[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying 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 them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] In addition, in the present utility model, words such as "first" and "second" are mainly used to distinguish one technical feature from another technical feature, and do not necessarily require or imply that there is a certain actual relationship, quantity or order between these technical features.

[0023] like Figure 1 and Figure 2As shown, the optical fiber switching frame in one embodiment of the utility model includes a plurality of optical fiber switching modules 10 and a wiring box 20 for installing the optical fiber switching modules 10. The optical fiber switching modules 10 and the wiring box 20 are generally installed inside the cabinet of the data center and are used for relaying and switching optical signals between Ethernet switches in the data center.

[0024] The wiring box 20 includes a bottom plate 21, a mounting plate 22 fixedly mounted to the bottom plate 21, two side plates 23 and a top plate 26. The mounting plate 22 is provided with a plurality of side-by-side mounting holes 221. The fiber optic switching module 10 includes a housing 11 and a first fiber optic adapter 12 mounted on the outside of the housing 11. The housing 11 is mounted inside the wiring box 20 and the first fiber optic adapter 12 passes through the mounting hole 221 and extends outward. A column 30 is mounted on one end of the side plate 23 close to the mounting plate 22. A baffle 40 for guiding air flow to the first fiber optic adapter 12 is mounted on the column 30. The column 30 is also provided with a slot for mounting the baffle 40.

[0025] In one embodiment, the baffle 40 is vertically arranged and located in the same plane as the mounting plate 22. Preferably, two baffles 40 are provided and are respectively located above and below the wiring box 20, so that the airflow can flow vertically through the first optical fiber adapter 12. At the same time, the airflow generated by the cooling system of the data center can further increase the airflow volume and flow rate flowing through the wiring box, thereby continuously and effectively dissipating heat and cooling, and is suitable for use in a data center room with a high optical fiber density.

[0026] like Figure 2 and Figure 3 As shown, the fiber optic switching module 10 also includes a second fiber optic adapter 13, an optical fiber 14 and two fiber optic connectors 15. The first fiber optic adapter 12 and the second fiber optic adapter 13 are respectively installed at two ends of the housing 11, and the optical fiber 14 and the two fiber optic connectors 15 are arranged inside the housing 11. The first fiber optic adapter 12 is connected to one end of the optical fiber 14 through a fiber optic connector 15, and the second fiber optic adapter 13 is connected to the other end of the optical fiber 14 through another fiber optic connector 15.

[0027] In one embodiment, the first optical fiber adapter 12, the second optical fiber adapter 13, the optical fiber 14 and the optical fiber connector 15 are all provided in 12 groups and arranged in a 2*6 matrix. The optical fiber 14 is specifically a 12-core optical fiber ribbon. Then, one optical fiber adapter module 10 has 144 optical fiber cores. Compared with the same type of optical fiber adapter modules on the market, the optical fiber density is higher. Four optical fiber adapter modules 10 are installed horizontally in a wiring box 20, and the height of each optical fiber adapter module 10 is 1U (the unit representing the external size of the server, which is the abbreviation of unit, and the size is specified by the American Electronics Industry Association (EIA), 1U = 4.445 cm). In other embodiments, the number and arrangement of the first optical fiber adapter 12, the second optical fiber adapter 13, the optical fiber 14 and the optical fiber connector 15 in the housing 11, and the number and arrangement of the optical fiber adapter modules 10 in the wiring box 20 can be determined according to actual conditions and needs.

[0028] The fiber optic switching rack designed in this solution has the ability to switch 576 optical signals in the size of a standard server, maximizing the fiber optic channel density in the limited space of 1U, fully meeting the construction needs of the new generation of 400G Ethernet data centers. Through highly integrated fiber optic channels and modular design, it solves the problems of limited space in data centers and increasing data exchange rate requirements, while supporting future upgrades to higher fiber density and higher rates.

[0029] In one embodiment, multiple distribution boxes 20 and fiber optic switching modules 10 can be stacked on top of each other to meet the higher fiber optic switching requirements of the data center. Preferably, when two distribution boxes 20 are stacked, a baffle 40 is placed between them and the distribution boxes 20 are stacked again, so that the fiber optic switching rack has a layout of baffle 40, two distribution boxes 20, baffle 40, two distribution boxes 20, baffle 40 from top to bottom. The space above the distribution box 20 and behind the baffle 40 can be used to install and accommodate equipment such as servers. This layout can widely meet the needs of fiber optic switching and wiring in the cabinets of the data center, making the lines neat and clear and making the most of the limited space in the cabinet.

