Intent

This test procedure outlines methods for measuring both the steady state response of optical fibers and cables exposed to continuous radiation and the transient response of optical fibers and cables exposed to a pulse of radiation. It can be used to determine the level of radiation-induced attenuation produced in single-mode or multimode optical fibers, in either cabled or uncabled form. This test procedure is not intended to test the non-optical components of a fiber-optic cable. Other test methods may be required to evaluate the degradation of cable materials resulting from radiation exposure. The procedure specifically addresses steady state gamma-ray and neutron exposures, and transient gamma-ray, X ray, electron, and neutron exposures, but it would be applicable to other radiation sources (e.g., protons, heavy ions) as well, with appropriate changes in dosimetry and shielding considerations.]
