Description

technical field [0001] The invention relates to the field of optical fiber fusion end machines, in particular to a compact optical fiber fusion end machine imaging mechanism. Background technique [0002] In today's information age, with the rapid development of the Internet of Things and cloud computing, optical fiber communication has become the main force for information transmission. The optical communication system is mainly composed of four parts: the intercommunication backbone network, the metro The popularization of the network requires a large number of optical fiber connections. Among them, the access layer or terminal layer corresponding to the fiber-to-the-home (FTTH) project, the connection between the optical fiber and the splitter or switch is mainly a termination method. The mainstream method is the cold splicing solution: after cutting the optical fiber with a fiber cleaver, apply matching liquid on the fiber connection, and directly terminate on site. Thi...

Problems solved by technology

This method does not do any processing on the cut end face, and the end image cannot be observed clearly, which leads to uneven quality of optical fiber splicing and is difficult to control, and the later maintenance cost is high

[0003] Inspired by the simple operation and low loss of optical fiber thermal fusion, the market began to develop machines for thermal fusion modification of optical fiber ends. Existing fusion end machines can only support single-dimensional (side) observation of optical fiber end faces. If you want to intuitively understand and control To cut the surface details or defect state of the end face, and then control the yield rate of excellent end faces, it is necessary to add other optical path mechanisms or optical fiber end face detectors and other related equipment
