| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Short Distance Multi-Mode Fiber | Multimode optical fiber optimized for short-reach data transmission in LAN, data center, and campus network environments |
| Fiber Grade & ITU-T Classification | OM3 / OM4 / OM5 (IEC 60793-2-10) | Compliant with ITU-T G.651.1; OM3/OM4 for 10G–100G, OM5 for SWDM wideband applications |
| Core & Cladding Diameter Range | Core: 50 µm or 62.5 µm; Cladding: 125 µm ± 1 µm | Standard 50/125 µm preferred for high-bandwidth short-distance links; 62.5/125 µm for legacy systems |
| Attenuation Coefficient at 850 nm | ≤ 2.3 dB/km (OM3/OM4); ≤ 2.5 dB/km (62.5 µm) | Primary operating wavelength for VCSEL-based multimode transceivers |
| Attenuation Coefficient at 1310 nm | ≤ 0.6 dB/km | Secondary wavelength; lower attenuation supports extended short-distance links |
| Attenuation Coefficient at 1550 nm | ≤ 0.4 dB/km | Reference parameter; not primary for multimode but verified for full-spectrum quality assurance |
| Macrobending Loss Performance | ≤ 0.5 dB at R = 15 mm (100 turns, 850 nm) | Meets IEC 60793-1-47 bend test; suitable for tight-routing installations in cabinets and trays |
| Chromatic Dispersion Coefficient | Zero-dispersion wavelength: 850 nm ± 30 nm; Dispersion slope ≤ 0.11 ps/(nm²·km) | Optimized for 850 nm VCSEL sources; modal bandwidth dominates over chromatic dispersion at short distances |
| Modal Bandwidth (Overfilled Launch) | OM3: ≥ 1500 MHz·km; OM4: ≥ 3500 MHz·km at 850 nm | Effective Modal Bandwidth (EMB): OM3 ≥ 2000 MHz·km; OM4 ≥ 4700 MHz·km for laser-optimized performance |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% end-face geometry, attenuation, and bandwidth screening before shipment |
| Manufacturing Environment Standards | ISO Class 7 (ISO 14644-1) cleanroom; temperature 23 ± 2 °C; humidity 45%–55% RH | Controlled drawing and coating environment ensures consistent optical and mechanical performance |
| Core Raw Material Source | High-purity silica preform (SiO₂ purity ≥ 99.999%); MCVD / OVD / VAD process | Graded-index germanium-doped silica core; fluorine-doped silica cladding for precise refractive index profile |
| Packaging Specification | Standard reel: 500 m, 1000 m, 2000 m, 5000 m per spool; custom lengths available | Wooden or plastic bobbin with moisture-proof PE film wrapping; labeled with fiber type, length, and lot number |
| Storage Conditions | Temperature: -20 °C to +60 °C; Relative Humidity: ≤ 85% RH (non-condensing) | Store away from direct sunlight, corrosive gases, and mechanical stress; keep in original sealed packaging |
| Valid Shelf Life | ≥ 20 years under recommended storage conditions | Coating and optical properties remain stable; periodic inspection recommended for long-term warehouse stock |
| Application Scenarios | Data centers (10G/25G/40G/100G), LAN backbone, campus networks, FTTD, medical imaging, industrial automation | Supports IEEE 802.3 Ethernet standards; link distances up to 300 m (OM3) and 400 m (OM4) at 10G |
| Compliance & Certification | IEC 60793-2-10, IEC 60794-1, TIA-492AAAC (OM3), TIA-492AAAD (OM4), RoHS 2011/65/EU, REACH | Third-party test reports available; UL listing and CE declaration provided upon request |
| Minimum Order Quantity (MOQ) | 5,000 m (single fiber type per order) | Mixed-type orders accepted with combined MOQ ≥ 10,000 m; sample reels (500 m) available for qualification testing |
| Monthly Supply Capacity | ≥ 500,000 m / month | Scalable to 2,000,000 m/month with advance scheduling; OEM and private-label services available |
Initial shipment had a documentation gap — resolved promptly
Ordered 2,500 meters of OM3 50/125 µm fiber for a UK education sector project requiring full IEC 60793-2-10 and RoHS compliance documentation for the client's audit. The first shipment arrived without the batch-specific attenuation test reports. This was a problem as our client required per-batch traceability. I contacted their support team, and the complete test documentation was emailed within 4 hours and a physical copy dispatched same day. Cable performance itself was fine — attenuation at 850 nm was 2.9 dB/km. Issue was resolved efficiently, and I would consider ordering again with the documentation requirement confirmed upfront.
