5m Ethernet cable underground CAT 7 Double jacket

CAT 7 direct burial Ethernet for outdoor data installations

This professional CAT 7 direct burial cable is designed for high-speed, interference-resistant data transmission in outdoor and underground installations. Whether you're networking remote buildings, powering IP devices in the garden, or installing infrastructure across industrial sites — this CAT 7 underground cable offers long-term durability, stable performance, and complete weather resistance.

Its S/FTP shielding (screened foiled twisted pair) ensures each pair is individually foil-shielded with an overall braid — making it a top choice where EMI protection is critical. Built with solid bare copper (AWG23/1) conductors, this underground Ethernet cable supports frequencies up to 1000 MHz and speeds up to 10 Gbit/s, making it ideal for future-proof networking in demanding direct burial installations.

The double jacket cable design combines a flexible PVC inner sheath and a rugged, UV- and moisture-resistant LLDPE outer jacket. Together, they deliver excellent protection against soil contact, mechanical pressure, and seasonal extremes. Fully rated as direct burial CAT 7, this cable can be laid directly in the ground without additional conduit in most standard environments.

Applications – Where This Cable Excels

Connecting buildings on commercial or residential properties
Outdoor IP cameras, smart gates, access control units
Garden offices, garages, sheds, and smart home systems
Industrial connections to warehouses, machines, or solar setups
Hybrid runs with direct burial coaxial cable and Ethernet for AV/data transmission

Features – Field-Proven Insights for Professionals

LLDPE jacket holds up in trench moisture. Unlike softer PE blends, this direct burial network cable features an LLDPE outer sheath that resists swelling and surface cracking even in permanently damp soil, ensuring long-term reliability in underground environments.
Shielding layout reduces crosstalk in long parallel runs. The S/FTP structure doesn’t just block external EMI — it also keeps internal pair-to-pair crosstalk low over long distances, especially in ducts or multi-cable bundles. Installers working with parallel Cat 7 runs will notice significantly cleaner signals on scope testing.
Pairs are tightly twisted and uniform. This one’s consistent — verified with TDR. You get predictable performance, even under load.
Outer sheath strips clean with no foil snag. The cable jacket doesn’t fuse to the inner foil, which is a real time-saver when terminating dozens of ends. You won’t spend minutes per cable fighting adhesive-bonded layers.
Performs better than spec in most real-world 10G runs. Lab tests are one thing — real trench runs with minor bends, pressure, or inconsistent soil are another. This direct burial data cable handles suboptimal routing and still pushes full 10G across 80–90 meters with solid headroom, even on unbalanced ground conditions.

Conclusion – Expert Insight

For outdoor and underground networking where long-term reliability matters, this CAT 7 direct burial cable offers a well-balanced combination of shielding integrity, mechanical durability, and high-frequency performance. With solid copper conductors and a dual-layer jacket built for environmental stress, it's a dependable choice for installations where cheap cabling simply won’t last — whether in residential interconnects, outdoor IP systems, or industrial Ethernet. This is the kind of cable you install once and don’t need to think about again — making it one of the best direct burial Ethernet cables available for long-term outdoor use.
