Abstract

The invention relates to online deuterium and nitrogen mixing equipment for lowering the hydrogen sensitivity of optical fibers, which comprises a nitrogen supply device, a deuterium supply device, a mixing ratio-variable gas mixer, a buffer tank connected with the mixer by pipe, a pipe pressure reducer connected with the buffer tank by a pipe and an optical fiber processing tank. For processing optical fibers, the invention provides a process device for mixing pressure deuterium on site in a factory, which simplifies the complex process of purchasing deuterium and nitrogen mixed gas and greatly reduces the deuterium/nitrogen mixing gas, thereby reducing deuterium processing cost and finally reducing production cost.

Description

technical field [0001] The invention relates to an on-site deuterium / nitrogen compounding device for reducing the hydrogen sensitivity of an optical fiber during the optical fiber manufacturing process. Background technique [0002] At present, optical fiber communication technology is developing towards high speed and large capacity. How to eliminate the OH ion absorption peak, find the fifth window of 1350-1450nm, develop low water peak optical fiber, and extend the working wavelength of single-mode optical fiber from 1260nm to 1625nm is becoming increasingly important. [0003] According to the standard of low water peak optical fiber, it is required to prevent the increase of additional loss after hydrogen loss after the optical fiber is molded. In this case, deuterium is used to treat the fiber to reduce the hydrogen sensitivity of the fiber. According to this theory, corresponding processing equipment has appeared at present, but at present, most optical fiber factor...
