Description

Technical Field

[0001] The embodiments of the present application relate to the field of optical communication technologies, and in particular, to an optical fiber box and an optical distribution network device. Background Art

[0002] With the development of the Optical Distribution Network (ODN) industry, box-type optical fiber boxes such as pre-connector boxes and pre-connected Fiber Access Terminals (FATs) are widely used.

[0003] Currently, large-capacity pre-connected fiber access terminals include more than 16 ports. Due to the dense port arrangement, the adapter ports cannot be integrally formed on the panel. Instead, multiple adapters are injection-molded one by one and fixed to the panel one by one by screwing, resulting in too high overall machine material and assembly costs. Summary of the Utility Model

[0004] The embodiments of the present application provide an optical fiber box and an optical distribution network device, which solve the problem of high cost of the optical fiber box.

[0005] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect of the embodiments of the present application, an optical fiber box is provided, including: a housing, a first optical fiber adapter assembly, and a first connection panel; the first connection panel is connected to the housing; the first connection panel includes: a plurality of first optical fiber adapters, wherein the plurality of first optical fiber adapters are integrally provided with the first connection panel, and the first optical fiber adapter assembly is connected to the first connection panel. Thus, the connection panel is divided into two parts, and only the two parts need to be formed separately and then connected together. Among them, the first connection panel and the plurality of first optical fiber adapters are integrally provided, and there is no need to individually install optical fiber adapter monomers on the first connection panel, reducing material costs and labor costs. The first optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, reducing the assembly difficulty.

[0007] In an optional implementation manner, the first optical fiber adapter assembly includes: 1 second optical fiber adapter. Thus, the structure of the first optical fiber adapter assembly is simple, reducing the injection molding difficulty and the assembly difficulty.

[0008] In an alternative implementation, the first optical fiber adapter assembly includes a second connection panel and a plurality of second optical fiber adapters, and the second connection panel and the plurality of second optical fiber adapters are integrally provided. Thus, the second connection panel and the plurality of second optical fiber adapters are integrally provided, eliminating the need to individually install single optical fiber adapters on the second connection panel, reducing material costs and labor costs. Moreover, the first optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, reducing the assembly difficulty.

[0009] In an alternative implementation, the plurality of first optical fiber adapters are arranged in a first direction, and the first optical fiber adapter and the second optical fiber adapter are arranged in a second direction. Thus, the first optical fiber adapter and the second optical fiber adapter are arranged in different rows. In the present application, the first part of the first connection panel and the first optical fiber adapter assembly are independently formed, that is, the first optical fiber adapter and the second optical fiber adapter are separately formed. Separating the optical fiber adapters in different rows that are relatively close reduces the injection molding demolding difficulty.

[0010] In an alternative implementation, the first optical fiber adapter and the second optical fiber adapter are arranged in a staggered manner in the first direction. Here, the staggered arrangement means that the first optical fiber adapter and the second optical fiber adapter are alternately arranged in the first direction, which can increase the spacing between the first optical fiber adapter and the second optical fiber adapter and reduce the assembly difficulty.

[0011] In an alternative implementation, the plurality of first optical fiber adapters are arranged in an arc shape. Thus, with a fixed connection panel size, arranging the plurality of first optical fiber adapters in an arc shape saves more space. Compared with arranging the plurality of first optical fiber adapters in a straight line, more first optical fiber adapters can be set, making full use of the space of the connection panel.

[0012] In an alternative implementation, the optical fiber box further includes a second optical fiber adapter assembly, and the second optical fiber adapter assembly is connected to the first connection panel. Thus, the connection panel is divided into three parts, and only need to form the three parts separately and then connect them together, reducing material costs and labor costs. The second optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, reducing the assembly difficulty.

[0013] In an alternative implementation, the second optical fiber adapter assembly includes one third optical fiber adapter. Thus, the structure of the second optical fiber adapter assembly is simple, reducing the injection molding difficulty and the assembly difficulty.

