This topic discusses the technical specifications and applications of the OFSCN® 300℃ MM Polyimide Optical Fiber.

Based on the technical documentation, here are the core parameters for this multimode high-temperature resistant fiber:

Technical Specifications:

• Temperature Range: Operates stably from -200℃ to +350℃ (some variants support down to -270℃).
• Core/Cladding Diameter: Default 50/125μm or 62.5/125μm options available.
• Coating Diameter: 155μm (Polyimide coating).
• Fiber Core: Default doped core; pure silica core is available for customization (e.g., for radiation environments).
• Coating Material: High-performance Polyimide, which provides excellent thermal stability and mechanical strength. Carbon coating can be added upon request.

Applications:

This fiber is specifically designed for sensing and communication in extreme environments, such as aerospace, oil and gas downhole monitoring, and industrial high-temperature processing.
