Optical fiber fusion splicing structure and loss cloud detection system based on OCT technology

Abstract

The invention provides an optical fiber fusion splicing structure and loss cloud detection system based on OCT technology. The system uses OCT technology to perform real-time, three-dimensional, fastand high-precision detection on optical fiber fusion splices, which can obtain full-view field structure information of the optical fiber fusion splices, including two-dimensional cross-section information and three-dimensional structure information, and realize accurate detection of practical problems such as fusion splicing dislocation and fusion splicing fault. At the same time, an optical fiber loss detection device consisting of a broadband light source and a spectrometer is used to detect and analyze the loss spectrum of the spliced optical fiber to further study the impact of differentoptical fiber fusion structures on its transmission loss and establish a database associated with the both, thereby providing strong digital technical support for the industrialized large-scale application of the optical fiber technology in the field of optical fiber communication and optical fiber sensing.
