[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0024] The utility model provides a new boss optical fiber disk, which can be used to wind optical fibers and form different coiling radiuses and coiling lengths, so as to use a set of mechanical components to test the influence of different coiling radiuses and lengths on the optical parameters of the optical fibers.

[0025] Specifically, if Figure 1 The figure shows a schematic structural diagram of an embodiment of the raised platform optical fiber tray provided by the present invention. Figure 1In the illustrated embodiment, the raised fiber optic tray primarily comprises an upper cover plate 10, a tray body 20, and a lower cover plate 30. The tray body 20 comprises the tray top and a curved portion. The tray body 20 has a trapezoidal structure, with the bending radius and length (or circumference) of the tray body 20 gradually increasing from top to bottom. The upper cover plate is positioned above and fixedly connected to the tray top. The lower cover plate 30 is positioned below the tray body and sealed to the tray body via an O-ring. In other embodiments, the tray body may be raised above the lower cover plate 30, and the tray body 20 and lower cover plate may be integrally formed. In other embodiments, the tray body and lower cover plate may be connected in other ways, which are not limited here.

[0026] The upper cover plate 10 of the present invention is formed with a first fusion splice 101, and the lower cover plate 30 is formed with a second fusion splice 301. When testing an optical fiber, the fiber must first be wound around the outer surface of the optical fiber tray body 20 and powered to ensure proper operation. Therefore, the wound optical fiber must be connected to the first fusion splice 101 and the second fusion splice 301, respectively, to provide an external signal to ensure proper operation.

[0027] like Figure 2 The figure shows a cross-sectional schematic diagram of the upper cover provided by an embodiment of the present invention. In this embodiment, the upper cover comprises a first cover 102 and a second cover 103. The first cover 102 is a rectangular parallelepiped structure, while the second cover 103 includes a sloped structure. A first fusion splice is provided on the first cover 102. One end of the optical fiber is fused to the second fusion splice on the lower cover 30 and wound around the optical fiber tray. The other end of the optical fiber extends through the slope on the second cover 103 to the first cover 102 and is fused to the first fusion splice on the first cover 102. This arrangement reduces the bending amplitude of the portion of the optical fiber near the first fusion splice, preventing damage to the optical fiber. In this embodiment of the present invention, the first fusion splice 101 and the second fusion splice 301 can each be configured as a heat dissipation structure. This is because when the optical fiber is in operation, the fusion splice generates significant heat, causing the temperature to rise. Therefore, a heat dissipation structure, such as a heat sink, can be provided at the fusion splice to further dissipate heat.

[0028] In the embodiments provided by the present invention, the curved portion of the optical fiber tray can include multiple stacked fiber trays, each with a different bend radius and length (circumference), thereby forming a trapezoidal-shaped optical fiber tray body. Different types of optical fibers can be coiled and wound within the trays of varying sizes, facilitating subsequent testing of optical fibers with varying bend radii. Furthermore, because the optical fiber tray body is formed by stacking multiple trays, if a tray becomes damaged or requires replacement with a different bend radius, a single tray can be replaced without having to replace the entire tray body. The optical fiber tray body provided by the present invention offers a simple and stable structure and is relatively low cost.

[0029] In the above embodiment, the outer side surface of the fiber optic disc main body 20 is etched with a plurality of fiber optic grooves of different sizes; that is, the outer sides of the plurality of fiber optic discs are also etched with fiber optic grooves of different sizes, so that optical fibers of different sizes can be wound, which is suitable for more testing scenarios. Since the bending radius of the fiber optic disc main body 20 gradually increases from bottom to top, when the optical fiber is wound on the fiber optic disc main body 20, the bending radius of the optical fiber will also gradually decrease accordingly, thereby eliminating the high-order modes generated by the optical fiber under high power and ensuring the single-mode operation of the optical fiber. The fiber optic groove can also make the optical fiber fit better on the fiber optic disc main body, which is beneficial for the optical fiber to transfer heat to the fiber optic disc main body, thereby achieving the effect of heat dissipation. In the embodiment provided by the present utility model, the interior of the fiber optic groove can also be coated with a thermally conductive material to further dissipate heat from the optical fiber.

