| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Fiber Optic Single-Mode Cable | Single-mode optical fiber cable designed for long-distance, high-bandwidth data transmission |
| Fiber Grade & ITU-T Classification | ITU-T G.652D / G.657A1 | Standard single-mode fiber compliant with ITU-T G.652D; bend-insensitive variant meets G.657A1 |
| Core & Cladding Diameter Range | Core: 8.2 μm / Cladding: 125 ± 0.7 μm | Tight tolerance on cladding diameter ensures low splice loss and consistent optical performance |
| Attenuation Coefficient at 1310 nm | ≤ 0.34 dB/km | Measured per IEC 60793-1-40; suitable for metropolitan and access network deployment |
| Attenuation Coefficient at 1550 nm | ≤ 0.20 dB/km | Ultra-low loss at 1550 nm window; optimized for long-haul DWDM transmission systems |
| Macrobending Loss Performance | ≤ 0.10 dB at R = 30 mm (100 turns, 1550 nm) | Tested per IEC 60793-1-47; G.657A1 variant achieves ≤ 0.50 dB at R = 10 mm |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm | Zero-dispersion wavelength range: 1300–1324 nm; dispersion slope ≤ 0.092 ps/(nm²·km) |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% OTDR screening and tensile proof testing at 1% strain |
| Manufacturing Environment Standards | ISO 9001:2015 / ISO 14001:2015 | Produced in dust-controlled cleanroom environment; full traceability from preform to finished cable |
| Core Raw Material Source | High-purity synthetic silica (SiO₂ ≥ 99.99%) | MCVD/OVD/PCVD process; dopant-controlled refractive index profile for precise mode-field diameter |
| Packaging Specification | Wooden drum / plastic reel; 1 km, 2 km, 4 km, 6 km per reel | Drum labeled with fiber length, attenuation test data, and batch number; moisture-proof wrapping included |
| Storage Conditions | Temperature: -20°C to +60°C; Humidity: 10%–85% RH (non-condensing) | Store on original reel in dry, shaded environment; avoid direct UV exposure and mechanical compression |
| Valid Shelf Life | 25 years (installed); 2 years (uninstalled, sealed packaging) | Optical performance guaranteed within shelf life when stored per specified conditions |
| Application Scenarios | FTTH/FTTB, long-haul backbone, DWDM networks, data center interconnect, 5G fronthaul/backhaul | Compatible with SC, LC, FC, ST connectors; supports 10G/40G/100G/400G transmission protocols |
| Compliance & Certification | IEC 60794-1, ITU-T G.652D, RoHS 2011/65/EU, UL Listed (OFNR/OFNP) | CE marked; optional LSZH jacket available for indoor plenum and riser installations |
| Minimum Order Quantity (MOQ) | 10 km | Custom reel lengths and jacket colors available for orders ≥ 50 km; OEM labeling supported |
| Monthly Supply Capacity | 500,000 km/month | Supported by automated draw tower production lines; lead time 7–15 business days for standard orders |
Initial Batch Had Coating Inconsistency — Issue Resolved with Replacement Shipment
Our first order of 40,000 meters of OS2 armored SMF cable showed UV-cured acrylate coating irregularities on approximately 8% of sampled fiber lengths, flagged during incoming QC against our ITU-T G.652D acceptance criteria. We raised this immediately with their technical team, who responded within 4 hours, reviewed our OTDR and visual inspection data, and arranged a replacement shipment for the affected reels within 10 days at no cost. The replacement batch passed all tests. The issue resolution was handled professionally, but the initial QC miss was a concern. Subsequent orders have been clean.
