Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber lasers, in particular to a device for segmented synchronous texturing of optical fibers. Background Art

[0002] Fiber surface texturing is used in the production of fiber strippers, a key component of fiber lasers. The principle is to create a rough structure on the fiber surface using a chemical etching paste (texturing paste), disrupting the total internal reflection condition of the fiber cladding, thereby stripping a large amount of light entering the cladding. Optical stripping efficiency is related to the time and length of texturing. When used in the built-in stripper of a mode field adapter, fibers of different numerical apertures and core diameters at both ends of the splice need to be texturized according to performance requirements to achieve high stripping efficiency. However, existing texturing operations lack specific tooling and are achieved solely by contacting a handheld etching trough with the fiber surface. This relies heavily on operator proficiency and results in poor texturing consistency. Texturing multiple sections of fiber must be performed sequentially and cannot be performed simultaneously. This risks using an etching trough that only meets the specifications of the previous section, resulting in the subsequent section not meeting the texturing requirements. Texturing positions require manual determination of each fiber's position before etching begins, using a measuring tool. This is complex and carries the risk of poor positional consistency.

It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are only partial embodiments of the present invention and are not intended to be exhaustive.

It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0025] The following is a detailed description of the specific embodiments. It should be noted that the serial numbers of the following embodiments do not limit the preferred order of the embodiments. The utility model provides a device for segmented synchronous texturing of optical fibers. The device can not only texturize the optical fibers, but also perform different texturing treatments on different locations on an optical fiber at the same time. Specifically, Figure 1 The figure is a schematic diagram of the structure of the device for segmented synchronous hairpinning of optical fiber provided by the embodiment of the present utility model. Figure 1 In the embodiment shown, the device mainly includes the following structures:

[0026] The base 10 has a base groove formed thereon, and a guide rail is formed inside the base groove.

[0027] The etching groove 20 is multiple and is arranged inside the base groove and can move along the guide rail. The multiple etching grooves 20 are used to be filled with etching liquid to perform etching and roughening on the optical fiber.

[0028] The optical fiber fixing plate 30 is arranged above the corrosion groove 20. The top surface of the optical fiber fixing plate 30 is formed with a plurality of optical fiber fixing grooves for fixing optical fibers.

[0029] exist Figure 1 In the illustrated embodiment, the device for segmented, simultaneous texturing of optical fibers has a top-center-bottom structure. The base 10 can accommodate a varying number of etching tanks 20 of various sizes. The central etching tank 20 can be filled with etching liquid for texturing the optical fiber; the upper fiber holding plate 30 is primarily used to secure the optical fiber to be texturized. In the present invention, multiple etching tanks 20 are positioned within the base recess. Each of these multiple etching tanks 20 can be filled with different types of etching liquid, enabling simultaneous etching of different locations on the same optical fiber.

[0030] by Figure 1 Taking the illustrated structure as an example, the etching groove 20 may include two etching grooves, arranged parallel to each other within the base groove. The two etching grooves are filled with a first etchant and a second etchant, respectively. The first etchant can texturize the optical fiber to a first degree, while the second etchant can texturize the optical fiber to a second degree. When the optical fiber to be processed is fixed to the optical fiber fixing plate, the horizontal optical fibers and the longitudinal optical fibers are arranged perpendicularly, allowing the optical fiber to be immersed in the first and second etchants simultaneously. This allows texturization to be performed on different locations on the same optical fiber, thereby reducing texturization time and improving texturization efficiency. Therefore, in an embodiment of the present invention, multiple etching grooves 20 are arranged parallel to each other within the base groove, and the multiple etching grooves 20 need to be arranged perpendicular to the optical fiber fixing groove on the optical fiber fixing plate, so that a single optical fiber can contact multiple etching grooves 20 simultaneously.

[0031] Please continue to refer to Figure 1 ,exist Figure 1In the illustrated embodiment, a limit slot is formed on a side surface of the base 10 perpendicular to the horizontal plane. The base also includes a limit knob 101 and a limit rod (not shown). The limit knob 101 is mounted in the limit slot and connected to the limit rod. The limit rod is located below the etching groove and connected to the etching groove 20. The end of the limit rod is also mounted in the limit slot. The limit knob 101 is primarily used to control the limit rod's rotation, thereby moving the etching groove 20. Specifically, when the limit knob 101 is rotated, the limit rod also rotates. Since the limit rod is located below and connected to the etching groove 20, the rotation of the limit rod drives the etching groove 20. Since the etching groove 20 is connected to a guide rail formed within the groove of the base, the etching groove 20 can be moved along the guide rail under the drive of the limit rod. Since the optical fiber is fixed in the optical fiber fixing groove, the etching of the optical fiber at different positions can be achieved by moving the etching groove 20. In the present invention, there are multiple limit knobs 101 and limit rods, and the number of the multiple limit knobs 101 and limit rods is usually the same as the number of the multiple corrosion grooves 20; the multiple limit knobs 101, the multiple limit rods and the multiple corrosion grooves 20 are respectively arranged in a one-to-one correspondence, or one limit groove corresponds to one limit knob 101 and one limit rod.

