Robust Multimode Fibers
With a core diameter of 50 µm, these germanium-free GI fibers can provide optimum transmission performance even in hydrogen-rich and radiation-intensive environments. Their unique glass chemistry and carbon coatings with high-temperature acrylate or polyimide can withstand temperatures of up to 150°C (acrylate) and 300°C (polyimide). These coatings are so robust that water, acid, and other liquids cannot penetrate the fiber. This prevents microcracks from forming on the core.
Since these robust fibers can withstand high pressure, moisture, chemicals, and radiation, they are used for measurement and monitoring technologies in oil and gas extraction.
