Paper Abstract

Fiber optic delay lines under =100 kpsi bend stress at 22 and -55°C were evalu-ated at 1300 nm during and after Co-60 irradiation and compared with similar multi-mode, low-OH, pure silica core/fluorosilica clad fibers under =10 kpsi bend stress. A very small, positive, =15% change in fiber attenuation (dB/km) was observed that suggests under high bend stress optical fibers may incur somewhat more radiation-induced attenuation than unstressed fibers. However, the influence upon overall radiation susceptibility of photonic systems deploying fiber optic delay lines with lengths up to 100 meters and under =100 kpsi stress should be negligible.
