Description

technical field [0001] The invention relates to a stretching device for a polymer optical fiber preform rod. Background technique [0002] my country's polymer optical fiber technology is backward. The existing polymer optical fiber manufacturing equipment has a low tower body and a simple drawing furnace structure. Generally, it can only draw thinner and shorter preforms, and the preforms are not heated uniformly in the drawing tower. As a result, the filament diameter of the polymer optical fiber is inconsistent, and the loss of the optical fiber is large, which cannot meet the requirements of large-scale production of low-loss and high-bandwidth optical fibers. Contents of the invention [0003] The key to the large-scale production of polymer optical fibers is the manufacture of high-quality preforms and high-precision preform drawing towers. The invention solves the technical problem of low-quality drawing polymer optical fiber in the polymer optical fiber drawing equ...
