[0003] The existing hydrogen carrying system generally uses a hydrogen booster pump to inject hydrogen into the optical fiber storage device. Since hydrogen is a flammable and explosive gas, special attention must be paid to its handling. The booster equipment is not only complicated and dangerous, but also Equipment costs are also higher

[0064] In addition, based on the above-mentioned method for carrying hydrogen in the optical fiber, since there are multiple transition components 2, multi-stage hydrogen injection can be realized, and the gas pressure in the optical fiber storage chamber can be further increased. The second embodiment of the method for carrying hydrogen over optical fibers specifically includes:
[0065] In step (1), the fiber to be processed is loaded into the fiber storage chamber 13 .
[0066] Step (2), make the temperature of the transition chamber 12 of the transition assembly 2 of the previous stage lower than the temperature of the hydrogen cylinder 11, open the supply valve V1, and inject hydrogen from the hydrogen cylinder 11 to the transition chamber 12 of the transition assembly 2 of the previous stage. 11 and the transition chamber 12 of the transition assembly 2 of the upper stage are pressure balanced, and the supply valve V1 is closed.
[0067] Step (3), make the temperature o...

Description
technical field [0001] The invention relates to the field of optical devices, in particular to a self-pressurized fiber-optic hydrogen-carrying system and a fiber-optic hydrogen-carrying method thereof. Background technique [0002] The optical fiber hydrogen-carrying system is a sealed device that pretreats the optical fiber. The optical fiber is placed in the sealed device, the interior of the device is filled with high-purity and high-pressure hydrogen, and the device is stored for a period of time, during which the hydrogen molecules are under high pressure. The hydrogen-carrying system is mainly used in the pretreatment before the optical fiber is written. The gas pressure of hydrogen is the main technical parameter, and the gas with insufficient pressure will not be able to complete the hydrogen-carrying treatment. [0003] The existing hydrogen-carrying system generally uses a hydrogen booster pump to inject hydrogen into the optical fiber storage device. Since hydrog...
