| Core & Cladding Diameter Range | Core: 8–62.5 μm; Cladding: 125 ± 0.7 μm | Tight-tolerance geometry for single-mode and multimode aerospace variants; hermetic coating available |
| Attenuation Coefficient at 1310 nm | ≤ 0.35 dB/km | Low-loss transmission at 1310 nm wavelength under aerospace thermal cycling conditions |
| Attenuation Coefficient at 1550 nm | ≤ 0.20 dB/km | Optimized for long-haul avionics data links and satellite communication systems |
| Macrobending Loss Performance | ≤ 0.10 dB at R = 15 mm (100 turns, 1550 nm) | Enhanced bend-insensitive design for tight routing in aircraft fuselage and spacecraft harnesses |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm | Dispersion-shifted or dispersion-flattened profiles available for high-speed avionics data buses |
| Batch Qualification Rate | ≥ 99.5% | 100% proof-test screening at ≥ 100 kpsi; full traceability documentation per batch |
| Manufacturing Environment Standards | ISO Class 5 (ISO 14644-1) Cleanroom | Controlled particulate and humidity environment; ESD-protected production lines for aerospace-grade consistency |
| Core Raw Material Source | Ultra-high-purity synthetic silica (SiO₂ ≥ 99.9999%) | Radiation-hardened and hydrogen-darkening-resistant preform; sourced from qualified aerospace-grade suppliers |
| Packaging Specification | Wooden drum or Al-alloy spool; 1 km / 2 km / 5 km per reel | Anti-static, moisture-barrier sealed packaging; shock-resistant for air freight and military logistics |
| Storage Conditions | Temperature: -40°C to +85°C; Humidity: ≤ 60% RH | Store away from UV exposure and corrosive gases; hermetic-coated variants tolerate H₂-rich environments |
| Valid Shelf Life | ≥ 25 years (hermetic coating); ≥ 20 years (standard acrylate) | Validated per MIL-STD-810 accelerated aging protocols; fatigue life tested to n = 20 stress corrosion parameter |
| Application Scenarios | Avionics, satellite payloads, UAV data links, space launch vehicles, military fiber-optic gyroscopes (FOG) | Suitable for fly-by-light systems, inertial navigation, high-radiation orbital environments, and hypersonic platforms |

| Minimum Order Quantity (MOQ) | 5 km (single-mode); 2 km (specialty/polarization-maintaining) | Custom short-length qualification samples available for aerospace program qualification phases |
| Monthly Supply Capacity | 500,000 km/month (standard); 50,000 km/month (PM/specialty) | Dedicated aerospace production lines with priority scheduling for defense and space program contracts |
Initial Shipment Had Documentation Gap — Resolved Promptly by Supplier
Our first order of 500 meters of polarization-maintaining fiber for a prototype gyroscope assembly arrived without the complete MIL-PRF-49291 traceability package — a compliance requirement for our customer's audit. We flagged this immediately and the full documentation set was emailed within 6 hours and a hard copy courier-shipped within 2 business days. The fiber itself tested well: extinction ratio above 30 dB and thermal stability confirmed to +280°C. Issue was resolved satisfactorily. Supplier acknowledged the process gap and confirmed an updated documentation checklist is now in place. Will trial a second order.
