Description

technical field [0001] The present application relates to the technical field of optical fiber preparation, and in particular, to a control device and method for improving the concentricity of a VAD optical fiber preform core package. Background technique [0002] As a medium for transmitting optical signals, optical fiber communication has many advantages such as large communication capacity, long transmission distance, small signal crosstalk, good confidentiality, anti-electromagnetic interference and good transmission quality, and plays a pivotal role in modern telecommunication networks. Optical fiber loss is one of the important indicators of optical fiber performance. The level of optical fiber loss directly affects the distance of communication transmission or the distance between relay stations and the performance of communication equipment such as SDH and WDM. The system cost is also mainly concentrated in the control loss. Therefore, Optical fiber loss has great pr...
