| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Ultra Low Loss Fiber | Single-mode optical fiber engineered for minimal signal attenuation over long-distance transmission |
| Fiber Grade & ITU-T Classification | ITU-T G.654.E / G.652.D | Compliant with ITU-T G.654.E for ultra-low loss and large effective area applications |
| Core & Cladding Diameter Range | Core: 9.0–13.0 μm / Cladding: 125.0 ± 0.7 μm | Precisely controlled geometry ensuring consistent mode field and low splice loss |
| Attenuation Coefficient at 1310 nm | ≤ 0.32 dB/km | Measured per IEC 60793-1-40; suitable for metro and regional network deployment |
| Attenuation Coefficient at 1550 nm | ≤ 0.16 dB/km | Industry-leading low attenuation enabling ultra-long-haul transmission without amplification |
| Macrobending Loss Performance | ≤ 0.10 dB at R=30 mm (100 turns, 1550 nm) | Tested per IEC 60793-1-47; excellent bend resistance for cable installation environments |
| Chromatic Dispersion Coefficient | ≤ 20 ps/(nm·km) at 1550 nm | Low dispersion supports high-speed coherent transmission systems up to 400G and beyond |
| Batch Qualification Rate | ≥ 99.5% | Strict in-line quality control ensures consistent performance across production batches |
| Manufacturing Environment Standards | ISO Class 5 (Class 100) Cleanroom | Controlled cleanroom environment minimizes contamination during preform and draw processes |
| Core Raw Material Source | High-purity synthetic SiO₂ (OH⁻ ≤ 0.1 ppb) | Ultra-pure silica preform with extremely low hydroxyl content to reduce water-peak attenuation |
| Packaging Specification | Wooden reel: 2.0 km / 4.0 km / 6.25 km per reel | Standard IEC wooden reels with protective wrapping; custom reel lengths available on request |
| Storage Conditions | Temperature: -40°C to +70°C; Humidity: ≤ 85% RH (non-condensing) | Store in original packaging away from direct sunlight and corrosive chemicals |
| Valid Shelf Life | ≥ 5 years under recommended storage conditions | Fiber optical performance remains stable within ITU-T specification throughout shelf life |
| Application Scenarios | Submarine cable systems, transoceanic links, long-haul DWDM, 5G backbone networks | Optimized for high-capacity coherent optical transmission requiring minimum signal loss |
| Compliance & Certification | ITU-T G.654.E, IEC 60793-2-50, RoHS 2011/65/EU, REACH | Fully certified for international telecommunications infrastructure projects |
| Minimum Order Quantity (MOQ) | 50 km per order | MOQ applies per fiber type; mixed reel configurations accepted above MOQ threshold |
| Monthly Supply Capacity | ≥ 500,000 km/month | Large-scale production capacity supports global submarine and terrestrial cable projects |
Initial batch had labeling inconsistency — issue fully resolved
Our first order of 300 km of G.654.E fiber arrived with reel labeling that didn't match the attenuation values on the accompanying test certificates — a compliance concern for our project documentation. We flagged this immediately. The supplier's quality team responded within 12 hours, issued corrected certificates with reel-matched attenuation data (all verified ≤0.17 dB/km at 1550 nm), and updated their labeling process. The fiber itself performed correctly in the field. The issue was administrative, not technical, and was resolved fully within 48 hours. Upgrading our rating once we complete the second order evaluation.
