| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Low-Loss Fiber Optic Cable | Single-mode low-attenuation optical fiber cable designed for long-haul and high-density transmission networks |
| Fiber Grade & ITU-T Classification | G.652D / G.654E / G.657A1 | Compliant with ITU-T G.652D standard for standard SMF; G.654E for ultra-low-loss; G.657A1 for bend-insensitive variants |
| Core & Cladding Diameter Range | Core: 8.2 ± 0.4 μm; Cladding: 125.0 ± 0.7 μm | Tight dimensional tolerance ensures consistent splice loss and connector performance across production batches |
| Attenuation Coefficient at 1310 nm | ≤ 0.34 dB/km | Measured per IEC 60793-1-40; suitable for metro and access network deployment at O-band wavelength |
| Attenuation Coefficient at 1550 nm | ≤ 0.18 dB/km (standard); ≤ 0.16 dB/km (ultra-low-loss) | Measured per IEC 60793-1-40; ultra-low-loss grade supports transoceanic and long-haul DWDM applications |
| Macrobending Loss Performance | ≤ 0.10 dB at R = 30 mm (100 turns, 1550 nm) | Tested per IEC 60793-1-47; bend-insensitive variants achieve ≤ 0.03 dB at R = 15 mm for FTTH deployment |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm; ≤ 3.5 ps/(nm·km) at 1310 nm | Zero-dispersion wavelength: 1300–1324 nm; dispersion slope ≤ 0.092 ps/(nm²·km) per ITU-T G.652D |
| Batch Qualification Rate | ≥ 99.5% | Each production reel undergoes 100% OTDR screening and attenuation verification before shipment approval |
| Manufacturing Environment Standards | ISO 9001:2015; ISO 14001:2015; Class 1000 cleanroom fiber drawing | Fiber preform fabrication and drawing performed in temperature- and humidity-controlled cleanroom environments |
| Core Raw Material Source | High-purity synthetic silica (SiO₂ purity ≥ 99.999%) | Preform manufactured via MCVD / OVD / PCVD process; dopant-free core for ultra-low Rayleigh scattering loss |
| Packaging Specification | Wooden drum / plastic reel; standard lengths: 2 km, 4 km, 6 km per reel | Reels labeled with fiber type, length, attenuation test data, and batch number; moisture-proof wrapping included |
| Storage Conditions | Temperature: -20 °C to +60 °C; Relative Humidity: 5%–95% (non-condensing) | Store in dry, ventilated warehouse away from direct sunlight, corrosive gases, and mechanical stress |
| Valid Shelf Life | 25 years (installed); 2 years (uninstalled, sealed packaging) | Shelf life based on UV-resistant coating integrity and mechanical strength retention under standard storage conditions |
| Application Scenarios | FTTH/FTTB, DWDM long-haul backbone, 5G fronthaul/midhaul, data center interconnect, submarine cable feeder | Optimized for high-bandwidth, low-latency transmission in both aerial, direct-burial, and indoor conduit installations |
| Compliance & Certification | IEC 60793-2-50; ITU-T G.652D / G.654E; RoHS 2011/65/EU; UL Listed (OFNR/OFNP) | Third-party certified by TÜV Rheinland / SGS; CE marking available; REACH compliance documentation provided |
| Minimum Order Quantity (MOQ) | 10 km (≈ 2–5 reels depending on reel length) | Sample orders of 1–2 km available for qualification testing; OEM/ODM custom jacket color and labeling accepted |
| Monthly Supply Capacity | 500,000 km / month | Supported by automated fiber drawing towers with real-time diameter and coating thickness monitoring systems |
Initial reel labeling issue — resolved promptly, cable performance is fine
Ordered 15,000 meters of G.652D single-mode for a metropolitan ring project. On arrival, three of the 20 reels had mislabeled length markings — a 500 m discrepancy per reel — which created scheduling complications on site. I raised this immediately and the supplier dispatched replacement reels via express air freight within five business days at no additional cost, plus issued a credit note for the delay impact. Actual cable attenuation (≤0.18 dB/km at 1550 nm) and IEC 60793 compliance were verified and correct throughout. Issue was handled professionally once escalated. Cautiously optimistic for future orders.