[0014] In an alternative implementation, the second optical fiber adapter assembly includes: a plurality of third optical fiber adapters and a third connection panel, and the third connection panel is integrally provided with the plurality of third optical fiber adapters. Thus, the third connection panel and the plurality of third optical fiber adapters are integrally provided, eliminating the need to individually install optical fiber adapter units on the third connection panel, reducing material costs and labor costs, and the second optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, reducing the assembly difficulty.

[0015] In an alternative implementation, the plurality of first optical fiber adapters are arranged along a first direction, and the first optical fiber adapter and the third optical fiber adapter are arranged along a third direction. Thus, the first optical fiber adapter and the third optical fiber adapter are arranged in different rows. In the present application, the first part of the first connection panel and the second optical fiber adapter assembly are independently molded, that is, the first optical fiber adapter and the third optical fiber adapter are separately molded, and the optical fiber adapters in different rows are separately molded, reducing the injection molding demolding difficulty.

[0016] In an alternative implementation, the first optical fiber adapter and the third optical fiber adapter are arranged in a staggered manner along the first direction. Among them, the staggered arrangement means that the first optical fiber adapter and the third optical fiber adapter are alternately arranged in the first direction, which can increase the distance between the first optical fiber adapter and the third optical fiber adapter and reduce the assembly difficulty.

[0017] In an alternative implementation, a first through hole is provided on the first connection panel, and the first optical fiber adapter assembly is arranged in the first through hole. Thus, the connection stability between the first optical fiber adapter assembly and the first connection panel is improved.

[0018] In an alternative implementation, the connection manner between the first optical fiber adapter assembly and the first connection panel includes: mechanical fixing, welding, and gluing. Thus, the first optical fiber adapter assembly and the first connection panel can be better connected.

[0019] In an alternative implementation, the first optical fiber adapter assembly is integrally formed by injection molding. Thus, material costs and labor costs are reduced.

[0020] In an alternative implementation, the optical fiber box includes: an optical fiber adapter unit, and the optical fiber adapter unit is connected to the first connection panel. Thus, the structure of the optical fiber adapter unit is simple, reducing the injection molding difficulty and the assembly difficulty.

[0021] In the second aspect of the embodiments of the present application, an optical distribution network device is provided, including: an optical fiber, and the optical fiber box as described above, and the optical fiber is connected to the optical fiber box. Thus, the optical distribution network device adopts the above optical fiber box, reducing material costs and labor costs. Description of the Drawings

[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0028] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0029] In addition, in the present application, orientation terms such as "upper" and "lower" are defined relative to the orientation of the components shown in the drawings. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they may change accordingly with the change of the orientation of the components placed in the drawings.

[0030] The present application provides an optical distribution network system, which is used to provide an optical transmission channel between an optical line terminal (OLT) of a central office device and an optical network unit (ONU) of a remote device in an optical access network (OAN). Among them, the optical access network refers to using optical fibers as the main transmission medium to realize the information transmission function of the access network.

[0031] Functionally, the optical distribution network system can be divided into four parts from the central office to the user end: a feeder optical cable subsystem, a distribution optical cable subsystem, a home optical cable subsystem, and an optical fiber terminal subsystem.

[0032] The optical distribution network system includes optical distribution network equipment, which may include, for example: optical fibers and optical fiber boxes. The optical fiber box includes: adapters, and the optical fibers are connected to the optical fiber adapters.

[0033] Figure 1 It is a schematic structural diagram of an optical fiber box. Figure 2 It is Figure 1 the top view of the optical fiber box in Figure 1 、 Figure 2 As shown in

[0034] The optical fiber box 10 includes: a housing 100, a connection panel 101, and a plurality of optical fiber adapters 102. The housing 100 is connected to the connection panel 101, and the plurality of optical fiber adapters 102 are connected to the connection panel 101.

[0035] In the embodiments of the present application, the connection manner between the optical fiber adapter 102 and the connection panel 101 is not limited. In some embodiments, each optical fiber adapter 102 is threadedly connected to the connection panel 101 respectively.

