Embodiment Construction

[0019] The optical fiber fusion splicing structure and loss cloud detection system based on OCT technology includes two functional modules. The first is the OCT system module, which is used to realize the three-dimensional imaging of the optical fiber fusion splicing structure, and then uses the spectrometer to detect the loss spectrum of the optical fiber splicing. The specific implementation process of the OCT system module is that the frequency-sweeping laser 01 emits a light beam with a center wavelength of 1310nm and a bandwidth of 100nm, which is divided into two beams of light at a ratio of 10:90 by the fiber coupler 03 that is divided into two, and then enters the optical circulator one respectively. 03 and optical circulator 2 09; wherein 10% light of optical circulator 03 passes through three-paddle polarization controller 1 04 and scattering compensator 1 05, is focused by focusing lens 06 to dielectric film mirror 07, and then reflected to the optical ring according ...

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.
