Automatic optical fiber deuterium treatment equipment

Abstract

The invention relates to automatic optical fiber deuterium treatment equipment. The automatic optical fiber deuterium treatment equipment comprises a sealing treatment chamber, a vacuum pump, a deuterium inlet pipeline and a controller, wherein the sealing treatment chamber comprises a worktable, two side plates, a top cover, a front door and a back plate; the two side plates, the top cover and the back plate are fixedly connected to form an opening box with opened front surface and back surface; the worktable is slide forth and back on the bottom surface of the opening box; the front door is slide up and down on the front surface of the opening box; the whole sealing treatment chamber is a sealing box; the controller is electrically connected with the sealing treatment chamber, the vacuum pump and the deuterium inlet pipeline. The automatic optical fiber deuterium treatment equipment has the advantages that the optical fiber handling process and control process of traditional treatment equipment are changed, and the treatment process is basically automatic; the traditional whole sealing treatment chamber is changed, the scientific and reasonable sealing method is adopted, the automation requirement is met, and the sealing property of the sealing treatment chamber is guaranteed.

Description

technical field [0001] The invention relates to the field of optical fiber, in particular to an automatic optical fiber deuterium gas processing equipment. Background technique [0002] During the fiber drawing process, some disordered Si-O radicals will be generated, which can easily form Si-OH with H, resulting in an increase of the water peak at 1385nm. Therefore, all kinds of full-wave optical fibers must be treated with deuterium after drawing, so that they can withstand the erosion of the hydrogen-containing environment for a long time. [0003] The principle of deuterium treatment is to let deuterium and Si-O radicals form Si-OD, and the absorption peak is at 1850nm, so that hydrogen cannot replace the position of deuterium during the entire life of the fiber. Deuterium reacts with Si-0 radicals as follows [0004] Si-O + D2 → Si-OD [0005] According to the requirements of ITU-T G.652C / D, the attenuation coefficient of the optical fiber at 1383±3nm after hydrogen ...

Problems solved by technology

[0007] At present, the deuterium gas processing equipment is a closed container with an opening, and the opening has a sealed door that can be opened and closed. When processing deuterium gas, it is necessary to manually send the optical fiber into the sealed container with the help of a cart, which is time-consuming and laborious. Low level, low production efficiency
