| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Wholesale Outdoor Fiber Optic Cable | Heavy-duty outdoor-rated fiber optic cable designed for bulk wholesale supply and large-scale deployment |
| Fiber Grade & ITU-T Classification | ITU-T G.652D / G.657A2 | Standard single-mode fiber (G.652D) and bend-insensitive single-mode fiber (G.657A2) available for outdoor applications |
| Core & Cladding Diameter Range | Core: 9 µm / Cladding: 125 ± 1 µm | Standard single-mode core diameter with tight cladding tolerance for consistent optical performance |
| Attenuation Coefficient at 1310nm | ≤ 0.35 dB/km | Maximum attenuation at 1310 nm wavelength per ITU-T G.652D specification |
| Attenuation Coefficient at 1550nm | ≤ 0.20 dB/km | Maximum attenuation at 1550 nm wavelength, optimized for long-haul outdoor transmission |
| Macrobending Loss Performance | ≤ 0.10 dB at R=30 mm (100 turns, 1550 nm) | Low macrobending loss ensures stable signal integrity during outdoor installation and routing |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm | Chromatic dispersion within ITU-T G.652D limits, supporting high-speed data transmission over outdoor links |
| Batch Qualification Rate | ≥ 99.5% | Per-batch optical and mechanical parameter pass rate verified by in-line quality inspection systems |
| Manufacturing Environment Standards | ISO 9001:2015 / ISO 14001:2015 | Produced in certified clean-room manufacturing facilities with full environmental and quality management compliance |
| Core Raw Material Source | High-purity SiO₂ preform (OVD/MCVD process) | Optical-grade silica preform manufactured via Outside Vapor Deposition or Modified Chemical Vapor Deposition process |
| Packaging Specification | 1 km / 2 km / 4 km per wooden drum; custom lengths available | Standard wooden cable drums with moisture-resistant wrapping; custom drum lengths supported for wholesale orders |
| Storage Conditions | Temperature: -20°C to +60°C; Humidity: ≤ 85% RH | Store in dry, ventilated warehouse away from direct sunlight and corrosive substances |
| Valid Shelf Life | ≥ 25 years (installed); 2 years (stored on drum) | Designed service life of 25+ years under standard outdoor conditions; 2-year shelf life for uninstalled stock |
| Application Scenarios | FTTH/FTTB trunk lines, aerial deployment, direct burial, duct installation, campus networks | Suitable for telecom backbone, ISP last-mile outdoor runs, industrial parks, and municipal infrastructure projects |
| Compliance & Certification | ITU-T G.652D, IEC 60794-1, RoHS, CE, TIA-568 | Fully compliant with international optical fiber and cable standards; RoHS-certified for hazardous substance restriction |
| Minimum Order Quantity (MOQ) | 10 km per fiber type | Minimum wholesale order of 10 km per fiber specification; mixed-type orders accepted with combined MOQ |
| Monthly Supply Capacity | ≥ 500,000 km/month | Large-scale production capacity supporting global wholesale distributors, telecom operators, and EPC contractors |
Initial Delivery Delay Resolved — Product Quality Acceptable
Our order of 12-core G.657A aerial cable for a rural broadband project in Wales arrived 11 days later than the original schedule due to a port congestion issue. This caused a minor site delay. However, the supplier's logistics team communicated proactively throughout and provided revised ETAs daily. Once received, the cable met all specified parameters — attenuation at 0.20 dB/km at 1550 nm, bend radius performance per G.657A standard confirmed. RoHS compliance certificate was in order. The delay issue appears to have been a one-off. Willing to order again with a buffer timeline built in.
