Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a ventilation device and a method for using the same. Background Art

[0002] Due to its excellent characteristics such as ultra-low loss, ultra-low dispersion, ultra-low non-linearity, and low delay, hollow-core optical fiber is an important candidate for the development of the next-generation ultra-large-capacity, low-latency, and high-speed optical communication systems.

[0003] Since the hollow-core optical fiber has a hollow structure inside, it is inevitable that air fills its interior during long-term storage. Gases such as water vapor, carbon dioxide, oxygen, and methane contained therein will all produce a photon absorption effect, causing additional gas absorption loss, which has a negative impact on high-speed long-distance hollow-core optical fiber signal transmission that is difficult to eliminate. Summary of the Invention

[0004] This application provides a ventilation device and a method for using the same, which are used to solve the problem that there are gases that can absorb photons inside the hollow optical fiber.

[0005] To achieve the above object, this application adopts the following technical solutions:

[0006] In a first aspect, an embodiment of this application provides a ventilation device for connecting to a hollow-core optical fiber, including a gas generation component and a gas discharge component. The gas generation component is disposed at one end of the hollow-core optical fiber and is in communication with the interior of the hollow-core optical fiber. The gas generation component is used to introduce a first gas into the hollow-core optical fiber; the first gas does not react with photons. The gas discharge component is disposed at the other end of the hollow-core optical fiber and is in communication with the interior of the hollow-core optical fiber. The gas discharge component is used to discharge the gas that reacts with photons inside the hollow-core optical fiber.

[0007] For the ventilation device provided by this application, the gas generation component is disposed at one end of the hollow-core optical fiber and is in communication with the interior of the hollow-core optical fiber, and can pass the first gas into the hollow-core optical fiber, and the first gas does not react with photons. By passing the first gas into the interior of the hollow-core optical fiber, the gas that can react with photons inside the hollow-core optical fiber can be discharged outward. The gas discharge component is disposed at the other end of the hollow-core optical fiber and is in communication with the interior of the hollow-core optical fiber, and can discharge the gas that reacts with photons inside the hollow-core optical fiber. By setting the gas discharge component, the gas inside the hollow-core optical fiber can be consumed, so that the air pressure at the end of the hollow-core optical fiber connected to the gas discharge component gradually decreases, which is beneficial for the first gas to quickly and fully fill the interior of the hollow-core optical fiber, and solves the problem that there are gases that can absorb photons inside the hollow-core optical fiber.

[0008] In some embodiments, the gas generation assembly includes a gas generator and a connecting pipe. The gas generator is used to generate a first gas. One end of the connecting pipe is connected to the gas generator, and the other end extends into the interior of the hollow core optical fiber. The first gas generated by the gas generator enters the interior of the hollow core optical fiber through the connecting pipe.

[0009] In some embodiments, the gas generation assembly further includes a first seal. The first seal is used to be installed at one end of the hollow core optical fiber, and the connecting pipe penetrates through the first seal.

[0010] In some embodiments, the number of connecting pipes and the number of first seals are multiple; one ends of the multiple connecting pipes are connected to the gas generator, and the other ends are respectively connected to a first seal and penetrate through the first seal.

[0011] In some embodiments, the first gas includes at least one of helium, neon, argon, krypton, xenon, and radon.

[0012] In some embodiments, the gas discharge assembly includes a gas discharger and a second seal. The gas discharger is used to discharge the gas that reacts with photons inside the hollow core optical fiber. The second seal is installed at the other end of the hollow core optical fiber. The other end of the hollow core optical fiber is connected to the gas discharger and penetrates through the second seal.

[0013] In some embodiments, the gas discharger includes a gas storage member and a gas consumer. A gas storage space is formed inside the gas storage member, and the other end of the hollow core optical fiber extends into the gas storage member. The gas consumer is disposed inside the gas storage space and is used to absorb the gas inside the gas storage space.

[0014] In some embodiments, the gas consumer includes a gas pumping device for pumping out the gas inside the gas storage space.

[0015] In some embodiments, the gas consumer includes a gas ignition device for igniting the gas inside the gas storage space.

[0016] In a second aspect, an embodiment of the present application provides a method for using a gas exchange device, which is used to discharge the gas that reacts with photons inside the hollow core optical fiber. First, the gas generation assembly and the gas discharge assembly are respectively installed at both ends of the hollow core optical fiber; then, the first gas is introduced into the hollow core optical fiber by using the gas generation assembly to discharge the gas inside the hollow core optical fiber to the gas discharge assembly; finally, the gas discharged from the hollow core optical fiber is consumed by using the gas discharge assembly.

[0017] According to the above technical means, after the gas generation assembly and the gas discharge assembly are installed at both ends of the optical fiber, the gas generation assembly generates the first gas, and the gas discharge assembly discharges the gas that reacts with photons. The operations at both ends are carried out simultaneously, which can accelerate the speed of filling the interior of the hollow core optical fiber with the first gas and improve the operation efficiency of the gas exchange device.

