Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber drawing, in particular to an optical fiber drawing mechanism. Background Art

[0002] Fiber optic drawing, also known as fiber drawing, is a key step in the fiber optic manufacturing process. Simply put, this process is the process of heating and stretching the fiber optic preform into a filament.

In addition, the presence of particles will interfere with the propagation of light waves in the optical fiber, resulting in increased attenuation and scattering of the optical signal, thereby reducing the optical performance of the optical fiber. This may affect the transmission distance and signal quality of the optical fiber communication system. Utility Model Content
