VIVO Waterproof 500ft Bulk Cat5e Wire, CCA Ethernet Cable

The VIVO CABLE-V011 is a bulk Cat5e option designed for longer outdoor runs. It uses copper-clad aluminum (CCA) conductors with a solid 24 AWG gauge. The exterior is moisture-resistant, supporting direct burial installations, though the shielding is not UV-rated. This makes it best suited for covered or shaded burial routes where sunlight exposure is limited. Best for budget projects requiring long bulk runs without expensive copper conductors.
- Best for: large-area installations where cost matters and direct burial is possible in sheltered zones.
- Why selected: long 500 ft roll, connector-free, waterproof shielding for underground use.
- Caution: Not UV-rated; position away from direct sun to extend life.
Cat5e Outdoor Ethernet Cable 250 Feet (Conable Store)

This Cat5e outdoor cable is built for flexible outdoor use and features a double jacket with UV-resistant LLDPE and PVC inner jackets. It is designed for in-wall, direct burial, and outdoor routing where exposure to weather is a factor. The cable supports up to 1.0 Gbps with a bandwidth of up to 350 MHz, making it compatible with standard home networks and basic office setups without needing Cat6, while remaining easy to lay due to the flexible construction.
- Best for: installations requiring UV protection and a dual jacket for longevity in outdoor exposure.
- Why selected: double jacket improves durability; suitable for direct burial and in-wall runs.
- Caution: Ensure proper burial depth and separation from electrical cables to mitigate interference risks.
Cat5e 1000 Ft. Direct Burial/Underground Cable

FiveStarCable’s Cat5e 1000 Ft bulk is a robust option for long underground networks and direct burial use. It uses copper-clad aluminum conductors (CCA) with a solid 24 AWG gauge and a double jacket designed to withstand burial conditions. The cable is rated for direct burial with a waterproof outer layer, reducing the need for conduit runs in many outdoor projects. This option is best when you need a single purchase to cover an extended network without frequent spooling.
- Best for: long underground networks where a single bulk order minimizes joints and splices.
- Why selected: long run capability and reinforced burial protection with a double jacket.
- Caution: Always confirm burial depth and local code compliance for underground cable installation.
GEARit Cat 6 Outdoor Ethernet Cable (150 ft)

GEARit’s Cat6 outdoor cable provides higher speed potential and a more robust exterior jacket compared to Cat5e options. It supports up to 10 Gbps at 550 MHz for fast data transmission and features a UV-resistant, waterproof LLDPE jacket suitable for direct burial and outdoor installations. While this is listed as Cat6, it remains compatible with Cat5e networks for backward compatibility and can future-proof outdoor runs that may upgrade to 10 Gbps somewhere down the line. Best for: networks anticipating higher throughput and staying power in outdoor environments.
- Best for: outdoor installations that may require higher bandwidth or future upgrades without changing core cables.
- Why selected: true Cat6 performance with a rugged outdoor jacket designed for direct burial.
- Caution: Higher cost and larger conductor capability than Cat5e; verify device compatibility for 10 Gbps at required distances.
Buying Guide
What to consider before buying underground or outdoor Cat5e/Cat6 cables:
- Direct burial suitability: Look for a double jacket or waterproof outer layer to resist moisture and soil contact. Some options are explicitly rated for direct burial, while others require conduit or protective routing.
- Conductor material: Copper-clad aluminum (CCA) offers cost savings but may have higher resistance than solid copper. For long runs or critical links, copper or better-insulated options may be preferred.
- Jacket material and UV resistance: Outdoor installs exposed to sunlight benefit from UV-resistant jackets. If the cable will be buried, UV resistance is less critical than moisture and abrasion protection.
- Bandwidth and speed: Cat5e supports up to 1 Gbps under typical conditions; Cat6 and higher can offer higher speeds at shorter distances. Choose based on current needs and future-proofing goals.
- Run length and routing: Plan run lengths to minimize splices and avoid sharp bends. Bulk spools can reduce the number of joins but require careful handling to avoid tangles.
- Installation environment: If the cable will cross roadways or areas with heavy construction, select rugged jackets and consider conduit or protective sleeves to mitigate physical damage.
- Code compliance and safety: Verify local electrical codes and installation best practices, especially for burial near electrical infrastructure or irrigation lines.
Frequently Asked Questions
- What is the difference between Cat5e and Cat6 for outdoor use? Cat6 generally offers higher bandwidth and improved performance at shorter distances, making it suitable for higher-speed requirements and future upgrades. Cat5e is typically sufficient for standard home networks.
- Is copper-clad aluminum (CCA) acceptable for direct burial? CCA is cost-effective for long runs, but it has higher resistance than pure copper. For long outdoor runs where signal integrity matters, consider copper conductors if budget allows.
- Do I need a conduit for buried Cat5e cables? It depends on local codes and soil conditions. Direct burial-rated cables often work without conduit in stable soil, but conduit provides additional protection in rocky or high-activity areas.
- Can Cat5e support PoE devices outdoors? Yes, Cat5e supports PoE within supported power and distance limits. Verify power requirements and cable length for your specific devices.
- How long can a Cat5e cable run be before signal degradation? For standard Ethernet, a Cat5e run is typically limited to 100 meters (328 feet) without active repetition. Longer outdoor runs may require repeaters or fiber-to-CAT5e solutions.
- Which option is best for a long underground network? The 1000 ft direct burial cable from FiveStarCable Store provides a long-run solution with burial protection, reducing the number of joints needed.
In summary, the best underground Cat5e cable depends on your project scope. For long, budget-conscious bulk runs, consider the VIVO 500 ft or 1000 ft variants, bearing in mind the lack of UV rating on the shielding. If UV exposure is a concern, the Conable outdoor Cat5e with a dual jacket provides better weather protection. For higher-speed outdoor needs, the GEARit Cat6 option offers future-proofing, while the 250 ft VIVO or FiveStarCable bulk options serve mid-range outdoor burial tasks well.
