| Property | Parameter | Description |
|---|---|---|
| Product Name | Single Mode Bend Insensitive Fiber | Low-bend-loss single mode optical fiber designed for tight routing applications |
| Fiber Type / Grade | G.657.A1 / G.657.A2 / G.657.B3 | ITU-T compliant bend-insensitive SMF; equivalent to Corning ClearCurve, OFS BendBright |
| Standard Compliance | ITU-T G.657, IEC 60793-2-50, TIA-492AAAD | Fully backward compatible with ITU-T G.652.D standard single mode fiber |
| Core Diameter | 8.6 – 9.5 µm | Nominal core diameter optimized for single mode transmission at 1310/1550 nm |
| Cladding Diameter | 125.0 ± 0.7 µm | Standard 125 µm glass cladding for compatibility with standard connectors and splices |
| Coating Diameter | 245 ± 5 µm (standard) / 200 µm (reduced) | Dual-layer acrylate coating; 200 µm option available for high-density cable designs |
| Attenuation | ≤ 0.35 dB/km @ 1310 nm; ≤ 0.20 dB/km @ 1550 nm | Low attenuation per ITU-T G.657; water peak attenuation ≤ 0.4 dB/km @ 1383 nm |
| Macrobend Loss (G.657.A2) | ≤ 0.03 dB/turn @ R=15 mm (1550 nm); ≤ 0.1 dB/turn @ R=10 mm (1550 nm) | Significantly reduced bend-induced loss vs. G.652.D; suitable for FTTH drop cables |
| Macrobend Loss (G.657.B3) | ≤ 0.03 dB/turn @ R=7.5 mm (1550 nm) | Ultra-low bend loss for extreme tight-bend routing in premises and indoor installations |
| Numerical Aperture | 0.14 ± 0.02 | Standard NA ensuring compatibility with G.652.D splicing and connector systems |
| Zero Dispersion Wavelength | 1300 – 1324 nm | Per ITU-T G.657 / G.652.D specification |
| Cable Cutoff Wavelength | ≤ 1260 nm | Ensures single mode operation across full O to L band (1260–1625 nm) |
| Operating Temperature | -60°C to +85°C | Suitable for indoor, outdoor, aerial, and duct deployment environments |
| Application | FTTH/FTTX, indoor wiring, MDU, data centers, tight-buffer cables | Ideal for last-mile access networks, bend-sensitive routing, and high-density installations |
| Certification | RoHS, REACH, UL (optional), CE | Compliant with international environmental and safety regulations |
| Packaging | Wooden reel: 2.5 km, 5 km, 10 km, 25 km per reel | Standard wooden or plastic reels; custom lengths available upon request |
| MOQ | 1 reel (2.5 km) | Flexible order quantities; OEM and custom specifications supported |
Initial reel labeling inconsistency — resolved promptly, fiber itself is good
Ordered 15,000 m for a campus network upgrade. On arrival, four reels had mismatched batch numbers on the outer label versus the internal documentation, which flagged a concern during our incoming QA inspection. I contacted support and received corrected traceability documents within 36 hours along with a clear explanation. The fiber optical performance — attenuation ≤ 0.20 dB/km at 1550 nm, proof test at 100 kpsi — tested correctly on all reels. The issue was administrative, not product quality. They've since confirmed improved labeling QC. Would consider reordering.
