Coated optical fibres and their manufacture

摘要

Manufacture comprises applying an electron beam-curable coating material to a glass optical fibre, then curing the coating material by irradiating with electron beam radiation accelerated at an accelerating voltage of not more than 150 kV. An independent claim is included for the coated optical fibre obtained by the process above. The coated fibre has a transmission loss after curing of 1-1.1 times the transmission loss prior to the electron beam irradiation.
