Master control system is fed back to, high speed compares the measured diameter and control setting value of bare fibre, while being compared using this as control signal,
The essence of bare-fiber diameter is realized by the speed of feed speed and traction wheel of the accurate adjustment preform in fiber drawing furnace
Close control；The monitoring measuring device of coating diameter, real time high-speed measurement coating light are provided between application system and traction wheel
Fine diameter simultaneously feeds back to master control system, and high speed compares the measured diameter and control setting value of coated fiber, while with this to being compared to
To control signal, coating pressure is adjusted to realize that the accurate of optical fiber coating diameter controls by accurate.
With the rapid growth of Optical Fiber Market, optical fiber production efficiency is constantly promoted, and drawing speed is from original several hundred every point of rice
Clock is improved to 2000m/min or more, and optical fiber prefabricating rod production process and equipment are also constantly fast-developing, and single optical wand weight is continuous
Increase, increases to 100kg or more from original 10kg or so, the diameter of preform is increased to via original 60mm or so
200mm or more, the length of string of simple optical fiber prefabricated rods also increase to kilometers up to ten thousand by original 300 kilometers or so.With optical fiber
The fast development of prefabricated rods enlargement constantly proposes new challenge to drawing process, and fiber drawing furnace energy consumption also incrementally increases, especially
The direct wire drawing of large-scale female rod, it is more and more prominent that the non-round rate of bare fibre increases problem.The quick hair of FTTX, access net simultaneously
Exhibition, puts forward higher requirements the macrobend characteristic of optical fiber.
