Neutron- and Gamma-Induced Transient Effects in Optical Fibers

An Analysis of Photobleaching Techniques for the Radiation Hardening of Fiber Optic Data Links

“…The spectral nature and magnitude of these losses as a function of radiation environment have been characterized for most state-of-the-art optical fibers.
