Specialty Multi-Mode Radiation
Resistant Fibers
Nufern’s radiation resistant specialty multi-mode fibers are designed to operate for extended periods of time on low
earth orbits, near and deep space, and in applications where risk of exposure to man-made radiation is great. As with the
traditional Nufern MM fiber, these fibers are capable of withstanding extreme environments and large and fast temperature
swings. Features include step index and graded index configurations, numerical apertures from 0.06 to 0.45 and core sizes
from 10 μm to 700 μm. All fibers are available with a high temperature acrylate, silicone, or polyimide coating.