[0030] like Figure 2 As shown, a partition 223 for forming a mounting hole 221 is formed on the mounting plate 22 , a third mounting portion is provided on the housing 11 of the fiber optic switching module 10 , and the housings 11 of adjacent fiber optic switching modules 10 are fixedly mounted to the partition 223 via the third mounting portion.

[0031] In one embodiment, the third mounting portion and the partition 223 are fixedly installed by bolts. On two adjacent fiber optic switching modules 10, the third mounting portion located between the two is installed on the same partition 223 in an up-and-down staggered manner. In this way, one partition can fix the two fiber optic switching modules 10 on both sides thereof, and the width of the partition only needs to be able to install one bolt. By shortening the width of the partition, the distance between the fiber optic switching modules 10 is further shortened, so that the optical fiber cables are arranged more closely, thereby maximizing the density of the optical fiber path. In other embodiments, the third mounting portion and the partition 223 can also be installed by means of snapping, gluing, etc.

[0032] like Figure 1 and Figure 2 As shown, a cable organizer 50 is installed on the wiring box 20. The cable organizer 50 includes a support plate 51 and a front side plate 52. Both ends of one side of the support plate 51 extend toward the mounting plate 22 and form an extension portion 511. The extension portion 511 is fixedly installed with the mounting plate 22. The extension portion 511 forms a ventilation slot 512 below the first optical fiber adapter 12. The front side plate 52 is installed on the other side of the support plate 51 through a hinge 53. The support plate 51 is provided with a snap-fitting portion, and the front side plate 52 is correspondingly provided with a buckle 54 for snapping the snap-fitting portion. The extension portion 511 is provided with a first mounting portion 512, and the mounting plate 22 is correspondingly provided with a second mounting portion 222. The first mounting portion 512 is fixedly installed with the second mounting portion 222.

[0033] By providing the ventilation slots 512, the airflow can flow vertically up and down without obstruction, so as to improve the heat dissipation and cooling capacity inside the cabinet. The front side panel 52 can be turned outward by the hinge 53, which is convenient for arranging and plugging and unplugging the optical cable. Since the first optical fiber adapter 12 is in the airflow surface guided by the baffle 40, after the first optical fiber adapter 12 is connected to the optical cable, the optical cable can avoid the airflow, avoid blocking the airflow and affecting the ventilation effect. The front side panel 52 can be kept upright by engaging the clamping part with the buckle 54, without affecting the normal operation of the data center.

[0034] Preferably, the first mounting portion 512 and the second mounting portion 222 are both protruding from the surface of the wiring box 20, and the first mounting portion 512 and the second mounting portion 222 are installed by bolts, which is convenient for assembly and does not occupy the space of the wiring box 20. The second mounting portion 222 can also be used to install the column 30, further saving space and accessories for installation.

[0035] A limit plate 24 for fixing the optical fiber adapter module 10 is fixedly mounted on the bottom plate 21, and the limit plate 24 is arranged correspondingly to the partition plate 223. The limit plate 24 can separate and limit the part of the optical fiber adapter module 10 located inside the wiring box 20, so as to prevent the optical fiber adapter module 10 from shaking inside the wiring box 20, causing problems such as loose cables.

[0036] A plurality of wire management brackets 25 are installed on the wiring box 20 . The wire management brackets include a fourth installation portion 251 , a bending portion 252 and a connecting portion 253 for connecting the fourth installation portion 251 and the bending portion 252 . The fourth installation portion 251 is fixedly installed with the limiting plate 24 or the side plate 23 .

[0037] In one embodiment, the cable management bracket 25 is arranged on the other side of the wiring box 20 opposite to the cable organizer 50. The cable organizer 50 is used to place and organize the optical fiber cables connected to the first optical fiber adapter 12, and the cable management bracket 25 is used to place and organize the optical fiber cables connected to the second optical fiber adapter 13. The bending portion 252 on the cable management bracket 25 can assist in fixing the cables to prevent the cables from loosening and sliding. The limiting plate 24 and the side plate 23 are both provided with a plane for installing the fourth installation portion 251. Since the limiting plate 24 and the side plate 23 are both arranged on both sides of the optical fiber adapter module 10, the optical fiber cables connected to the second optical fiber adapter 13 can be easily placed on a nearby cable management bracket 25, and the cable management bracket 25 plays a good supporting role.

[0038] In one embodiment, the bottom plate 21, the mounting plate 22, the side plate 23, the top plate 26, the limit plate 24 and the cable management bracket 25 on the wiring box 20 are all fixed and installed by bolts. The overall structure is simple, easy to install and maintain, which provides convenience for future equipment upgrades and replacement of accessories, and supports the upgrade and evolution of equipment to higher density and higher speed. In other embodiments, one or more of the above components can also be installed by integrated molding or other methods such as welding and splicing.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
