| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Direct Burial Outdoor Fiber | Armored outdoor fiber optic cable designed for direct underground burial without conduit |
| Fiber Grade & ITU-T Classification | ITU-T G.652D / G.657A1 | Single-mode OS2 grade fiber, compliant with ITU-T G.652D standard for low water peak performance |
| Core & Cladding Diameter Range | Core: 9 µm / Cladding: 125 ± 0.7 µm | Standard single-mode core with tight cladding tolerance for consistent splice and connector performance |
| Attenuation Coefficient at 1310nm | ≤ 0.35 dB/km | Maximum attenuation at 1310 nm wavelength under standard test conditions per IEC 60793-1-40 |
| Attenuation Coefficient at 1550nm | ≤ 0.20 dB/km | Maximum attenuation at 1550 nm wavelength, optimized for long-haul and DWDM transmission |
| Macrobending Loss Performance | ≤ 0.10 dB at R=30 mm (100 turns, 1550 nm) | Low macrobend sensitivity suitable for installation in tight routing paths and burial environments |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm | Dispersion value within ITU-T G.652D limits, supporting high-speed data transmission up to 10 Gbps |
| Batch Qualification Rate | ≥ 99.5% | Per-batch optical and mechanical parameter pass rate verified by full-reel OTDR and tensile testing |
| Manufacturing Environment Standards | ISO 9001:2015 / IEC 60794-1 | Produced in dust-controlled facilities meeting ISO cleanroom requirements and IEC cable construction standards |
| Core Raw Material Source | High-purity SiO₂ preform (OVD/MCVD process) | Optical-grade silica preform sourced from certified suppliers; free from OH-ion contamination |
| Packaging Specification | Wooden drum / 1000 m, 2000 m, 4000 m per reel | Moisture-resistant wooden drums with sealed end caps; reel dimensions labeled per IEC 60794-1-1 |
| Storage Conditions | Temperature: -20°C to +60°C; Humidity: ≤ 85% RH | Store in dry, shaded warehouse away from direct sunlight, chemicals, and mechanical stress |
| Valid Shelf Life | 25 years (installed) / 2 years (uninstalled, sealed) | Designed service life of 25 years when buried per installation guidelines; 2-year shelf life on sealed reels |
| Application Scenarios | Direct underground burial, campus networks, rural broadband, utility corridors | Suitable for FTTx, municipal infrastructure, oil & gas field networks, and inter-building backbone links |
| Compliance & Certification | ITU-T G.652D, IEC 60794-1, RoHS 2011/65/EU, UL Listed | Fully compliant with international fiber and cable standards; RoHS-compliant jacket materials |
| Minimum Order Quantity (MOQ) | 2,000 m (1 reel) | Minimum purchase of one standard reel; custom reel lengths available for orders ≥ 10,000 m |
| Monthly Supply Capacity | 500,000 m / month | Standard production capacity; surge capacity up to 800,000 m/month with 30-day advance scheduling |
Initial reel labeling mismatch — resolved quickly, cable performance is fine
We ordered 36-fiber and 72-fiber G.652D reels for a mixed rural/suburban deployment in Ohio. On arrival, two reels were labeled with incorrect fiber counts — 36F labels on 72F reels. This caused a scheduling delay on site. After contacting the sales engineer, corrected documentation and replacement labels arrived digitally within 6 hours and physically within 3 days. The actual cable performance was not affected: attenuation measured 0.19 dB/km at 1550 nm and tensile strength verified at 2,650 N. Issue was administrative, not a product defect. Happy to order again with this clarified.
