Results of pulsed gamma radiation tests are reported for Raychem and Dainichi-Nippon silica core fibres, and for an STC doped core fibre. Measurement conditions included temperatures from -55°C to +70°C, absorbed doses between 170 and 4200 rad(Si), photobleaching at optical powers from 0.04 μW to 360 μW, and a range of launch conditions and sample lengths. The selection of suitable test conditions is discussed, and results are compared with those for other radiation hard doped core fibres.
