FIELD: optics; technological processes.
SUBSTANCE: invention relates to methods and devices for radial pressing of soot for cladding optical fibre and, in particular, to methods and a device for production of optical fibre workpieces. Device has an outer wall and an inner wall. Outer wall surrounds inner wall and inner wall surrounds an inner cavity of device. Core rod is deposited in inner cavity after which particulate glass material, such as glass soot, is deposited in inner cavity around core rod. Core rod has at least 10 % of final cladding soot already applied thereto. Radially inward pressure is applied against particulate glass material to pressurise particulate glass material against core rod.
EFFECT: improved density and geometry of workpieces.
