In environments where durability and reliability are paramount, such as mining, aerospace, and military applications, the use of optical fibers demands exceptional protection against extreme temperatures. j-fiber has engineered a range of optical fiber designs specifically for these challenging conditions, offering an impressive operating temperature range from -65°C to 300°C. This makes them ideal for industries that require high-temperature stability and robust performance.

One of the standout features of j-fiber's optical fibers is their Polyimide coating, which is favored over traditional acrylate coatings, particularly in vacuum applications or scenarios where a thinner coating layer is necessary. This specialized coating not only enhances the fiber's resilience in high-temperature environments but also ensures minimal mass loss, maintaining the fiber's integrity and performance even under strenuous conditions.

j-fiber's optical fibers are available in a variety of designs, including Singlemode G.652.D, G.657.A1/A2, and Multimode 50/125, 62.5/125, as well as specialty fibers like step-index and large core high-NA fibers. These options provide flexibility and adaptability to meet the specific needs of different applications, ensuring that users can find the perfect solution for their unique requirements.

With a focus on precision and quality, j-fiber's optical fibers are crafted with meticulous attention to geometrical and mechanical characteristics. The fibers feature a cladding diameter of 125 ± 2 µm and a coating diameter of 155 ±10 µm, ensuring consistent performance and reliability. This attention to detail, combined with the advanced Polyimide coating, makes j-fiber's optical fibers a top choice for demanding environments where high performance is non-negotiable.