[0036] In order to further improve the connection stability, a sealing ring is provided between each optical fiber adapter 102 and the connection panel 101 respectively, and a torque can be applied to the optical fiber adapter 102 to lock the optical fiber adapter 102 on the connection panel 101, but the assembly cost of a single optical fiber adapter is relatively high.

[0037] In the embodiments of the present application, the forming manner of the optical fiber adapter 102 is not limited. The optical fiber adapter 102 can be formed by injection molding of a polymer material. However, the single-piece injection molding of the optical fiber adapter 102 has high assembly process requirements, long working hours, and high costs.

[0038] Therefore, the embodiments of the present application provide an improved optical fiber box. The connection panel of this optical fiber box is split into two or more parts for injection molding and then spliced, realizing an integrated structural form of the optical fiber adapter and the panel, and reducing the material cost and labor cost.

[0039] Figure 3 It is a schematic structural diagram of an optical fiber box provided by the embodiments of the present application. As Figure 3 shown, the optical fiber box includes: a housing 100, a first connection panel 11, a first optical fiber adapter assembly 12, and a plurality of first optical fiber adapters 110.

[0040] Among them, the first connection panel 11 is connected to the housing 100, the plurality of first optical fiber adapters 110 are integrally provided with the first connection panel 11, and the first optical fiber adapter assembly 12 is connected to the first connection panel 11.

[0041] The embodiment of the present application does not limit the connection manner between the connection panel and the housing 100. In some embodiments, the connection manner between the connection panel and the housing 100 includes: mechanical fixation or welding. Among them, mechanical fixation may include: fixed connection by screws, snap connection, etc.

[0042] Among them, the plurality of first optical fiber adapters 110 are integrally provided with the first connection panel 11, including: the plurality of first optical fiber adapters 110 and the first connection panel 11 are integrally injection molded, without installing the optical fiber adapter monomers one by one on the connection panel, reducing the material cost and labor cost.

[0043] The embodiment of the present application does not limit the structure of the first optical fiber adapter assembly 12. In some embodiments, the first optical fiber adapter assembly 12 includes at least one second optical fiber adapter 121, and the first optical fiber adapter 110 and the second optical fiber adapter 121 have the same structure, for example.

[0044] The first optical fiber adapter assembly 12 includes at least one second optical fiber adapter 121, that is, the second optical fiber adapter 121 may include one or more second optical fiber adapters 121.

[0045] In some embodiments, as Figure 5 shown, the second optical fiber adapter 121 is one, that is, the first optical fiber adapter assembly 12 only includes one second optical fiber adapter 121, and the second optical fiber adapter 121 monomer can be independently injection molded.

[0046] In other embodiments, as Figure 3 、 Figure 4 shown, the first optical fiber adapter assembly 12 includes a second connection panel 122 and a plurality of second optical fiber adapters 121, and the second connection panel 122 and the plurality of second optical fiber adapters 121 can be integrally injection molded.

[0047] The embodiment of the present application divides the connection panel into two parts, and only needs to connect the two parts together after molding them separately. Among them, the first connection panel and the plurality of first optical fiber adapters are integrally provided, without installing the optical fiber adapter monomers one by one on the first connection panel, reducing the material cost and labor cost. The first optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, reducing the assembly difficulty.

[0048] The embodiments of the present application do not limit the arrangement manner of the multiple first optical fiber adapters 110. In some embodiments, the multiple first optical fiber adapters 110 are arranged in an arc. Thus, when the size of the connection panel is fixed, arranging the multiple first optical fiber adapters 110 in an arc saves more space. Compared with arranging the multiple first optical fiber adapters 110 in a straight line, more first optical fiber adapters 110 can be provided, and the space of the connection panel can be fully utilized. The arrangement manner of the second optical fiber adapter 121 may refer to the arrangement of the first optical fiber adapter 110 to fully utilize the space of the second connection panel 122, which will not be elaborated here.

