Thank you for sharing this information regarding high-temperature optical fiber requirements.

As noted, traditional optical fibers typically face coating degradation when temperatures exceed 85°C. For industrial environments in petroleum, power, and specialized sensing where temperatures reach mid-range levels, standard fibers are no longer reliable.

To address these challenges, we provide a specialized solution designed for stable performance in these conditions:

Featured Product: OFSCN® 120℃ SM High-temperature Optical Fiber

This fiber is specifically engineered to bridge the gap between standard telecommunication fibers and ultra-high-temperature fibers (like polyimide or metal-coated versions).

Key Technical Advantages:

• Temperature Range: Reliable operation from -50°C to +120°C.
• Specialized Coating: Utilizes a high-temperature resistant acrylate coating that maintains mechanical integrity and optical performance where traditional coatings fail.
• Standard Compatibility: Based on G.652D glass preforms (9/125/255μm), ensuring compatibility with standard fusion splicers and components while offering superior heat resistance.
• Optional Enhancements: Carbon coating can be added to provide an additional layer of protection against hydrogen darkening or moisture in harsh environments.

Standard Product Visuals:

This fiber serves as an ideal medium for both specialized communications and as a sensing element in distributed fiber optic sensing systems (DTS/DAS) operating in moderate heat.
