In environments where durability and high performance are crucial, such as mining, aerospace, military, and transportation, the application 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 use in the production of cables that require high-temperature stability.

j-fiber's optical fibers are coated with Polyimide, a material that is favored over traditional acrylate coatings, particularly in vacuum applications or where a thin coating layer is necessary. This advanced coating ensures that the fibers maintain their integrity and performance even in the most demanding environments. The Polyimide coating is not only robust but also provides a reliable solution for applications that require a high degree of precision and stability.

The optical fibers from j-fiber 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 such as step-index, large core, and high-NA. This versatility allows for a wide range of applications, ensuring that there is a suitable fiber for every need. With their superior temperature specifications and robust mechanical characteristics, j-fiber's optical fibers are the optimal choice for industries that demand the highest standards of performance and reliability.
