| Manufacturing Environment Standards | ISO 9001:2015; Class 1000 Cleanroom Production | Manufactured under controlled cleanroom conditions to ensure consistent fiber geometry and coating quality |
| Core Raw Material Source | High-purity synthetic SiO₂ preform (OVD/MCVD process) | Optical-grade silica preform produced via Outside Vapor Deposition ensuring low OH⁻ content and minimal impurities |
| Packaging Specification | Reel: 500 m / 1000 m / 2000 m per spool; Spool diameter: 280 mm or 355 mm | Wound on standard plastic or wooden spools with protective wrapping; custom lengths available on request |
| Storage Conditions | Temperature: -20°C to +60°C; Relative Humidity: ≤ 85% RH (non-condensing) | Store in original sealed packaging away from direct sunlight, chemicals, and mechanical stress |
| Valid Shelf Life | ≥ 20 years (under recommended storage conditions) | Dual UV-cured acrylate coating system ensures long-term mechanical and optical stability |
| Application Scenarios | FTTH/FTTB drop cables, in-building LAN, data center horizontal cabling, FTTA, MDU wiring | Optimized for tight-space indoor routing including risers, plenum spaces, and patch panel installations |
| Compliance & Certification | IEC 60793-2-50; ITU-T G.657.A2; RoHS 2011/65/EU; REACH compliant; UL Listed (optional) | Meets international optical fiber standards and environmental compliance requirements for global market access |
| Minimum Order Quantity (MOQ) | 10 km per order | Flexible MOQ policy available for qualified distributors and project-based procurement |
| Monthly Supply Capacity | 500,000 km/month | Large-scale production capacity with stable supply chain to support major indoor network deployment projects |
Initial Labeling Issue Resolved Quickly by Support Team
Ordered 4,000 meters of G.657A2 single-mode 2-fiber duplex indoor cable for a university campus retrofit in Leeds. Upon arrival, approximately 15% of reels had fiber count labels mismatched with packing list, which caused initial inventory confusion. Raised the issue with support and received corrected documentation and replacement labels within 48 hours. Cable optical performance itself — attenuation 0.20 dB/km at 1550 nm, bend radius compliance — was fully on spec. Problem was resolved professionally, so we would order again cautiously.
