| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Long Distance Low-Loss Fiber | Single-mode optical fiber engineered for ultra-low attenuation over extended transmission distances |
| Fiber Grade & ITU-T Classification | G.654.E / G.652.D | Compliant with ITU-T G.654.E for ultra-low-loss long-haul applications; G.652.D for standard SMF compatibility |
| Core & Cladding Diameter Range | Core: 9.0–9.5 µm; Cladding: 125.0 ± 0.7 µm | Precision-controlled geometry ensures consistent mode field and low splice loss across fiber lengths |
| Attenuation Coefficient at 1310 nm | ≤ 0.32 dB/km | Measured per IEC 60793-1-40; optimized for O-band transmission in metro and access networks |
| Attenuation Coefficient at 1550 nm | ≤ 0.17 dB/km | Industry-leading low-loss performance at C-band; suitable for transoceanic and terrestrial long-haul links |
| Macrobending Loss Performance | ≤ 0.003 dB/turn at R=30 mm (1550 nm) | Tested per IEC 60793-1-47; excellent bend resistance for cable installation in conduit and tight routing |
| Chromatic Dispersion Coefficient | 17.0 ± 0.5 ps/(nm·km) at 1550 nm | Low dispersion slope minimizes pulse broadening; compatible with coherent DWDM transmission systems |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% OTDR screening and geometry inspection before shipment |
| Manufacturing Environment Standards | ISO Class 5 (ISO 14644-1) Cleanroom | Fiber drawing and coating performed in controlled cleanroom environment to eliminate contamination-induced defects |
| Core Raw Material Source | High-purity synthetic silica (SiO₂ ≥ 99.999%) | Sourced from certified suppliers; ultra-low OH content (< 0.1 ppm) ensures minimal water-peak attenuation |
| Packaging Specification | Wooden reel; 5 km, 10 km, 25 km per reel | Anti-static protective wrapping; reel labeled with fiber length, attenuation data, and batch traceability code |
| Storage Conditions | Temperature: -20°C to +60°C; Humidity: 10%–85% RH (non-condensing) | Store in original packaging away from direct sunlight, corrosive gases, and mechanical stress |
| Valid Shelf Life | 25 years (under recommended storage conditions) | Dual-layer acrylate coating provides long-term mechanical and environmental protection |
| Application Scenarios | Long-haul terrestrial backbone, submarine cable systems, DWDM/coherent 400G+ networks, data center interconnect (DCI) | Ideal for telecom operators, submarine cable projects, and hyperscale data center operators requiring ultra-low-loss links |
| Compliance & Certification | ITU-T G.654.E, ITU-T G.652.D, IEC 60793-2-50, RoHS 2011/65/EU, REACH | Fully certified for international telecom infrastructure deployment; RoHS and REACH compliant for global market access |
| Minimum Order Quantity (MOQ) | 50 km (≥ 5 reels) | Flexible reel configurations available for project-specific requirements; sample reels available upon request |
| Monthly Supply Capacity | 500,000 km/month | Supported by automated drawing towers and in-line quality control systems ensuring consistent large-volume delivery |
Initial reel labeling inconsistency — resolved promptly by supplier
Ordered 300 km of G.652.D fiber for a regional metro ring project. Upon arrival, roughly 8% of reels had mismatched reel ID labels versus the shipping manifest, creating inventory reconciliation issues for our team. I raised the issue with the account manager, who responded within four hours and provided corrected documentation within one business day. Optical specs — including ≤0.17 dB/km at 1550 nm and 125 µm cladding diameter — were fully verified and compliant. The product itself is solid; the labeling process just needs tighter QC. Issue is now resolved.
