, tensile and compression resistance so the cable holds up to sun exposure and wet conditions.
• Shielded construction (FTP): Foil shielding reduces EMI and crosstalk, which helps preserve signal quality in areas with electrical interference.
• 23AWG conductors: Thicker 23AWG single-core CCA gives a higher bandwidth margin and more stable data transfer than typical 24/26AWG stranded cables.
• Direct burial capable: Built for direct burial with a cross-shaped internal separator and reinforced structure to protect conductors during bends and underground runs.
• Bulk kit with connectors: The 400ft spool includes 20 gold-plated RJ45 connectors so the cable can be cut to custom lengths without buying additional plugs.
• Weatherproof design: Multi-layer protection including insulating plastic and tensile cords helps the line tolerate extreme heat, cold and moisture for longer service life.

Who It's For

This cable suits homeowners or small offices running long outdoor Ethernet runs to routers, security cameras, or backyard access points where burying cable or exposure to weather is required. Installers and DIYers who want a single long spool they can cut to size will also appreciate the included RJ45 plugs.

Those who require true copper conductors for maximum PoE performance should look elsewhere, since this product uses 23AWG CCA conductors and is not recommended for PoE. Also, environments that demand ultra-flexible patch cords for frequent movement would be better served by stranded indoor patch cables.

Pros & Cons

Pros

• Robust PVC jacket and internal reinforcement make it suitable for direct burial and outdoor exposure.
• Shielded FTP design reduces EMI and improves reliability in noisy environments.
• 23AWG conductor offers greater bandwidth margin and stable connections over long runs.
• Bulk 400ft spool with 20 RJ45 connectors allows custom length cuts and flexible installations.

Cons

• Uses copper-clad aluminum (CCA), so it is not recommended for powering devices via PoE and may not match pure copper performance in all scenarios.
• Some customers reported mixed feedback on long-term cable or connector durability in certain installs.

Our Verdict

For anyone who needs a long, shielded outdoor Cat 6 run at a reasonable price, this 400ft direct burial spool is a practical choice because of its weatherproof jacket, FTP shielding and thicker 23AWG conductors. It represents good value for outdoor LAN and router connections, but installers should avoid PoE device feeds and be mindful of mixed reports about long-term connector or cable degradation in some installs.

Frequently Asked Questions

Can this cable be buried directly in the ground?
Yes, it is specified for direct burial with a reinforced jacket and internal structure designed to protect the conductors when buried.

Does this cable support PoE for cameras and access points?
The manufacturer notes this cable is not recommended for PoE due to its CCA conductor construction, so use a pure copper cable if PoE is required.

Are connectors included so the cable can be cut to length?
Yes, the spool includes 20 gold-plated RJ45 connectors so you can cut custom lengths and terminate runs without buying extra plugs.
