| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Gigabit Network Multi-Mode Fiber | High-bandwidth multimode optical fiber designed for gigabit Ethernet and data center interconnects |
| Fiber Grade & ITU-T Classification | OM3 / OM4 (IEC 60793-2-10 Type A1a.3 / A1a.4) | Laser-optimized multimode fiber compliant with ITU-T G.651.1 and ISO/IEC 11801 standards |
| Core & Cladding Diameter Range | Core: 50 μm ± 2.5 μm; Cladding: 125 μm ± 1 μm | Tight dimensional tolerance ensures low splice loss and consistent connector performance |
| Attenuation Coefficient at 850 nm | ≤ 2.3 dB/km (OM3); ≤ 2.0 dB/km (OM4) | Low attenuation at 850 nm VCSEL launch wavelength for short-reach gigabit transmission |
| Attenuation Coefficient at 1300 nm | ≤ 0.6 dB/km | Suitable for dual-window operation supporting legacy LED-based gigabit systems |
| Modal Bandwidth (Overfilled Launch) | ≥ 1500 MHz·km @ 850 nm (OM3); ≥ 3500 MHz·km @ 850 nm (OM4) | High OFL bandwidth enables 10G/40G/100G transmission over extended distances |
| Effective Modal Bandwidth (EMB) | ≥ 2000 MHz·km (OM3); ≥ 4700 MHz·km (OM4) | Laser-optimized EMB ensures reliable performance with 850 nm VCSEL sources |
| Macrobending Loss Performance | ≤ 0.5 dB per 100 turns @ R = 37.5 mm (850 nm) | Excellent bend resistance suitable for tight-routing installations in data centers |
| Chromatic Dispersion Coefficient | ≤ 105 ps/(nm·km) @ 850 nm | Low chromatic dispersion supports high-speed signal integrity over multimode links |
| Numerical Aperture (NA) | 0.200 ± 0.015 | Optimized NA balances light-gathering efficiency and modal noise performance |
| Batch Qualification Rate | ≥ 99.5% | Strict in-process and final inspection ensures consistent batch-to-batch optical performance |
| Manufacturing Environment Standards | ISO 9001:2015; Class 1000 Clean Room Production | Controlled cleanroom environment minimizes contamination during fiber draw and coating |
| Core Raw Material Source | High-purity synthetic silica (SiO₂ purity ≥ 99.99%) | Premium-grade silica preform produced via MCVD/OVD process for uniform refractive index profile |
| Packaging Specification | Wooden reel: 1 km, 2 km, 4 km per reel; customizable lengths available | Anti-static protective wrapping with moisture-proof packaging for safe long-distance shipping |
| Storage Conditions | Temperature: -20°C to +60°C; Relative Humidity: ≤ 85% RH (non-condensing) | Store in dry, ventilated warehouse away from direct sunlight and corrosive substances |
| Valid Shelf Life | ≥ 20 years under recommended storage conditions | Hermetic silica structure ensures long-term mechanical and optical stability |
| Application Scenarios | Data centers, campus networks, gigabit/10G Ethernet, SAN, FTTB backbone | Ideal for 1G/10G/40G/100G short-reach links up to 300 m (OM3) and 550 m (OM4) |
| Compliance & Certification | IEC 60793-2-10, ISO/IEC 11801, TIA-492AAAC/D, RoHS 2011/65/EU | Fully certified for international procurement, telecom infrastructure and green building projects |
| Minimum Order Quantity (MOQ) | 10 km (≈ 5 reels × 2 km) | Flexible MOQ policy available for long-term contract customers and system integrators |
| Monthly Supply Capacity | 500,000 km / month | Large-scale production capacity supports global B2B procurement and project delivery schedules |
Initial labeling issue on OM3 reels — resolved satisfactorily
Ordered 6,000 meters of OM3 multimode fiber for a storage area network project in Ohio. On arrival, approximately 15% of reels had mislabeled meter markings that didn't match the actual reel length, creating inventory tracking problems for our team. Raised the issue with the supplier immediately—they responded within 4 hours, issued corrected documentation, and offered partial credit on the next order. The fiber itself tested correctly against TIA-568.3-D OM3 specs: attenuation and bandwidth both within tolerance. The problem was administrative rather than product quality. Supplier's response was professional and the credit was honored.
