Abstract
The investigation of the induced loss for a single-mode (SM) optical fiber under gamma -ray irradiation and neutron irradiation is described. An estimation method for induced loss with loss dose rate and long-term gamma -ray irradiation is proposed. The induced loss of pure-silica-core SM fiber is estimated to be 50 times lower than that of germanium containing silica-core SM fiber after irradiation with 1 R/h for 25 years.<>
