Abstract

The invention discloses a method and apparatus for processing an end face of a ribbon fiber. The apparatus comprises a fiber fixing device, a laser emitter, a spectroscope, a first holophote, a second holophote, a first collimating lens, a first beam expanding lens, a first field lens, a second collimating lens, a second beam expanding lens and a second field lens. Compared with the prior art, the apparatus divides the light beam emitted by the laser emitter into two paths, which are at a certain included angle, and are focused on the fiber end face after passing through a lens group. The fiber end face can be irradiated from two directions, so that the initial heating area of the fiber end face is more than doubled. The dwell time of the fiber end face in the heating area can be changed to obtain fiber end face with different forms. The fiber end face processing quality is substantially improved. The method and apparatus for processing the end face form of a ribbon fiber have the advantages of rapid speed, excellent correction effect and high correction precision.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a method and device for processing the end face of a ribbon-shaped optical fiber. Background technique [0002] Ribbon optical fiber is cut with an optical fiber cleaver. Due to the cutting principle of the cleaver, the end face of the optical fiber after cutting will be uneven, edge chipped and stubble broken, which will cause a large optical loss when the optical fiber is cold spliced ​​and thermally fused. At present, the ribbon-shaped optical fiber end-face treatment technology is in the development stage. The existing feasible technical solution is to use the high temperature of the discharge arc to melt the end-face of the optical fiber, so as to form a more ideal end-face shape. However, this technology is very difficult to control the temperature and width of the arc, and it is very easy to cause unstable discharge, which makes the shape of the process...
