Abstract : Several single-mode silica-based fibres with different levels of Erbium concentrations have been tested under 60Co gamma radiation. Irradiation has been performed at a dose-rate of ~30 Gy/h to a total dose of ~2kGy. Transmission spectra were measured in situ in a spectral range from 1250 to 1630 nm. The measurements show no detectable change in the Er-ions absorption, while a significant (~dB/m/kGy at 1530 nm) increase in transmission losses is attributed to silica host matrix modifications. This conclusion is drawn based on the post-irradiation photo-luminescence analyses.
