Direct Burial Outdoor Fiber Cable Supplier & Factory
Direct burial outdoor fiber cable stands as one of the most essential infrastructure components in modern telecommunications, enabling reliable underground connectivity across municipal networks, campus backbones, utility corridors, and long-haul broadband deployments. Engineered specifically for direct-in-ground installation without the need for conduit, this rugged outdoor fiber solution delivers exceptional performance in the harshest soil and environmental conditions. As global demand for high-speed broadband, smart city infrastructure, and fiber-to-the-home (FTTH) networks continues to accelerate, direct burial outdoor fiber has become the preferred choice for network engineers and contractors seeking cost-effective, durable, and low-maintenance underground cabling. Our factory supplies premium-grade direct burial fiber cables to telecom operators, ISPs, government agencies, and EPC contractors worldwide, combining advanced manufacturing capabilities with strict quality control to ensure every reel meets international performance benchmarks.
What is Direct Burial Outdoor Fiber?
Direct burial outdoor fiber cable is a specialized underground optical fiber cable designed to be installed directly into soil, sand, or trench environments without requiring protective conduit. It features armored construction — typically with corrugated steel tape (CST) or gel-filled loose tube designs — that provides mechanical crush resistance, moisture protection, and rodent deterrence. Compliant with ITU-T G.652D and G.657A standards, these cables are built to withstand UV exposure, temperature extremes, and soil movement over decades of service life.
Direct Burial Outdoor Fiber Manufacturing and Production Process
Our direct burial outdoor fiber cables are manufactured in ISO 9001-certified production facilities equipped with precision fiber drawing towers, SZ stranding lines, and automated gel-filling systems. The production process begins with ITU-T compliant single-mode or multimode fiber, followed by loose tube formation, water-blocking gel injection, corrugated steel armor application, and UV-resistant polyethylene (PE) jacket extrusion. Each production batch undergoes 100% attenuation testing, tensile load verification, and crush resistance inspection prior to shipment, ensuring full RoHS and IEC 60794 compliance.
Direct Burial Outdoor Fiber Technical Specifications
Our direct burial outdoor fiber cables are available in configurations from 2 to 288 fiber counts, supporting single-mode (G.652D, G.657A1/A2) and OM3/OM4 multimode options. Key parameters include: attenuation ≤0.20 dB/km at 1550 nm, tensile strength up to 2,700 N, crush resistance ≥3,000 N/100 mm, operating temperature range −40°C to +70°C, minimum bend radius 20× cable diameter, and standard PE jacket thickness of 2.0–3.5 mm. Cable outer diameters range from 10 mm to 22 mm depending on fiber count and armor configuration.
