There were investigated the changes introduced by ionizing radiation in three different technological groups of optical fibres: i.MCVD low-loss and medium-loss optical fibres made from slightly doped high silica glasses for telecommunications purposes in UMCS Lublin, ii.PCS optical fibres designed for local area networks /LAN/ male by UMCS Lublin, iii.DC/TC optical fibres of high NA for instrumentation purposes, made from compound glasses by Glass Works Bialystok. Radiation investigations possessed completely different motivations for different groups of fibres. The basic aim of research referring to telecommunication fibres was: approximate determination of radiation sensitivity expressed in (d3/km.rad), looking for functional dependence between the quality of a fibre, its technological parameters and termical/radiation characteristics. Measurements of other fibres have been performed to gather directions concerning the problem how to increase this resistance against radiation environment. Following radiation characteristics have been presented and debated for three mentioned technological groups of optical fibres: spectral dependence of Losses for stated dose, attenuation dependence on dose and power of dose, relaxation processes, termically induced aniling processes, normalized radiation sensitivities.
