Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical fiber end cap automatic alignment fusion splicing device and method based on optical power feedback. Background technique [0002] In high-power laser fiber transmission, the core diameter of the fiber is very thin, and the high-power laser is focused into the fiber through the lens. The power density of the fiber end face is extremely high, and the fiber is easily damaged. Therefore, the fiber end face is required to be free from any damage and pollution, which is extremely demanding; The area of ​​the end face is small, and it is not easy to carry out coating treatment. There is a large loss when the laser enters the end face of the uncoated fiber, which will generate more heat that damages the fiber; the strength of the two ends of the bare fiber is low during the installation and removal process, and the clamping is very uncomfortable. Convenience and...

AI Technical Summary

Problems solved by technology

One is the alignment of the optical fiber and the glass end cap. When the optical fiber and the glass end cap are welded with lateral misalignment or angle deviation, the transmission efficiency will be reduced, and the high-power laser will not meet the requirements for use; the other is the optical fiber and the glass end cap. The fusion splicing efficiency of the glass end cap, the alignment efficiency of the optical fiber and the glass end cap is low, so that the fusion splicing efficiency cannot be improved, and the production demand cannot be met