[0030] The interior of the fiber optic tray body 20 is a water-permeable cavity to dissipate heat from the optical fiber. Specifically, the fiber optic tray body 20 is sealedly connected to the lower cover plate 30 to form a hollow cavity, into which a liquid heat dissipation material, such as water, can be poured. A water inlet and outlet can be provided at the top of the fiber optic tray to allow water to be poured into the water-permeable cavity within the fiber optic tray. In other embodiments, an independent cooling loop can be provided within the internal accommodation space formed by the fiber optic tray body 20 and attached to the inner wall of the fiber optic tray body. By adjusting the temperature of the cooling material, such as water, in the cooling loop, the temperature of the optical fiber wound around the outer surface of the fiber optic tray body 20 can be adjusted. In the aforementioned embodiment, the cooling loop can be fixedly connected to the upper cover plate or the lower cover plate. When the fiber optic tray body is fixedly connected to the upper cover plate / lower cover plate, the cooling loop is attached to the inner wall of the fiber optic tray body 20. In other embodiments, the fiber optic tray body 20 itself may be formed with a water channel, which is formed inside the fiber optic tray body 20, or in other words, inside the fiber optic tray. Similarly, by adjusting the temperature of a cooling material, such as water, in the water channel, the temperature of the optical fiber wound around the outer surface of the fiber optic tray body 20 can be adjusted.

[0031] In the embodiment provided by the present invention, the lower cover plate 30 can also be a water-cooled plate, and a cooling water channel and corresponding cooling water channel water inlet and cooling water channel outlet are also formed in the lower cover plate 30. Generally speaking, when the lower cover plate is a normal support plate, the thickness of the lower cover plate is relatively small; however, when the lower cover plate is formed with a cooling water channel, the thickness of the lower cover plate is increased to form the cooling water channel.

[0032] In this embodiment of the present invention, the fiber grooves etched on the outer surface of the fiber optic reel have different sizes and circumferences, allowing testing of optical fibers of different sizes or specifications. For example, when testing an optical fiber, the fiber can be coiled into a fiber groove corresponding to the desired coil radius to perform a test at that coil radius; similarly, the fiber can be coiled into a fiber groove corresponding to the desired coil length to perform a test at that coil length.

[0033] Specifically, for the boss fiber optic reel provided by the present invention, a 400μm optical fiber can be wound into the first position of the boss fiber optic reel. The fiber coil radius of the boss fiber optic reel at the first position is 40mm to 106mm, the total length is 30.2m, the groove width and groove depth are 0.6mm, and the pitch is 1mm. A 600μm optical fiber can be wound into the second position of the boss fiber optic reel. The fiber coil radius of the boss fiber optic reel at the second position is 80 to 146mm, the total length is 31.2m, the groove width and groove depth are 0.9mm, and the pitch is 1.5mm. An 800μm optical fiber can be wound into the third position of the boss fiber optic reel. The fiber coil radius of the boss fiber optic reel at the third position is 100 to 172mm, the total length is 30.7m, the groove width and groove depth are 1.15mm, and the pitch is 2mm. At the same time, different fiber coils can be replaced in the present invention to form fiber optic reels of different sizes, making it suitable for more fiber optic testing scenarios.

[0034] The utility model also discloses an optical fiber water cooling device, which includes the boss optical fiber disk described in any of the above items, and a water cooler; the water cooler is respectively connected to the water inlet, water outlet and cooling water channel on the upper cover plate to circulate the liquid in the water cavity and the cooling water channel, thereby dissipating heat from the optical fiber.

[0035] The above is a detailed introduction to the embodiments of the present invention. Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, based on the idea of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the contents of this specification should not be understood as limiting the present invention.
