Description

technical field [0001] The invention belongs to the field of optical fiber equipment, and more specifically relates to a miniaturized functional fiber drawing equipment. Background technique [0002] Optical fibers are widely used in communication, laser transmission, sensing and other fields, and play an increasingly important role in human life. Optical fiber is usually produced by first preparing a preform, and then drawing the preform into an optical fiber through an optical fiber drawing device. At present, optical fiber drawing equipment has problems such as bulky size and high environmental requirements, and the materials that can be drawn by each drawing tower are relatively fixed. This has great limitations for us to study the regulation of multi-material fiber structure, morphology or performance, and to tap the potential power of optical fiber preparation technology. [0003] In practice, the demand for optical fibers for a single scientific research is very low...