[0049] In some related technologies, the first connection panel 11, the multiple first optical fiber adapters 110, and the first optical fiber adapter assembly 12 are integrally injection-molded. When the distance between adjacent rows of optical fiber adapters is too close, the demolding difficulty is relatively high, and the requirements for the injection molding process are high.

[0050] Therefore, in some embodiments of the present application, the optical fiber adapters in different rows can be separately molded. For example, the first optical fiber adapter 110 and the second optical fiber adapter 121 can be arranged in different rows and separately molded.

[0051] In some embodiments, the multiple first optical fiber adapters 110 are arranged along a first direction, the first optical fiber adapter 110 and the second optical fiber adapter 121 are arranged along a second direction, and the multiple second optical fiber adapters 121 are arranged along a third direction, where the first direction is different from the second direction. That is to say, the first optical fiber adapter 110 and the second optical fiber adapter 121 are arranged in different rows. In some embodiments, the first direction and the third direction are substantially parallel, that is to say, the row where the first optical fiber adapter 110 is located and the row where the second optical fiber adapter 121 is located are parallel.

[0052] In the present application, the first part of the connection panel and the first optical fiber adapter assembly 12 are separately molded, so the first optical fiber adapter 110 and the second optical fiber adapter 121 are separately molded, that is, the optical fiber adapters in different rows are separately molded, reducing the injection molding difficulty.

[0053] The embodiments of the present application do not limit the positional relationship between the first optical fiber adapter 110 and the second optical fiber adapter 121. In some embodiments, the projections of the first optical fiber adapter 110 and the second optical fiber adapter 121 in the x direction can be staggeredly arranged. Among them, the staggered arrangement means that the projections of the first optical fiber adapter 110 and the second optical fiber adapter 121 in the x direction are alternately arranged, which can increase the distance between the first optical fiber adapter and the second optical fiber adapter, reduce the mutual interference between the first optical fiber adapter and the second optical fiber adapter, and reduce the assembly difficulty.

[0054] The embodiments of the present application do not limit the connection structure between the first connection panel 11 and the first optical fiber adapter assembly 12. In some embodiments, the first optical fiber adapter assembly 12 is embedded in the first connection panel 11. For example, a first through hole is provided on the first connection panel 11, and the outer shape of the first optical fiber adapter assembly 12 is adapted to the shape of the first through hole. The first optical fiber adapter assembly 12 can be disposed in the first through hole and connected to the first through hole.

[0055] In other embodiments, the first connection panel 11 and the first optical fiber adapter assembly 12 are two parts of the connection panel. For example, the first connection panel 11 and the first optical fiber adapter assembly 12 are arranged vertically in the y direction, and the first connection panel 11 and the first optical fiber adapter assembly 12 are respectively connected to the housing 100.

[0056] The embodiments of the present application do not limit the connection manner between the first connection panel 11 and the first optical fiber adapter assembly 12. The connection manner between the first connection panel 11 and the first optical fiber adapter assembly 12 includes: mechanical fixation, welding, and gluing.

[0057] In the above embodiments, the connection panel is divided into two parts and formed separately. In some embodiments, the connection panel can also be divided into three parts and formed separately. The optical fiber box further includes: a second optical fiber adapter assembly 13, and the second optical fiber adapter assembly 13 is connected to the first connection panel 11. Dividing the connection panel into three parts can reduce the size of a single adapter assembly and improve the structural stability of the optical fiber box.

[0058] In some embodiments, the second optical fiber adapter assembly 13 includes at least one third optical fiber adapter 131, that is, the third optical fiber adapter 131 can be one or more.

[0059] In some embodiments, the third optical fiber adapter 131 is one, that is, the second optical fiber adapter assembly 13 only includes one third optical fiber adapter 131, and the third optical fiber adapter 131 can be independently injection molded as a single unit.

[0060] In other embodiments, the second optical fiber adapter assembly 13 includes a third connection panel 132 and a plurality of third optical fiber adapters 131, and the third connection panel 132 and the plurality of third optical fiber adapters 131 can be integrally injection molded.

