| Property | Parameter | Description |
|---|---|---|
| Product Name | G.652.D Small-Diameter Single-Mode Optical Fiber | 200 μm outer coating diameter single-mode fiber for telecom and data networks |
| Fiber Type / Grade | ITU-T G.652.D (equivalent to OS2) | Standard single-mode fiber with low water peak; international equivalent: IEC 60793-2-50 B1.3 |
| Standard Compliance | ITU-T G.652.D; IEC 60793-2-50; TIA-492CAAB | Compliant with international telecom and fiber optic standards |
| Cladding Diameter | 125 ± 0.7 μm | Standard glass cladding diameter per ITU-T G.652.D specification |
| Core Diameter | 8.6–9.5 μm (nominal ~9 μm) | Single-mode core optimized for 1310 nm and 1550 nm wavelength operation |
| Outer Coating Diameter | 200 ± 5 μm | Reduced coating diameter vs. standard 250 μm; enables higher fiber density in cables |
| Coating Material | Dual-layer UV-cured acrylate | Soft inner primary coating + hard outer secondary coating for mechanical protection |
| Attenuation | ≤ 0.4 dB/km @ 1310 nm; ≤ 0.3 dB/km @ 1550 nm; ≤ 0.4 dB/km @ 1383 nm | Low water peak attenuation at 1383 nm per G.652.D; suitable for full-spectrum WDM |
| Mode Field Diameter | 9.2 ± 0.4 μm @ 1310 nm; 10.4 ± 0.8 μm @ 1550 nm | Per ITU-T G.652.D; ensures compatibility with standard SMF connectors and splices |
| Chromatic Dispersion | ≤ 3.5 ps/(nm·km) @ 1285–1330 nm; ≤ 18 ps/(nm·km) @ 1550 nm | Zero dispersion wavelength: 1300–1324 nm; suitable for high-speed transmission |
| Polarization Mode Dispersion (PMD) | ≤ 0.2 ps/√km (link design value) | Supports 10 Gbps and higher data rate transmission per G.652.D |
| Tensile Strength (Proof Test) | ≥ 100 kpsi (≥ 0.69 GPa) | Standard proof test level; optional 200 kpsi available for harsh environments |
| Operating Temperature Range | -60 °C to +85 °C | Suitable for indoor, outdoor, aerial, and duct cable applications |
| Spool / Packaging | Standard lengths: 5 km, 10 km, 25 km per spool; custom lengths available | Wound on plastic or wooden reels; moisture-resistant packaging for storage and transport |
| Application | FTTH/FTTX, long-haul telecom, high-density cables, data centers, WDM systems | Ideal for space-constrained cable designs requiring higher fiber count per unit area |
| Certification | ITU-T G.652.D; RoHS compliant; ISO 9001 manufacturing quality | Third-party test reports available; compliant with EU environmental directives |
| MOQ | 1 reel (minimum); bulk orders from 100 km | OEM and custom coating color options available for volume orders |
Initial reel labeling inconsistency caused sorting delays — issue was resolved promptly
We ordered 10,000 km of G.652.D 200μm fiber for a UK Openreach-aligned FTTH project. Fiber optical performance was fully compliant — attenuation ≤0.20 dB/km at 1550nm confirmed, PMD ≤0.10 ps/√km, proof test at 0.69 GPa verified. However, approximately 8% of reels arrived with reel length labeling that did not match internal spool markings, creating sorting delays at our warehouse. We raised the issue and the supplier's quality team responded within one business day, provided corrected documentation, and implemented a revised labeling check for our subsequent shipment. The replacement reels were accurate. Fiber quality itself is not in question — we will order again with this correction confirmed.