Rather, the use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner.

[0029] In a first aspect, embodiments of the present application provide a ventilation device, as Figure 1 shown, the ventilation device 100 is used to be connected to the hollow optical fiber 200, and includes a gas generation assembly 1 and a gas discharge assembly 2. The gas generation assembly 1 is disposed at one end of the hollow optical fiber 200 and is in communication with the inside of the hollow optical fiber 200. The gas generation assembly 1 is used to introduce a first gas into the hollow optical fiber 200; the first gas does not react with photons. The gas discharge assembly 2 is disposed at the other end of the hollow optical fiber 200 and is in communication with the inside of the hollow optical fiber 200. The gas discharge assembly 2 is used to discharge the gas that reacts with photons in the hollow optical fiber 200.

[0030] According to the above technical means, the gas generating component 1 is arranged at one end of the hollow fiber 200 and is in communication with the inside of the hollow fiber 200, and a first gas can be passed into the hollow fiber 200, and the first gas is a gas that does not react with photons. By passing the first gas into the inside of the hollow fiber 200, the gas that can react with photons inside the hollow fiber 200 can be discharged outwards to the gas discharging component 2. The gas discharging component 2 is arranged at the other end of the hollow fiber 200 and is in communication with the inside of the hollow fiber 200, and can discharge the gas that reacts with photons inside the hollow fiber 200. By arranging the gas discharging component 2, the gas inside the hollow fiber 200 can be consumed, so that the air pressure at the end of the hollow fiber 200 connected to the gas discharging component 2 gradually decreases, which is beneficial to the first gas quickly and fully filling the inside of the hollow fiber 200, and solving the problem that there is gas that can absorb photons inside the hollow fiber 200.

[0031] It can be understood that the air pressure of the first gas generated by the gas generating component 1 can be greater than the air pressure of the gas inside the hollow fiber 200, so that the first gas can enter the inside of the hollow fiber 200 by the action of pressure, and discharge the gas that reacts with photons inside the hollow fiber 200 to the gas discharging component 2.

[0032] In some embodiments, as Figure 1 shown, the gas generating component 1 includes a gas generator 11 and a connecting pipe 12. The gas generator 11 is used to generate the first gas. One end of the connecting pipe 12 is connected to the gas generator 11, and the other end extends into the inside of the hollow fiber 200. The first gas generated by the gas generator 11 enters the inside of the hollow fiber 200 through the connecting pipe 12.

[0033] It can be understood that the function of the connecting pipe 12 is to introduce the first gas generated by the gas generator 11 into the inside of the hollow fiber 200. Of course, the connecting pipe 12 can be replaced by a valve. Using a valve can control the flow rate of the first gas passing into the hollow fiber 200, but it will increase the complexity of the gas exchange device 100 and generate additional costs.

[0034] Exemplarily, the gas generating component 1 may not include the connecting pipe 12, one end of the hollow fiber 200 is directly communicated with the gas generator 11, and the first gas generated by the gas generator 11 is directly introduced into the inside of the hollow fiber 200 to discharge the gas that reacts with photons inside the hollow fiber 200.

[0035] In some embodiments, the gas generating component 1 further includes a first seal 13. The first seal 13 is used to be installed at one end of the hollow fiber 200, and the connecting pipe 12 penetrates through the first seal 13.

[0036] According to the above technical means, after the connecting pipe 12 penetrates through the first seal 13, it extends into the hollow optical fiber 200. The first seal 13 can seal the connection between the first connecting pipe 12 and the hollow optical fiber 200 to prevent the first gas generated by the gas generator 11 from leaking, which affects the working efficiency of the air exchange device 100.

[0037] Exemplarily, the first seal 13 can be made of materials such as sealant, anaerobic adhesive, heat shrinkable tube, epoxy resin, etc. The function of the first seal is to seal the connection between the first connecting pipe 12 and the hollow optical fiber 200 to prevent the first gas generated by the gas generator 11 from leaking.

[0038] In some embodiments, as Figure 2 shown, the number of the connecting pipes 12 and the number of the first seals 13 are multiple; one end of each of the multiple connecting pipes 12 is connected to the gas generator 11, and the other end is respectively connected to a first seal 13 and penetrates through the first seal 13.

[0039] According to the above technical means, the number of the connecting pipes 12 and the number of the first seals 13 are multiple, which can be connected to multiple hollow optical fibers 200, and the first gas can be introduced into the interiors of the multiple hollow optical fibers 200 at the same time. The air exchange device 100 can perform air exchange processing on multiple hollow optical fibers 200 simultaneously, improving the applicability of the air exchange device 100 and effectively improving the operation efficiency during mass operations.

[0040] Of course, the number of the first seals 13 can also be one, and a closed cavity is formed inside the first seal 13. At this time, after the multiple connecting pipes 12 are connected to the multiple hollow optical fibers 200, the connections between the multiple connecting pipes 12 and the multiple hollow optical fibers 200 are all connected to the closed cavity formed inside the first seal 13. In this way, one first seal 13 can also achieve sealing during the simultaneous air exchange processing of multiple hollow optical fibers 200.