[0061] Thus, by dividing the connection panel into three parts, it is only necessary to form the three parts separately and then connect them together, reducing the material cost and labor cost. The positions and the number of optical fiber adapters of the first optical fiber adapter assembly 12 and the second optical fiber adapter assembly 13 of the connection panel can be adjusted according to requirements, reducing the assembly difficulty.

[0062] The embodiments of the present application do not limit the connection structure between the first connection panel 11 and the second optical fiber adapter assembly 13. In some embodiments, a second through hole is provided on the first connection panel 11, and the outer shape of the second optical fiber adapter assembly 13 is adapted to the shape of the second through hole. The second optical fiber adapter assembly 13 can be disposed in the second through hole and connected to the second through hole.

[0063] The embodiments of the present application do not limit the position of the third optical fiber adapter 131. In some embodiments, the optical fiber adapters in different rows can be separately formed. For example, the first optical fiber adapter 110 and the third optical fiber adapter 131 can be disposed in different rows, and the first optical fiber adapter 110 and the third optical fiber adapter 131 can be separately formed.

[0064] For example, the plurality of first optical fiber adapters 110 are arranged along a first direction, the first optical fiber adapter 110 and the third optical fiber adapter 131 are arranged along a third direction, and the first direction intersects the third direction. In some embodiments, the plurality of first optical fiber adapters 110 are generally arranged along the first direction, and the first optical fiber adapter 110 and the third optical fiber adapter 131 are generally arranged along the y direction. That is to say, the first optical fiber adapter 110 in the first connection panel 11 and the third optical fiber adapter 131 in the second optical fiber adapter assembly 13 are disposed in different rows. In the present application, the first connection panel 11 of the connection panel and the second optical fiber adapter assembly 13 are separately formed, so the first optical fiber adapter 110 and the third optical fiber adapter 131 are separately formed, that is, the optical fiber adapters in different rows are separately formed, reducing the injection molding difficulty.

[0065] In some embodiments, the projections of the first optical fiber adapter 110 and the third optical fiber adapter 131 in the x direction can be arranged in a staggered manner. The staggered arrangement means that the projections of the first optical fiber adapter 110 and the third optical fiber adapter 131 in the x direction are alternately arranged, which can increase the distance between the first optical fiber adapter and the third optical fiber adapter and reduce the assembly difficulty.

[0066] The following will be combined with Figure 3 , Figure 4 , Figure 5 to illustrate the structure of the optical fiber box of the present application.

[0067] In some embodiments, such as Figure 3As shown in the figure, the optical fiber box includes: a housing 100, a first connection panel 11, and a first optical fiber adapter assembly 12. The first connection panel 11 and the first optical fiber adapter assembly 12 can be connected together after being formed separately. Among them, the first connection panel 11 includes a plurality of first optical fiber adapters 110, and the plurality of first optical fiber adapters 110 are integrally provided with the first connection panel 11. The first optical fiber adapter assembly 12 includes: a second connection panel 122 and a plurality of second optical fiber adapters 121, and the plurality of second optical fiber adapters 121 are integrally provided with the second connection panel 122.

[0068] In this embodiment, the connection panel is divided into two parts: the first connection panel and the first optical fiber adapter assembly. It only needs to connect the two parts together after being formed separately. Among them, the first connection panel and the plurality of first optical fiber adapters are integrally provided, and there is no need to install the optical fiber adapter monomers one by one on the first connection panel, reducing the material cost and labor cost. Moreover, the second connection panel and the plurality of second optical fiber adapters are integrally provided, and there is no need to install the optical fiber adapter monomers one by one on the second connection panel, reducing the material cost and labor cost. And the first optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to requirements, further reducing the assembly difficulty.

[0069] Next, referring to Figure 3 , the plurality of first optical fiber adapters 110 are arranged in an arc, and the plurality of second optical fiber adapters 121 are also arranged in an arc. When the size of the connection panel is fixed, arranging the plurality of first optical fiber adapters 110 and the plurality of second optical fiber adapters 121 in an arc saves more space. When the size of the connection panel remains unchanged, compared with arranging the plurality of optical fiber adapters in a straight line, more first optical fiber adapters 110 can be set, making full use of the space of the connection panel.

