Abstract

Embodiments of the present invention provide a method for controlling the drawing speed of an optical fiber, a control device, and an optical fiber drawing system, and relate to the field of optical fiber technology. Wherein, the control method of the fiber drawing speed includes: obtaining the diameter of the preform; obtaining the diameter of the annealed fiber body; calculating the current fiber drawing speed according to the feeding speed of the preform, the diameter of the preform and the diameter of the fiber body. The control device for the fiber drawing speed includes: a preform rod diameter acquisition module, an optical fiber body diameter acquisition module and a control module. According to the comparison between the current fiber drawing speed and the target fiber drawing speed, adjust the feeding speed of the preform rod by reducing the difference between the current fiber drawing speed and the target fiber drawing speed, so as to effectively improve the stability of the fiber production process and avoid fiber refraction Distortion of the rate profile, thereby obtaining attenuation, bandwidth and bending resistance close to the design value of the fiber.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a method for controlling the drawing speed of an optical fiber, a control device and an optical fiber drawing system. Background technique [0002] With the continuous growth of high bandwidth and high speed requirements of the network, optical fiber is widely used in network wiring as a network transmission medium. The common types of optical fiber are single-mode optical fiber and multi-mode optical fiber. Single-mode fiber refers to a fiber that can only transmit one propagation mode at an operating wavelength. Multimode optical fiber refers to the optical fiber whose working wavelength is multi-mode with its possible propagation modes. Since the transmission mode of multimode optical fiber can reach hundreds, the core diameter of multimode optical fiber is thicker than that of single-mode optical fiber, and the numerical aperture is larger. The light source couples mo...