[0041] In some embodiments, the first gas includes at least one of helium, neon, argon, krypton, xenon, and radon.

[0042] According to the above technical means, these inert gases have inactive chemical properties and are difficult to react with photons, and are commonly used protective gases in industry. Of course, the first gas can also be nitrogen. Nitrogen has inactive chemical properties and is difficult to react with photons at room temperature, and it is non-toxic itself and will not cause harm to the environment or the human body.

[0043] In some embodiments, as Figure 1As shown, the gas discharge assembly 2 includes a gas discharger 21 and a second seal 22. The gas discharger 21 is used to discharge the gas that reacts with photons inside the hollow fiber 200. The second seal 22 is installed at the other end of the hollow fiber 200. The other end of the hollow fiber 200 is connected to the gas discharger 21 and penetrates through the second seal 22.

[0044] According to the above technical means, one end of the hollow fiber 200 connected to the gas discharger 21 penetrates through the second seal 22. The second seal 22 can seal the connection between the hollow fiber 200 and the gas discharger 21, preventing external gas from entering the gas discharger 21 and the interior of the hollow fiber 200 and affecting the working efficiency of the gas exchange device 100.

[0045] Exemplarily, the gas discharge assembly 2 may not include the second seal 22. The function of the second seal 22 is to seal the connection between the hollow fiber 200 and the gas discharger 21 to avoid interference from external gas. The interior of the hollow fiber 200 can be directly connected and fixed to the gas discharger 21, and the gas discharger 21 directly consumes the gas that reacts with photons inside the hollow fiber 200.

[0046] In some embodiments, as Figure 1 shown, the gas discharger 21 includes a gas storage member 211 and a gas consumer 212. A gas storage space is formed inside the gas storage member 211, and the other end of the hollow fiber 200 extends into the gas storage member 211. The gas consumer 212 is disposed in the gas storage space and is used to absorb the gas in the gas storage space.

[0047] According to the above technical means, the gas consumer 212 can absorb the gas in the gas storage space. At this time, the air pressure in the gas storage space decreases, while the air pressure at one end of the hollow fiber 200 connected to the gas generating assembly 1 is high. Through the action of pressure, the first gas can quickly fill the interior of the hollow fiber 200, improving the working efficiency of the gas exchange device 100.

[0048] Exemplarily, the gas discharger may not include the gas storage member 211. The gas consumer 212 is directly connected to the interior of the hollow fiber 200 and directly consumes the gas that reacts with photons inside the hollow fiber 200, causing the first gas to quickly fill the interior of the hollow fiber 200.

[0049] In some embodiments, the gas consumer 212 includes a pumping device for pumping out the gas in the gas storage space.

[0050] According to the above technical means, the gas in the gas storage space is pumped out by the pumping device, gradually reducing the air pressure at one end of the hollow fiber 200 connected to the gas discharge assembly 2, which is beneficial for the first gas to quickly and fully fill the interior of the hollow fiber 200.

[0051] Exemplarily, the air extraction device includes a centrifugal fan, an axial flow fan, an inclined flow (mixed flow) fan, a cross-flow fan, etc. The air extraction device extracts the gas in the gas storage space, so that the first gas generated by the gas generating component 1 gradually fills the inside of the hollow optical fiber 200 under the action of pressure.

[0052] In some embodiments, the gas consumer includes a gas ignition device for igniting the gas in the gas storage space.

[0053] According to the above technical means, the gas in the gas storage space is consumed by the gas ignition device, so that the air pressure at one end of the hollow optical fiber 200 connected to the gas discharge component 2 gradually decreases, which is beneficial to the first gas quickly and fully filling the inside of the hollow optical fiber 200.

[0054] Exemplarily, the gas ignition device includes laser ignition, piezoelectric ignition, etc. The gas ignition device ignites and consumes the gas in the gas storage space that reacts with photons, so that the first gas generated by the gas generating component 1 gradually fills the inside of the hollow optical fiber 200 under the action of pressure.

[0055] In a second aspect, an embodiment of the present application provides a method for using a ventilation device 100 for discharging the gas in the hollow optical fiber 200 that reacts with photons. First, the gas generating component 1 and the gas discharge component 2 are respectively installed at both ends of the hollow optical fiber 200; then, the gas generating component 1 is used to introduce the first gas into the hollow optical fiber 200 to discharge the gas in the hollow optical fiber 200 to the gas discharge component 2; finally, the gas discharge component 2 is used to discharge the gas discharged from the hollow optical fiber 200.

[0056] The generation of the first gas by the gas generating component 1 and the discharge of the gas that reacts with photons by the gas discharge component 2 can be carried out simultaneously, accelerating the speed at which the first gas fills the inside of the hollow optical fiber 200.

[0057] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0058] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope defined by the claims.
