成果简介	NOVELTY - Group of inventions relates to fibre optics, namely to methods and devices for stretching sub-long-wave optical fibre. Method includes procedure of fibre preform preparation, fibre drawing, fibre gluing on fork and its packing into container. Operations are performed successively in one technological process in the fibre drawing zone and in the fibre gluing and packing zone. At that, transfer of fibre between zone of drawing and gluing and packing is performed by means of horizontal platform. Before the fibre drawing procedure, the fibre is pre-heated. In the drawing process, the oxygen-hydrogen burner nozzle swinging algorithm is used along the drawing axis with an initial swing amplitude of 1.5 160;mm, an amplitude increase factor for one period from 0.1 to 0.15 and a stretching rate from 0.1 160;mm/s to 0.2 160;mm/s. USE - Fibre optics. ADVANTAGE - High efficiency of making sub-long-wave optical fibre with an isthmus diameter of up to 400 160 nm and a transmission of about 80%.
