FIELD: physics.
SUBSTANCE: invention relates to methods of method chemical vapour deposition (MCVD) for making low-attenuation optical fibres for communication systems, sensors for physical quantities and transmission of powerful optical radiation. According to the method, the deposited glass layers of the core are doped with small additives of hydrogen or deuterium oxides with content of vapour of said substances in the gas phase from 0.017 to 1 mol %.
EFFECT: reduced viscosity of the glass of the core, preventing reduction of germanium dioxide.