[0032] In the embodiment of the present invention, the sizes of the plurality of etching tanks 20 can be different, and the etching liquids filled in the different etching tanks are also different, so as to perform etching of different specifications and types on optical fibers. Figure 1 Taking the two etching tanks 20 shown as an example, the left etching tank can be 3 cm wide and filled with a first etching solution, while the right etching tank can be 5 cm wide and filled with a second etching solution. Thus, different locations on the same optical fiber can be subjected to the first type of etching and texturing with an etching length of 3 cm, and the second type of etching and texturing with an etching length of 5 cm. Of course, the present invention can also be used to texturing optical fibers of different lengths by moving the etching tanks 20.

[0033] In some embodiments, multiple etching tanks 20 may include a target etching tank, which may include multiple sub-tanks, each of which is filled with different etching solutions. This means that one or more etching tanks 20 can be simultaneously filled with different etching solutions, allowing the same etching tank to be used for a variety of etching and texturing applications on the same optical fiber without adding more etching tanks or repeatedly filling the tank with different types of etching solutions. This reduces costs, simplifies the etching process, and improves etching efficiency. In the aforementioned embodiments, the multiple sub-tanks are typically arranged parallel to the direction of the optical fiber fixing groove.

[0034] In other embodiments, the target etching groove may also include multiple sub-grooves, but the multiple sub-grooves are usually arranged in parallel along a direction perpendicular to the optical fiber fixing groove. In this case, the multiple sub-grooves may be S-shaped structures. When the optical fiber is embedded in the sub-grooves, the length of the optical fiber embedded in the sub-grooves can be increased, thereby increasing the length of the optical fiber to be etched and roughened. Figure 2 The figure shows a top view of an embodiment of the etching groove provided in the embodiment of the present application. Figure 2 In the embodiment, the etching tank 20 includes a plurality of sub-tanks, each of which is an S-shaped structure and each of which is filled with different types of etching liquid. Figure 2 In the embodiment shown, different types of etching liquids are respectively filled in the multiple sub-troughs, but one optical fiber can only correspond to one sub-trough. Therefore, although multiple types of etching texturing can be performed simultaneously, it is not possible to perform multiple types of etching texturing on multiple optical fibers at the same time. If multiple types of etching texturing are desired on the same optical fiber, multiple etching tanks 20 are required to achieve this.

[0035] In the present invention, a plurality of fiber-holding grooves are formed above the fiber-holding tray 30 to secure multiple optical fibers. These grooves can vary in width and depth to accommodate optical fibers of varying specifications or types. The dimensions of the grooves can be tailored to the actual fiber dimensions of the product to ensure coaxiality between the two ends of the fiber. To secure the optical fiber, the ends can be secured to the left and right sides of the grooves with adhesive tape, reducing the risk of pressure loss. The coating of the secured fiber's midsection is then stripped to expose the quartz cladding. For subsequent etching and texturing, the fiber-holding tray 30, holding the optical fiber, is moved over the etching grooves and aligned with them before placement. The exposed quartz cladding must be positioned over the etching grooves for subsequent etching and texturing. The device for segmented, simultaneous optical fiber texturing provided by the present invention is easily disassembled, simple to clean, and convenient to move. It can simultaneously texturize ≤15 optical fibers. The number and width of the etching grooves can be adjusted to suit different usage scenarios, and the diameter of the fiber-holding grooves can be customized to ensure optimal fiber retention.

[0036] During the actual etching and texturing process, a significant amount of heat is generated, requiring heat dissipation. Therefore, in embodiments of the present invention, the apparatus for segmented, synchronous texturing of optical fibers may further include a heat dissipation layer, which may be attached to the outer surface of the etching grooves to dissipate heat. In other embodiments, the etching grooves themselves may be made of a metal heat dissipation material, such as copper or aluminum.

[0037] In the aforementioned embodiment, the bottom surface of the optical fiber fixing tray 30 is further formed with a plurality of support legs for supporting the optical fiber fixing tray. Specifically, when the optical fiber fixing tray 30 is placed on the etching tank 20, the plurality of support legs are required to support the optical fiber fixing tray 30 and ensure that the optical fiber fixed to the optical fiber fixing tray 30 can be immersed in the etching tank 20.
