|---|---|---|
| Optical Fiber Product Name | Telecom Low Loss Fiber | Single-mode optical fiber engineered for ultra-low attenuation in long-haul and metro telecom networks |
| Fiber Grade & ITU-T Classification | G.652.D / G.654.E | Compliant with ITU-T G.652.D standard single-mode fiber; G.654.E available for ultra-low loss submarine/terrestrial applications |
| Core & Cladding Diameter Range | Core: 8.2 ± 0.4 µm; Cladding: 125.0 ± 0.7 µm | Tight dimensional tolerances ensure low splice loss and compatibility with standard connectors |
| Attenuation Coefficient at 1310 nm | ≤ 0.34 dB/km | Measured per IEC 60793-1-40; suitable for O-band transmission systems |
| Attenuation Coefficient at 1550 nm | ≤ 0.18 dB/km (standard); ≤ 0.16 dB/km (ultra-low loss grade) | Optimized for C-band and L-band DWDM long-haul transmission |
| Macrobending Loss Performance | ≤ 0.10 dB at R=30 mm (100 turns, 1550 nm) | Tested per IEC 60793-1-47; ensures stable performance in cable routing and deployment |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm; 0 ± 0.5 ps/(nm·km) at 1310 nm | Low dispersion at 1310 nm zero-dispersion wavelength; supports high-speed coherent transmission |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% OTDR screening and geometric parameter verification |
| Manufacturing Environment Standards | ISO Class 5 (Class 100) Cleanroom; MCVD / OVD / VAD Process | Controlled deposition environment minimizes OH⁻ ion contamination and ensures consistent refractive index profile |
| Core Raw Material Source | High-purity SiO₂ preform (≥ 99.999% purity); GeO₂ dopant for core index control | Sourced from certified preform suppliers; low transition metal impurity content (< 1 ppb) |
| Packaging Specification | Standard reel: 2 km, 4 km, 6 km, 12 km per spool; wooden drum or plastic bobbin | Vacuum-sealed with desiccant; labeled with fiber length, attenuation data, and batch traceability code |
| Storage Conditions | Temperature: -40°C to +70°C; Relative Humidity: ≤ 85% RH (non-condensing) | Store in original sealed packaging away from direct sunlight, chemicals, and mechanical stress |
| Valid Shelf Life | ≥ 25 years (under recommended storage conditions) | Coating integrity and optical performance guaranteed within shelf life per IEC 60793-2-50 |
| Application Scenarios | Long-haul backbone, metro DWDM, 5G fronthaul/backhaul, submarine cable, data center interconnect (DCI) | Optimized for high-capacity coherent transmission systems operating at 100G / 400G / 800G per channel |
| Compliance & Certification | ITU-T G.652.D / G.654.E; IEC 60793-2-50; TIA-492CAAB; RoHS 2.0; CE | Third-party test reports available; compliant with international telecom operator procurement standards |
| Minimum Order Quantity (MOQ) | 500 km per order | Custom reel lengths and packaging configurations available for orders ≥ 2,000 km |
| Monthly Supply Capacity | 50,000 km / month | Scalable to 80,000 km/month with advance scheduling; supports large-scale network rollout projects |
Fiber quality is good, but initial customs documentation needed correction
Ordered 200 km of G.652D fiber for a 5G backhaul project. The fiber itself tested well—attenuation at 1550 nm measured 0.18 dB/km and cladding geometry was within spec. However, the initial commercial invoice had an incorrect HS code, which caused a two-day customs hold in Dubai. After contacting the support team, corrected documentation was issued within 12 hours and clearance proceeded without further issues. The supplier acknowledged the error and confirmed an updated documentation checklist for UAE shipments. Fiber performance is not in question; process improvement is ongoing.
