Optical fibers with various protective coatings were submerged in liquid nitrogen to 77°K then tested for mechanical and optical reliability. While all the fibers maintained strength after low-temperature exposure, the optical response varied depending on the protective coating.|Optical fibers with various protective coatings were submerged in liquid nitrogen to 77°K then tested for mechanical and optical reliability.
