| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Erbium Doped Specialty Fiber | Active rare-earth doped optical fiber with Er³⁺ ions for signal amplification |
| Fiber Grade & ITU-T Classification | Active Specialty Fiber / IEC 60793-2-50 | Compliant with IEC 60793-2-50 Type B active fiber standards for EDFA applications |
| Core & Cladding Diameter Range | Core: 2.0–6.0 μm / Cladding: 125 ± 1.0 μm | Small core diameter enhances Er³⁺ ion interaction with pump and signal light |
| Attenuation Coefficient at 1310 nm | ≤ 5.0 dB/m | Higher background loss acceptable due to short active fiber lengths in amplifiers |
| Attenuation Coefficient at 1550 nm | ≤ 3.0 dB/m (unpumped) | Measured in unpumped state; net gain achieved under 980 nm or 1480 nm pumping |
| Macrobending Loss Performance | ≤ 0.5 dB/turn at R = 15 mm (1550 nm) | Low macrobend sensitivity ensures stable performance in compact coil configurations |
| Chromatic Dispersion Coefficient | 15–20 ps/(nm·km) at 1550 nm | Dispersion managed to minimize pulse broadening in amplified transmission systems |
| Erbium Ion Concentration | 100–3000 ppm (wt) | Concentration tuned to optimize gain per unit length and reduce ASE noise |
| Batch Qualification Rate | ≥ 99.2% | Each production batch undergoes full spectroscopic and optical parameter verification |
| Manufacturing Environment Standards | ISO Class 7 (ISO 14644-1) Cleanroom | MCVD or OVD process in controlled cleanroom to prevent dopant contamination |
| Core Raw Material Source | High-purity SiO₂ + Er₂O₃ / Al₂O₃ co-dopant | Al₂O₃ co-doping broadens gain bandwidth and reduces Er³⁺ ion clustering |
| Packaging Specification | Spool: 5 m / 10 m / 50 m / 100 m per reel | Wound on plastic or aluminum spools with end-cap protection; vacuum-sealed packaging |
| Storage Conditions | Temperature: 0–40 °C / Humidity: ≤ 60% RH | Store away from UV exposure and mechanical stress to preserve coating integrity |
| Valid Shelf Life | 24 months from production date | Optical and gain properties guaranteed within specification for 24-month storage period |
| Application Scenarios | EDFA, fiber lasers, optical sensing, LIDAR | Widely used in C-band/L-band amplifiers, pulsed fiber lasers, and distributed sensing |
| Compliance & Certification | IEC 60793-2-50, RoHS 2011/65/EU, REACH | Meets international optical fiber and hazardous substance compliance requirements |
| Minimum Order Quantity (MOQ) | 50 m | Flexible MOQ available for R&D prototyping and volume production orders |
| Monthly Supply Capacity | 50,000 m/month | Scalable production capacity to support OEM amplifier and laser module manufacturers |
Initial delivery delay caused project disruption — issue since resolved
We procured 1 km of erbium-doped fiber (Er³⁺ ~1200 ppm, core diameter 3.8 µm) for a regional telecom amplifier station upgrade. The fiber specifications — including 980 nm pump absorption at 6.5 dB/m and PMD below 0.1 ps/√km — were fully met and verified against IEC 60793 on arrival. However, DDP delivery to Dubai was delayed by 8 days beyond the committed window due to export documentation issues, which pushed our installation schedule. After escalation, the logistics team resolved the customs paperwork and provided expedited shipping compensation. Product quality was not in question; process execution needs tightening.
