| Property | Parameter | Description |
|---|---|---|
| Product Name | Low Bending Loss Fiber Optic Cable | Bend-insensitive single-mode / multimode optical fiber cable designed for tight routing applications |
| Fiber Grade / Type | G.657.A1 / G.657.A2 / G.657.B3 (SM); OM3 / OM4 (MM) | ITU-T G.657 bend-insensitive single-mode; IEC 60793-2-50 compliant multimode variants |
| Standard Compliance | ITU-T G.657, IEC 60793-2-50, IEC 60794-1, TIA-568.3-D | International standards for bend-insensitive fiber performance and cable construction |
| Core / Cladding Diameter | 9/125 µm (SM); 50/125 µm or 62.5/125 µm (MM) | Standard core-cladding geometry ensuring compatibility with existing network infrastructure |
| Attenuation | ≤0.20 dB/km @ 1550 nm; ≤0.40 dB/km @ 1310 nm (SM) | Low insertion loss per ITU-T G.657.A2 specification |
| Bending Loss (Macro) | ≤0.1 dB/turn @ R=15 mm (G.657.A1); ≤0.03 dB/turn @ R=10 mm (G.657.A2); ≤0.003 dB/turn @ R=7.5 mm (G.657.B3) | Significantly reduced macro-bending loss compared to standard G.652.D fiber |
| Numerical Aperture | 0.20 ± 0.02 (MM OM3/OM4); N/A for SM | Defines light-gathering ability of multimode fiber |
| Cable Construction | Loose tube / Tight buffer / Ribbon / ADSS / FTTH drop | Multiple construction options for indoor, outdoor, aerial, and duct installations |
| Jacket Material | LSZH / PVC / PE / HDPE | Low Smoke Zero Halogen preferred for indoor; PE/HDPE for outdoor UV-resistant applications |
| Cable Outer Diameter | 2.0 mm – 25.0 mm (depending on fiber count and construction) | Ranges from simplex drop cable to multi-fiber distribution cable |
| Fiber Count | 1 – 288 fibers per cable | Scalable configurations for FTTH, LAN, data center, and trunk applications |
| Operating Temperature | -40°C to +70°C (storage: -60°C to +85°C) | Suitable for extreme indoor and outdoor environmental conditions |
| Tensile Strength (Cable) | Short-term: ≤2700 N; Long-term: ≤1000 N (typical armored) | Per IEC 60794-1-2 Method E1; varies by cable type and armor configuration |
| Application | FTTH/FTTB last-mile, data centers, indoor wiring, MDU, tight-space routing | Ideal where sharp bends, small conduits, or high-density patching are required |
| Certification | RoHS, REACH, UL Listed (where applicable), CE, ISO 9001 | Compliance with environmental and safety regulations for global market access |
| Packaging | Wooden drum / Plastic reel: 500 m, 1000 m, 2000 m, 4000 m per reel | Standard reel lengths; custom lengths available upon request |
| MOQ | 1 km (standard); 500 m (sample order) | Flexible minimum order quantity for project procurement and trial evaluation |
Initial coating diameter query raised — resolved promptly
Ordered 10,000 meters of G.657.A1 cable for an enterprise campus network. On arrival, our QC team flagged coating diameter readings on two spools measuring 238 µm — slightly outside the 245 ±10 µm spec. We raised this with the supplier immediately. Their technical team responded within hours, acknowledged the variance, and arranged replacement spools dispatched within 5 business days. Attenuation and bend performance on all other spools were within spec. The issue resolution was handled professionally, and we would consider reordering based on that response.
