| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | 50/125 µm Multimode Fiber Optic Cable | Graded-index multimode optical fiber cable with 50 µm core and 125 µm cladding diameter |
| Fiber Grade & ITU-T Classification | OM2 / OM3 / OM4 / OM5 (ITU-T G.651.1) | Compliant with ITU-T G.651.1 standard; OM3/OM4/OM5 optimized for laser-optimized multimode (LOMMF) |
| Core & Cladding Diameter Range | Core: 50 ± 2.5 µm; Cladding: 125 ± 1.0 µm | Tight dimensional tolerance ensures consistent coupling efficiency and low splice loss |
| Attenuation Coefficient at 850 nm | ≤ 2.3 dB/km (OM2); ≤ 2.0 dB/km (OM3/OM4/OM5) | Measured per IEC 60793-1-40; lower attenuation supports longer transmission distances |
| Attenuation Coefficient at 1300 nm | ≤ 0.6 dB/km | Applicable for dual-window multimode transmission; measured per IEC 60793-1-40 |
| Macrobending Loss Performance | ≤ 0.5 dB at R = 15 mm (100 turns, 850 nm) | Tested per IEC 60793-1-47; suitable for tight-bend installation environments |
| Chromatic Dispersion Coefficient | Zero dispersion wavelength: 850–950 nm range | Modal bandwidth dominates; chromatic dispersion ≤ 0.07 ps/(nm·km) at 850 nm for OM4 |
| Modal Bandwidth (Overfilled Launch) | ≥ 500 MHz·km at 850 nm (OM2); ≥ 1500 MHz·km (OM3); ≥ 3500 MHz·km (OM4) | Higher modal bandwidth enables 10G/40G/100G Ethernet over extended distances |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% end-face inspection and attenuation screening before shipment |
| Manufacturing Environment Standards | ISO 9001:2015 certified cleanroom; dust-free production line | Controlled temperature (23 ± 2 °C) and humidity (45–65% RH) during fiber drawing and cabling |
| Core Raw Material Source | High-purity silica glass (SiO₂ ≥ 99.99%); germanium-doped core | Preform manufactured via MCVD or OVD process; sourced from certified optical-grade silica suppliers |
| Packaging Specification | Standard reel: 500 m, 1000 m, 2000 m per spool; custom lengths available | Wooden or plastic reels with moisture-resistant wrapping; labeled with fiber type, length, and lot number |
| Storage Conditions | Temperature: -20 °C to +60 °C; Humidity: 10–85% RH (non-condensing) | Store away from direct sunlight and corrosive chemicals; keep reel upright to prevent deformation |
| Valid Shelf Life | ≥ 25 years (installed); ≥ 5 years (stored in original packaging) | Hermetic silica structure ensures long-term optical and mechanical stability under rated conditions |
| Application Scenarios | Data centers, LAN/SAN networks, 10G/40G/100G Ethernet, FTTA, indoor backbone cabling | Ideal for short-to-medium distance links up to 550 m (10GbE on OM3) and 400 m (10GbE on OM2) |
| Compliance & Certification | IEC 60793-2-10, TIA-492AAAC (OM3), TIA-492AAAD (OM4), RoHS 2011/65/EU, REACH | Third-party certified; CE marking available; halogen-free jacket options comply with IEC 60332-1 |
| Minimum Order Quantity (MOQ) | 1,000 m (single fiber); 500 m (duplex or ribbon cable) | Custom MOQ negotiable for OEM/ODM orders; sample reels (100 m) available for qualification testing |
| Monthly Supply Capacity | ≥ 500,000 m/month | Scalable production capacity supports large infrastructure projects and long-term supply agreements |
Initial coating issue on small portion of batch — supplier resolved promptly
Ordered 5,000 meters of OM3 50/125 multimode fiber for a hospital data center project in Boston. About 400 meters from one spool showed minor UV-cured acrylate coating irregularity that our technicians flagged during installation prep. We contacted the supplier immediately — they responded within 6 hours, issued a replacement spool within 10 days, and provided a written QC report explaining the root cause. Remaining 4,600 meters performed to full IEC 60793-2-10 spec. The after-sales response was genuinely good. Upgraded from initial concern; will give them another chance on next project.