[0070] In some examples of this embodiment, the first optical fiber adapter 110 and the second optical fiber adapter 121 are respectively arranged in different rows. The arcs of the plurality of first optical fiber adapters 110 and the arcs of the arrangement of the plurality of second optical fiber adapters 121 are, for example, arcs formed by concentric circles with different radii. In this application, the first optical fiber adapter 110 and the second optical fiber adapter 121 are formed separately, that is, the optical fiber adapters in different rows are formed separately, reducing the injection molding difficulty.

[0071] In some examples of this embodiment, the first optical fiber adapter 110 and the second optical fiber adapter 121 can be arranged in a staggered manner. Among them, the staggered arrangement means that the projections of the first optical fiber adapter 110 and the second optical fiber adapter 121 in the x direction are arranged alternately, which can increase the distance between the first optical fiber adapter and the second optical fiber adapter and reduce the assembly difficulty.

[0072] In some embodiments, such as Figure 4As shown in the figure, the optical fiber box includes: a housing 100, a first connection panel 11, a first optical fiber adapter assembly 12, a second optical fiber adapter assembly 13, and a plurality of first optical fiber adapters 110. Among them, the first connection panel 11 and the plurality of first optical fiber adapters 110 are integrally provided, and the first connection panel 11, the first optical fiber adapter assembly 12, and the second optical fiber adapter assembly 13 can be connected together after being formed separately.

[0073] For the optical fiber box provided in this embodiment, the connection panel is divided into three parts: the first connection panel 11, the first optical fiber adapter assembly 12, and the second optical fiber adapter assembly 13. It only needs to connect the three parts together after being formed separately, which reduces the material cost and labor cost. The installation position and the number of optical fiber adapters of the second optical fiber adapter assembly can be adjusted according to requirements, reducing the assembly difficulty.

[0074] Among them, the first optical fiber adapter assembly 12 includes: a second connection panel 122 and a plurality of second optical fiber adapters 121, and the plurality of second optical fiber adapters 121 are integrally provided with the second connection panel 122. When assembling the first optical fiber adapter assembly 12, it is not necessary to install the optical fiber adapter monomers one by one on the second connection panel, which reduces the material cost and labor cost, and the installation position and the number of optical fiber adapters of the first optical fiber adapter assembly can be adjusted according to requirements, further reducing the assembly difficulty.

[0075] The second optical fiber adapter assembly 13 includes: a third connection panel 132 and a plurality of third optical fiber adapters 131, and the plurality of third optical fiber adapters 131 are integrally provided with the third connection panel 132. When assembling the second optical fiber adapter assembly 13, it is not necessary to install the optical fiber adapter monomers one by one on the third connection panel, which reduces the material cost and labor cost, and the installation position and the number of optical fiber adapters of the second optical fiber adapter assembly 13 can be adjusted according to requirements, further reducing the assembly difficulty.

[0076] In some examples of this embodiment, the first connection panel 11 is provided with a first through hole and a second through hole. The first optical fiber adapter assembly 12 is disposed in the first through hole, and the second optical fiber adapter assembly 13 is disposed in the second through hole.

[0077] In some examples of this embodiment, the first optical fiber adapters 110 and the second optical fiber adapters 121 are respectively disposed in different rows, and the first optical fiber adapters 110 and the third optical fiber adapters 131 are disposed in different rows.

