The Influence Of Different Properties Based On The Optical Fiber Produced Procedure

As the national twelfth five-year strategic planning is pointed out in the ministry to develop "broadband of China" strategy,4G,5G,three nets and other major initiatives to develop,will directly pull the optical communications industry demand increase.Including optical fiber due to the large capacity of communication,transmission distance,high transmission quality,anti-interference,corrosion resistance,and many other advantages,has been widely used.In order to improve the yield and performance of optical fiber,the need for fiber drawing technology at home and abroad and the theory of drawing.Drawing speed of foreign countries to ultra high speed wire drawing tower(2000 m/min)above,the corresponding technology for WET ON WET coating way,some domestic fibre manufacturing enterprises to improve the yield and quality,need to increase the research of new technology of fiber drawing,especially pay attention to in the process of high-speed wire drawing a series of technology problems of induction and summary.Analysis on the cut off wavelength of single mode fiber drawing technology,mode field diameter,attenuation,the effects of various performance parameters,such as strength,appearance,draw the corresponding treatment measures and conclusion.The major work of the thesis is as follows:1.The existing optical fiber manufacturing process for analysis,Heating systems,cooling systems,as well as coating curing system for a detailed description.Described its structure and principle problem difficulties,and the portion of the fiber performance parameters are described to provide a basis for the subsequent optimization of design and process technology improvements.2.Fiber manufacturing process optimized system design,performance relates to the appearance of the optical fiber,the fiber strength Performance,and other aspects of the performance parameters of optical fiber,optical fiber preform and review mechanisms,cone control rod,the rod butt processes were optimized design.In the context of the current "broadband China","fiber to the home" of the national strategy,providing a steady stream of power production,and establish a brand value,enhance the competitiveness of the brand.3.Affecting the fiber appearance,optical parameter control,fiber production energy saving technology has done a lot of improvements.For example a curing lamp technology transformation,shading plate curing process modification,the fiber cladding / coating concentricity error control process improvement,as the wavelength control process transformation and so on,to ensure that the draw tower ultra high-speed running state and a high-quality product requirements,improve production efficiency,and improve product quality.
