Abstract
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 by the deposition on the plastics layer an inorganic layer such as a non-stoichiometric composition of silicon and carbon or silicon and nitrogen.
