| Property | Parameter | Description |
|---|---|---|
| Product Name | G.652B Matched-Cladding Single-Mode Optical Fiber | Standard single-mode optical fiber with matched cladding design for long-haul and access networks |
| Fiber Type / Grade | G.652B (equivalent to OS1/OS2) | ITU-T G.652B compliant; international equivalents include IEC 60793-2-50 B1.1, TIA-492CAAB |
| Standard Compliance | ITU-T G.652B, IEC 60793-2-50, TIA/EIA-492CAAB, GB/T 9771.1 | Meets international and Chinese national standards for single-mode optical fiber |
| Core / Cladding Diameter | Core: 8.6–9.5 µm; Cladding: 125.0 ± 0.7 µm | Matched-cladding structure ensures low splice loss and stable mode field |
| Mode Field Diameter (MFD) | 9.2 ± 0.4 µm @ 1310 nm; 10.4 ± 0.8 µm @ 1550 nm | Optimized MFD for compatibility with standard connectors and splicing equipment |
| Coating Diameter | 245 ± 10 µm (dual-layer acrylate coating) | Primary and secondary UV-cured acrylate coating for mechanical protection |
| Attenuation | ≤ 0.40 dB/km @ 1310 nm; ≤ 0.30 dB/km @ 1550 nm; ≤ 1.0 dB/km @ 1383 nm (water peak) | Low attenuation across O, E, S, C, L bands; G.652B does not require low water peak |
| Chromatic Dispersion | ≤ 3.5 ps/(nm·km) @ 1285–1330 nm; ≤ 18 ps/(nm·km) @ 1550 nm | Zero dispersion wavelength (λ0): 1300–1324 nm; dispersion slope ≤ 0.092 ps/(nm²·km) |
| Polarization Mode Dispersion (PMD) | PMD coefficient ≤ 0.5 ps/√km (link design value) | Suitable for transmission rates up to 10 Gbit/s per ITU-T G.652B requirements |
| Cutoff Wavelength | Cable cutoff wavelength (λcc) ≤ 1260 nm | Ensures single-mode operation across the full operating wavelength range |
| Tensile Strength (Proof Test) | ≥ 100 kpsi (≥ 0.69 GPa) | 100% proof tested; ensures fiber integrity and long-term mechanical reliability |
| Bend Performance | Macrobend loss ≤ 0.5 dB @ 1550 nm (100 turns, R=30 mm) | Compliant with ITU-T G.652B macrobend requirements for standard installation conditions |
| Operating Temperature | -60°C to +85°C (storage); -40°C to +70°C (operation) | Suitable for outdoor, indoor, aerial, and underground cable applications |
| Fiber Length / Packaging | Standard: 25 km / reel; custom lengths available (5–50 km/reel) | Wound on plastic or wooden reels; moisture-proof packaging with desiccant |
| Application | FTTH, FTTB, long-haul backbone, metro networks, data centers, CATV, telecom access | Widely used in terrestrial and submarine cable systems operating at 1310 nm and 1550 nm windows |
| Certification | ITU-T, IEC, TIA, RoHS, ISO 9001:2015 | Third-party certified; compliant with environmental and quality management standards |
| MOQ | 1 reel (≥ 25 km) | Bulk orders accepted; OEM and custom specifications available upon request |
Initial coating inconsistency — resolved promptly by supplier
Purchased 8,000 km of G.652B matched-cladding fiber for a metro network extension in Dubai. During incoming inspection, we identified coating diameter variation outside the 245 ± 10 µm spec on approximately 3% of reels from one production batch. We raised the issue immediately. The supplier's technical team responded within 4 hours, arranged replacement reels within 11 days, and provided updated IEC 60793-2-50 test reports for the replacement batch. All replacement fiber met ITU-T G.652B attenuation and MFD specs without exception. The resolution was handled professionally. We are proceeding with a follow-up order based on that response.
