FIELD: method and equipment for coating optical glass waveguide fiber. SUBSTANCE: method involves controlling viscosity profile of coating material in the region or in the vicinity of region defining diameter of coated fiber; regulating temperature of coating unit working member and, consequently, profile of coating material viscosity on the basis of measured diameter of coated fiber. EFFECT: increased efficiency in controlling amount of applied coating material and diameter of coated fiber, simplified method and construction. 14 cl, 6 dwg
