S1550-HTA

Single-Mode Bend Insensitive Radiation Hardened Fiber

These pure silica core S1550-HTA fibers are single-mode fibers designed to be bend insensitive and withstand extreme pulsed and continuous ionizing radiation. They have high proof strength, large Weibull modulus, and superior dynamic fatigue parameter to maintain high mechanical reliability (long lifetimes). Available in both 125 and 80 µm clad diameters, they are ideally suited for special sensor applications or applications requiring coils. These fibers feature high temperature acrylate as standard coating to meet the challenges of the harsh tactical, avionics/aerospace, missile and UAV working environments.
