摘要： An optical fibre is provided with a moisture barrier layer by exposing a plastics coating on the fibre to a pulsed plasma in order to modify the surface, for instance by implantation of silicon, and/or to deposit on the plastics layer an inorganic layer for instance a non-stoichiometric composition of silicon and carbon or silicon and nitrogen.
