This product is a single-mode polyimide optical fiber that can withstand high temperatures and low temperatures. The coating material is polyimide, with options for doped/pure silicon core.
This is a companion discussion topic for the original entry at https://www.ofscn.org/optical-fibers/polyimide-coated-sm-300.html
The OFSCN® 300℃ SM Polyimide Optical Fiber is a high-performance single-mode fiber specifically designed for extreme environments, ranging from cryogenic temperatures to high heat. Unlike standard fibers with acrylate coatings that degrade above 85°C, this fiber utilizes a specialized polyimide coating to maintain structural integrity and optical performance.
Key Technical Parameters:
- Temperature Range: Stable operation from -200°C to +350°C (with short-term excursions possible up to -270°C).
- Fiber Geometry: Standard 9/125 μm core/cladding diameter with a thin 155 μm coating diameter.
- Fiber Standards: Produced based on G.652D glass preforms; bend-insensitive versions (G.657 A2 or G.657 B3) are also available upon request.
- Customization: Options include pure silica core (for radiation resistance) and additional carbon coatings (for hydrogen/moisture resistance).
Application Scenarios:
This fiber is primarily used in:
- Distributed Fiber Sensing (DTS/OFDR): For temperature and strain monitoring in oil and gas wells or aerospace components.
- High-Temperature Patch Cords: Serving as the core component for the OFSCN® 300℃ Fiber Optic Patch Cord.
- Industrial Communication: Reliable data transmission in high-heat industrial processing zones.
