Key Manufacturers and Products

Corning produces high-temperature fibers designed for single-mode and multimode applications, featuring optional hermetic carbon layers and high-temperature acrylate coatings. These fibers provide improved fatigue resistance, high usable strength, and resistance to hydrogen permeation, suitable for harsh environments . AFL offers Verrillon® harsh environment fibers, available with polyimide, silicone, silicone-PFA, and high-temperature acrylate coatings. Their single-mode fibers can operate in temperatures up to 500°C, with hermetic coatings that prevent hydrogen, moisture, and acid ingress. AFL also provides custom waveguide designs, including pure silica core and bend-insensitive fibers, widely used in downhole and industrial applications . WEINERT Industries AG manufactures fused silica-based fibers with heat-resistant coatings, supporting temperature ranges from −190°C to +385°C. Their German-engineered fibers are suitable for high-temperature industrial and scientific applications . Fujikura specializes in specialty single-mode fibers, including heat-resistant fibers coated with high-temperature acrylate. Their Thermally-diffused Expanded Core (TEC) fibers enhance mode field diameter during fusion splicing and are designed for demanding optical applications requiring thermal stability . Hengtong Group is a global optical fiber manufacturer offering a wide range of fiber solutions. While specific high-temperature single-mode fibers are not detailed, Hengtong provides customized technical solutions and has extensive experience in optical fiber production, making them a potential supplier for specialized high-temperature applications .

Considerations for Selection

When choosing a high-temperature single-mode fiber, consider:

• Temperature rating: Ensure the fiber coating and core can withstand the intended operating temperature (up to 500°C for some AFL fibers).
• Coating type: Options include polyimide, silicone, acrylate, or hermetic carbon layers for hydrogen and moisture resistance.
• Application environment: Downhole, aerospace, or industrial environments may require additional chemical or mechanical resistance.
• Fiber design: Single-mode, bend-insensitive, or pure silica core fibers may be necessary depending on optical performance requirements. These manufacturers provide fibers suitable for extreme temperature and harsh environmental conditions, supporting applications in energy, aerospace, and industrial sectors.
