Hydrogen Insensitive Core Graded-Index Multimode 50 µm Optical Fiber
This optical fiber is designed for distributed temperature sensing and communications in applications where hydrogen diffusion is a concern, and in temperatures up to 250 ºC for long durations (~ up to 20 years, performance and reliability will vary depending on installation environment. Consult Lightera for guidance). The waveguide features a proprietary, hydrogen insensitive core structure to minimize the effects of hydrogen darkening and also features a thin, hard, polyimide coating for excellent chemical resistance and thermal stability at elevated temperatures.