[0078] Exemplarily, the third optical fiber adapter 131 and the second optical fiber adapter 121 are substantially arranged in the same row, and the arrangement directions of the plurality of third optical fiber adapters 131 and the plurality of second optical fiber adapters 121 are parallel to the arrangement direction of the plurality of first optical fiber adapters 110. For example, the plurality of third optical fiber adapters 131, the plurality of second optical fiber adapters 121, and the plurality of first optical fiber adapters 110 are all arranged along the x direction. The arcs of the plurality of first optical fiber adapters 110 and the arcs formed by the arrangement of the plurality of second optical fiber adapters 121 are, for example, arcs formed by concentric circles with different radii, and the arcs of the plurality of third optical fiber adapters 121 and the arcs formed by the arrangement of the plurality of second optical fiber adapters 121 are, for example, arcs formed by concentric circles with the same radius. In this application, the first optical fiber adapter 110, the second optical fiber adapter 121, and the third optical fiber adapter 121 are separately formed, that is, the optical fiber adapters in different rows are separately formed, reducing the injection molding difficulty.

[0079] In some examples of this embodiment, the first optical fiber adapter 110 and the second optical fiber adapter 121 are arranged in a staggered manner, and the first optical fiber adapter 110 and the third optical fiber adapter 131 are arranged in a staggered manner. Among them, the staggered arrangement means that the projections of the first optical fiber adapter 110, the second optical fiber adapter 121, and the third optical fiber adapter 131 in the x direction are alternately arranged, which can increase the distance between the first optical fiber adapter and the second optical fiber adapter and reduce the assembly difficulty.

[0080] In still some other embodiments, as Figure 5 shown, the optical fiber box includes: a housing 100, a first connection panel 11, a first optical fiber adapter assembly 12, a second optical fiber adapter assembly 13, and a plurality of first optical fiber adapters 110. Among them, the first connection panel 11 and the plurality of first optical fiber adapters 110 are integrally provided, and the first connection panel 11, the first optical fiber adapter assembly 12, and the second optical fiber adapter assembly 13 can be respectively formed and then connected together. Different from Figure 4 is that the first optical fiber adapter assembly 12 includes: 1 second optical fiber adapter 121. The second optical fiber adapter assembly 13 includes: 1 third optical fiber adapter 131.

[0081] In some examples of this embodiment, the first connection panel 11 is provided with a first through hole and a second through hole. The first optical fiber adapter assembly 12 is arranged in the first through hole, and the second optical fiber adapter assembly 13 is arranged in the second through hole.

[0082] In some examples of this embodiment, the first optical fiber adapter 110 and the second optical fiber adapter 121 are respectively arranged in different rows, and the first optical fiber adapter 110 and the third optical fiber adapter 131 are arranged in different rows.

[0083] Exemplarily, the third optical fiber adapter 131 and the second optical fiber adapter 121 are substantially arranged in the same row, and the arrangement directions of the plurality of third optical fiber adapters 131 and the plurality of second optical fiber adapters 121 are parallel to the arrangement direction of the plurality of first optical fiber adapters 110. For example, the plurality of third optical fiber adapters 131, the plurality of second optical fiber adapters 121, and the plurality of first optical fiber adapters 110 are all arranged along the x direction. The arcs of the plurality of first optical fiber adapters 110 and the arcs formed by the arrangement of the plurality of second optical fiber adapters 121 are, for example, arcs formed by concentric circles with different radii, and the arcs of the plurality of third optical fiber adapters 121 and the arcs formed by the arrangement of the plurality of second optical fiber adapters 121 are, for example, arcs formed by concentric circles with the same radius. In this application, the first optical fiber adapter 110, the second optical fiber adapter 121, and the third optical fiber adapter 121 are separately formed, that is, the optical fiber adapters in different rows are separately formed, reducing the injection molding difficulty.

[0084] In some examples of this embodiment, the first optical fiber adapter 110 and the second optical fiber adapter 121 are arranged in a staggered manner, and the first optical fiber adapter 110 and the third optical fiber adapter 131 are arranged in a staggered manner. Among them, the staggered arrangement means that the projections of the first optical fiber adapter 110, the second optical fiber adapter 121, and the third optical fiber adapter 131 in the x direction are alternately arranged, which can increase the distance between the first optical fiber adapter and the second optical fiber adapter and reduce the assembly difficulty.

[0085] As described above, the above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered by the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
