Abstract

The invention discloses a laser scanning and heating fusion splicing mechanism of an optical fiber fusion splicer for the fusion splicing of optical fibers different in material and core-diameter. The laser scanning and heating fusion splicing mechanism comprises a laser unit. The laser output port of the laser unit is provided with a galvanometer. The front end of the galvanometer is provided with a field lens. A laser beam emitted by the laser unit is subjected to the scanning of the galvanometer and the focusing of the field lens to form laser light spots and then the laser light spots are outputted. According to the technical scheme of the invention, the laser unit is used as a fusion splicing heat source, and the galvanometer and the field lens are used for outputting, scanning and focusing the laser. The step-by-step fusion splicing of optical fibers different in material and core-diameter is realized through controlling the laser output power and the field lens. Therefore, the synchronous softening of the optical fibers is achieved. The laser scanning and heating fusion splicing mechanism has the advantages of rapid fusion splicing, good fusion splicing effect and the like.

Description

technical field [0001] The invention relates to the field of optical fiber welding, in particular to a laser scanning heating welding mechanism of an optical fiber welding machine suitable for welding optical fibers of different materials and different core diameters. Background technique [0002] With the continuous development of optical communication and optoelectronic technology, various new types of optical fibers and optical fibers with different core diameters have been continuously developed, and a big problem that follows is the connection between these optical fibers of different thicknesses and different materials. At present, the following two connection methods are basically used in the industry: [0003] 1. Cold splicing: use ceramic ferrules and sleeves to align and fix optical fibers of different materials through a mechanical structure. This method has large insertion loss and poor return loss, is expensive, and has poor connection effect. There is an inter...
