| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | 850nm Multimode Fiber Optic Cable for Short Haul | Multimode optical fiber cable optimized for 850nm wavelength transmission in short-distance applications |
| Fiber Grade & ITU-T Classification | OM3 / OM4 (ITU-T G.651.1) | 50/125μm laser-optimized multimode fiber compliant with ITU-T G.651.1 standard |
| Core & Cladding Diameter Range | Core: 50μm ±2.5μm; Cladding: 125μm ±1μm | Tight dimensional tolerance ensures consistent coupling efficiency and low splice loss |
| Attenuation Coefficient at 850nm | ≤2.3 dB/km (OM3); ≤2.0 dB/km (OM4) | Primary operating wavelength for VCSEL-based short haul data center links |
| Attenuation Coefficient at 1310nm | ≤0.4 dB/km | Secondary wavelength attenuation for dual-window multimode operation |
| Attenuation Coefficient at 1550nm | ≤0.3 dB/km | Reference attenuation at 1550nm for extended wavelength compatibility verification |
| Macrobending Loss Performance | ≤0.5 dB at R=15mm, 100 turns, 850nm | Low macrobend sensitivity suitable for tight routing in data center cable trays |
| Chromatic Dispersion Coefficient | ≤3.5 ps/(nm·km) at 850nm | Minimal chromatic dispersion supports high-bandwidth multimode transmission |
| Effective Modal Bandwidth (EMB) | OM3: ≥2000 MHz·km; OM4: ≥4700 MHz·km at 850nm | High EMB enables 10G/40G/100G Ethernet over distances up to 300m (OM3) and 550m (OM4) |
| Batch Qualification Rate | ≥99.5% | Each production batch undergoes 100% OTDR and attenuation testing before shipment |
| Manufacturing Environment Standards | ISO 9001:2015; IEC 60793-2-10 | Produced in dust-controlled cleanroom environment meeting IEC fiber geometry standards |
| Core Raw Material Source | High-purity silica glass (SiO₂ ≥99.99%) | Germanium-doped silica core with fluorine-doped silica cladding for precise refractive index profile |
| Packaging Specification | 500m, 1000m, 2000m per reel; wooden or plastic drum | Standard reel packaging with moisture-proof wrapping; custom lengths available on request |
| Storage Conditions | Temperature: -20°C to +60°C; Humidity: 10%–85% RH (non-condensing) | Store in original packaging away from direct sunlight and corrosive chemicals |
| Valid Shelf Life | 25 years under recommended storage conditions | Fiber coating and optical performance guaranteed for 25 years per IEC 60793-1-32 |
| Application Scenarios | Data center interconnects, LAN backbone, SAN, 10G/40G/100G Ethernet, short haul ≤550m | Ideal for high-density server-to-switch links and intra-building fiber backbone installations |
| Compliance & Certification | IEC 60793-2-10, TIA-492AAAC (OM3), TIA-492AAAD (OM4), RoHS 2011/65/EU | Fully compliant with international multimode fiber standards and EU environmental directives |
| Minimum Order Quantity (MOQ) | 1 reel (500m) | Single-reel orders accepted; volume pricing available for orders ≥50 reels |
| Monthly Supply Capacity | 500,000 meters/month | Stable production capacity supports large-scale data center and telecom infrastructure projects |
Initial lead time issue resolved — product quality is good
We ordered 2,500 meters of OM3 50µm LSZH cable for a Dubai free zone office campus project. Initial delivery was delayed by 8 days beyond the confirmed lead time, which created scheduling pressure on our installation team. After raising the issue, the supplier's logistics team communicated proactively and expedited the remaining shipment. The cable itself tested correctly — attenuation ≤2.3 dB/km at 850nm and ITU-T G.651.1 compliant per batch test reports. The problem was acknowledged and resolved. We are willing to try again with a clear lead time commitment.
