FIELD: physics.
SUBSTANCE: device for twisting optical fibres is equipped with a twisting roller device, which consists of a twisting roller device, which, through twisting the optical fibre, twists the fused part of the crude optical fibre, which is on the input side of the optical fibre; and a support part, which supports the twisting roller. Accuracy of the external circumference of the twisted roller, when the twisting roller forms part of the twisting roller device, is about 15 mcm or less.
EFFECT: prevention of linear distortions in the optical fibre during the stretching process and provision for a strong coating of the optical fibre.
