| Property | Parameter | Description |
|---|---|---|
| Product Name | Specialty Optical Fibers for High-Temperature Applications | Single-mode and multimode optical fibers engineered for extreme thermal environments |
| Material Grade | Pure Silica Core / Fluorine-Doped Silica Cladding; Equivalent: Heraeus F300, Momentive HPFS 7980 | High-purity fused silica with low OH content or high OH content variants available |
| Standard Compliance | IEC 60793-2-50, IEC 60793-1-40, MIL-PRF-49291, Telcordia GR-20 | Compliant with international optical fiber performance and reliability standards |
| Core Composition | SiO₂ ≥99.99%; OH⁻ <1 ppm (low-OH) or OH⁻ 600–1200 ppm (high-OH) | Ultra-pure silica core minimizes transmission loss at elevated temperatures |
| Cladding Composition | F-doped SiO₂; Refractive Index Difference (Δn): 0.003–0.013 | Fluorine-doped cladding ensures stable numerical aperture under thermal stress |
| Coating Material | Polyimide (PI), Carbon + Polyimide, Gold, or Aluminum | Polyimide rated to 300°C; Gold/Aluminum coatings rated to 700°C continuous use |
| Operating Temperature Range | -60°C to +700°C (coating-dependent); Bare silica: up to 1000°C | Polyimide: up to 300°C; Al-coated: up to 400°C; Au-coated: up to 700°C |
| Tensile Strength | ≥50 kpsi (345 MPa) per IEC 60793-1-31 proof test | Standard proof test ensures mechanical integrity for installation and long-term use |
| Yield Strength | N/A (brittle material); Bend Radius: ≥10× fiber diameter (static) | Minimum bend radius specified to prevent microfracture and optical loss increase |
| Elongation | Fracture Strain: ≤1% (fused silica); Dynamic Fatigue Parameter n ≥20 | Low elongation characteristic of amorphous silica; fatigue resistance critical for longevity |
| Fiber Dimensions | Core Diameter: 50–600 µm; Cladding OD: 125–660 µm; Coating OD: 155–730 µm | Custom core/cladding ratios available; standard 125 µm cladding for telecom-compatible designs |
| Attenuation | ≤0.5 dB/km @ 1310 nm; ≤1.0 dB/km @ 850 nm (single-mode reference) | Attenuation may increase at elevated temperatures; characterized per IEC 60793-1-40 |
| Surface Finish / Cleave Quality | End-face surface roughness Ra ≤0.1 µm; Cleave angle ≤0.5° | Precision cleaving or polishing required for low-insertion-loss connectorization |
| Application | Industrial sensing, oil & gas downhole monitoring, aerospace, nuclear facilities, laser power delivery, distributed temperature sensing (DTS) | Suitable for environments where standard acrylate-coated fibers fail due to thermal degradation |
| Certification | RoHS 2011/65/EU, REACH SVHC compliant; ISO 9001:2015 manufacturing; MIL-SPEC available on request | Third-party test reports and material traceability documentation provided |
| Packaging | Spools: 100 m, 500 m, 1000 m, 2000 m; Custom lengths available; hermetically sealed packaging for gold/Al-coated fibers | Spools labeled with batch number, fiber type, coating, and test data sheet |
| MOQ | 100 m per fiber type; Custom orders from 1 m for prototype/R&D | Volume pricing available for orders ≥1000 m; lead time 2–6 weeks depending on specification |
Initial spool labeling issue — resolved promptly, fiber quality is solid
Ordered 600m of polyimide-coated 100/140 µm fiber for aerospace structural health monitoring at sustained 320°C. On arrival, two of five spools had mismatched batch labels versus the CoC documents, which created a traceability concern for our AS9100 audit. Raised the issue with customer support — corrected documentation and a written explanation were provided within 48 hours, satisfying our quality team. Fiber itself tested well: attenuation 0.98 dB/km at 1310 nm, proof-test certification at 100 kpsi confirmed. Issue appears to be an isolated labeling error. Will give another order a chance based on the responsive corrective action.
