| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Building Indoor Optical Fiber | Single-mode/multimode optical fiber designed for indoor building wiring and distribution networks |
| Fiber Grade & ITU-T Classification | G.652D / G.657A1 / G.657A2 / OM3 / OM4 | Compliant with ITU-T G.652D for standard SMF, G.657A1/A2 for bend-insensitive SMF, OM3/OM4 for multimode |
| Core & Cladding Diameter Range | Core: 8.2 μm (SMF) / 50 μm (MMF); Cladding: 125.0 ± 0.7 μm | Tight tolerance on cladding diameter ensures low splice loss and reliable connector performance |
| Attenuation Coefficient at 1310nm | ≤ 0.34 dB/km (SMF); ≤ 3.5 dB/km (MMF) | Low attenuation at 1310 nm supports long-distance intra-building signal transmission |
| Attenuation Coefficient at 1550nm | ≤ 0.20 dB/km (SMF); ≤ 1.5 dB/km (MMF) | Ultra-low attenuation at 1550 nm suitable for FTTH and high-density indoor deployments |
| Macrobending Loss Performance | G.657A2: ≤ 0.03 dB/turn @ R=7.5 mm, 1550 nm | Excellent bend resistance allows tight routing in conduits, cable trays, and wall outlets |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) @ 1550 nm; Zero-dispersion wavelength: 1300–1324 nm | Low chromatic dispersion ensures signal integrity for high-speed indoor data transmission |
| Batch Qualification Rate | ≥ 99.5% | Strict process control ensures consistent optical and mechanical performance across production batches |
| Manufacturing Environment Standards | ISO Class 7 (ISO 14644-1) Cleanroom; Temperature: 20 ± 2 °C; Humidity: 45–65% RH | Controlled cleanroom environment prevents contamination and ensures coating uniformity |
| Core Raw Material Source | High-purity SiO₂ preform (OVD/MCVD/PCVD process); Acrylate dual-layer UV-cured coating | Premium silica preform with low OH content; dual-layer coating provides mechanical protection |
| Packaging Specification | Spool: 1 km / 2 km / 5 km per reel; Reel diameter: 280–400 mm | Standard plastic or wooden reels with moisture-proof packaging; custom lengths available on request |
| Storage Conditions | Temperature: -20 °C to +60 °C; Humidity: ≤ 85% RH (non-condensing); Avoid direct UV exposure | |
| Valid Shelf Life | ≥ 25 years (installed); 2 years (sealed original packaging) | Long service life under normal indoor environmental conditions per IEC 60793-2 guidelines |
| Application Scenarios | FTTH/FTTB drop cables, horizontal cabling, riser cables, patch cord cores, MDU/office building LAN | Optimized for tight-space indoor routing in residential buildings, offices, data centers, and hotels |
| Compliance & Certification | ITU-T G.652D / G.657A1 / G.657A2; IEC 60793-2-50; TIA-568-C.3; RoHS 2011/65/EU; REACH | Internationally recognized certifications ensure compatibility with global indoor cabling standards |
| Minimum Order Quantity (MOQ) | 10 km (single fiber type); 50 km (mixed specifications) | Flexible MOQ policy available for project-based procurement and system integrators |
| Monthly Supply Capacity | ≥ 500,000 km/month | Large-scale production capacity supports national and international bulk indoor fiber deployment projects |
Solid Product After Initial Shipment Discrepancy — Issue Resolved
Ordered 72-core LSZH tight-buffered indoor fiber for a multi-dwelling unit project in Melbourne. Initial shipment included 8 reels with fiber count labeling that didn't match our purchase order — caused a brief installation delay. Raised the issue immediately; supplier responded within 4 hours, provided correct replacement reels via expedited freight at no additional cost, and issued a formal corrective action report. Optical attenuation and IEC 60332-1 flame test results on all final cables were fully compliant. The after-sales response was genuinely professional and the cable quality itself is good. Cautiously optimistic for future orders.
