Woods 0345 24/4 Phone Wire, Direct Burial
Woods offers a long 500-foot spool of 24/4 direct burial phone wire, suitable for establishing a buried landline or low-voltage network run. The wire’s AWG size supports multiple phone lines, and the product carries UL444 and NEC Article 725 Type CM approvals, indicating compliance with safety and installation standards for underground use. The gray jacket helps blend with typical outdoor environments, and the length provides flexibility for larger properties or multiple terminal points.
Ultra Spec Cables 50ft Outdoor Phone Cable RJ11/RJ12 Direct Burial (Shielded)
This 50-foot shielded outdoor phone cable supports RJ11 and RJ12 configurations, allowing 2 or 3 phone line options. The shielded connectors help minimize electromagnetic interference in outdoor environments, and the direct burial design enables underground installation without extra conduit. Its black jacket provides weather resistance suitable for exposed settings, making it a practical choice for outdoor phone network extensions.
Ultra Spec Cables 25ft Outdoor Phone Cable RJ11/RJ12 Direct Burial (Shielded)
The 25-foot shielded option provides a compact solution for shorter runs or secondary lines. Shielded RJ12/RJ11 compatibility helps preserve signal integrity in outdoor burial applications, and the direct burial aspect reduces clutter by eliminating exposed cable runs. This is a fit for smaller installations or where budget-conscious options are required.
CatBose 100FT Outdoor Cat6 Ethernet Cable
CatBose’s 100-foot outdoor Cat6 direct burial cable is designed for robust network installations. With 24 AWG copper-clad aluminum conductors, it supports up to 10 Gbps and 550 MHz, making it suitable for high-speed data transmission in buried or in-ground setups. The UV-protected jacket and waterproofing ensure resilience against sun, moisture, and soil conditions, ideal for outdoor LAN and point-to-point networking in residential or commercial contexts.
UbiGear 300′ Oxygen-Free Copper CAT6 Outdoor Cable
UbiGear offers a 300-foot outdoor CAT6 patch cable designed for direct burial with waterproof, UV-resistant features. The product uses pure oxygen-free copper with 24 AWG conductors, delivering reliable high-speed data transmission suitable for home or office networks. Its heavy-duty construction supports long underground runs, reducing the need for repeated splices or new wiring projects.
Syston Direct Burial Cat 6A+ Ethernet Cable
Though primarily marketed for outdoor data networking, Syston’s Cat 6A+ cable emphasizes outdoor robustness with a direct burial design and a dual-layer jacket for moisture resistance. A 700 MHz bandwidth supports high-speed data transfer suitable for long outdoor links, and its OSP rating aligns with installations where the cable may be buried without protective conduit, offering a strong option for mixed-use outdoor networks in harsh environments.
TRUE CABLE Cat6 Direct Burial Outdoor Cable
TRUE CABLE’s direct burial Cat6 cable is shielded F/UTP with a 500-foot length, designed for harsh outdoor environments. It features 23 AWG solid bare copper conductors and a UV-resistant OSP jacket. The cable supports PoE and PoE++, making it a versatile choice for outdoor networks requiring power delivery to endpoints while maintaining high data integrity through shielding against interference.
Buying Guide: Key Purchase Considerations
- Application and compatibility: Match cable type to the intended use (telephone vs. Ethernet) and ensure connector types (RJ11/RJ12 for phones, RJ45 for Ethernet) align with endpoints.
- Direct burial suitability: Look for UV resistance, moisture barriers, and jacket materials designed for underground exposure to prevent moisture ingress and soil damage.
- Conductor material and gauge: For voice lines, 24 AWG is common; for data, 23-24 AWG with copper or copper-clad aluminum impacts signal quality and cost. Bare copper or OFC copper yields better performance in long runs.
- Shielding and interference: Shielded RJ11/RJ12 cables reduce cross-talk and EMI in outdoor settings. Shielding is especially helpful near power lines or metal obstacles.
- Data vs. power capabilities: Cat6 and higher categories support higher data rates and PoE options, beneficial for outdoor network devices but may be overkill for simple phone lines.
- Installation considerations: Plan burial depth, trench width, and whether conduit is required by local code. Direct burial cables simplify installation but require careful routing to avoid physical damage.
- Regulatory and approvals: Verify compliance with UL444, NEC Article 725, and any local electrical codes to ensure safe use in outdoor environments.
- Budget and length: Longer runs increase cost; consider prefabricated spools vs. modular lengths to minimize waste without sacrificing signal integrity.
Direct burial cables provide a durable solution for extending telephone and network services outdoors. By selecting products designed for underground use and considering installation specifics, you can achieve reliable performance with fewer maintenance concerns over time. This guide presents a cross-section of options suitable for various project scales and environments.
