Description

Technical Field

[0001] The utility model relates to the technical field of optical communication equipment, and in particular to an optical component and an optical module that can be applied across media. Background Art

[0002] With the development of optoelectronic devices and the improvement of integration, the demand for high-bandwidth, high-speed and small-size optical modules is also increasing. At the same time, the optical modules of data centers are constantly upgraded, and the traffic data is growing rapidly, which is also constantly promoting the upgrading and innovation of data center architecture. With the deployment of large-scale 400G high-speed ports, 800G interconnection in data centers will also become a new demand; with the continuous expansion of data centers and the continuous improvement of computing power, the density of cabinet power will also increase accordingly, and the field of data center temperature control will also change. It will be a general trend for traditional air cooling to be replaced by cross-media applications. At present, optical modules have a variety of packaging structures. Among them, in BOX packaging, the optical device is completely sealed in a packaging box filled with dry nitrogen. Its good sealing can not only isolate the influence of liquid cooling materials on optical devices, but also has the advantages of good moisture resistance, small thermal expansion coefficient and high thermal conductivity under the premise of complete sealing, which can perfectly adapt to the future packaging trend.

[0003] However, in multi-channel application scenarios, some good solutions are still needed to address the sealing issues of multiple fibers. For example, in existing multi-fiber optical modules (such as 800G DR8 optical modules equipped with 16 optical fibers), multiple fibers are usually arranged in an array to form one or more fiber array modules. Existing optical modules are usually equipped with a housing, a fiber interface, a fiber array module, an optical submodule (OSA), an electronic submodule (ESA), etc., wherein the optical submodule usually includes an optical transmitter submodule (TOSA), an optical receiver submodule (ROSA) and / or an optical transmitter and receiver submodule (BOSA), and the electronic submodule usually includes a circuit board and a chip, etc. In BOX packaging, the optical submodule is usually packaged in a packaging box, and one side of the packaging box is provided with an optical window for signal passage, such as Figure 1 As shown, the existing light window usually includes a light channel penetrating the side wall of the packaging box and a lens arranged in the light channel, and the lens is usually arranged in the middle of the light channel, such as Figure 1 As shown, in some optical modules, the end of the optical channel is flush with the side wall of the packaging box, such as Fig. 9 As shown, in other optical modules, the light window also includes an external window sill arranged outside the packaging box and an internal window sill arranged inside the packaging box, and the light channel runs through the external window sill and the internal window sill, such as Figure 1 As shown, in the existing optical module, the optical fiber array module is usually fixed in the housing by a separate bracket, and the end of the optical fiber array module corresponds to the optical channel of the optical window, such as Figure 2 and Figure 3As shown, the optical fiber in the optical fiber array module is facing the lens. From the structure of the optical window, it can be seen that there is an optical channel between the end of the optical fiber array module (or the end of the optical fiber) and the lens. In conventional applications, this optical channel is filled with air (a medium). When the signal passes through the air, there is a loss, which is not conducive to the transmission of the signal. In addition, the matching structure between the optical fiber array module and the packaging box in the existing optical module does not take into account the sealing between the optical fiber and the lens, resulting in a gap between the optical fiber array module and the packaging box. Figure 2 and Figure 3 As shown, therefore, when the optical module is used in cross-medium applications, for example, when it is used in immersion liquid cooling applications, other media (such as liquid cooling media, etc.) can easily enter the optical channel between the optical fiber and the lens through the gap between the optical fiber array module and the packaging box. Due to the different refractive indices of other media, they will also interfere with the signal transmission between the optical fiber array module and the optical sub-module, which needs to be solved urgently. Utility Model Content

In this solution, by configuring the grooves arranged in an array, during assembly, it is only necessary to respectively arrange each optical fiber in each groove to ensure that each optical fiber is arranged in an array, which is not only convenient for assembly, but also can ensure assembly accuracy.

[0016] Preferably, the optical fiber array module includes four optical fibers, and the four optical fibers are arranged in an array.

By inserting the optical fiber array module into the first channel, the end of the optical fiber array module can be against the external window sill, and the gap between the optical fiber array module and the inner wall of the first channel is sealed by glue, which can effectively prevent other external media from entering the optical channel through the gap between the inner wall of the sleeve and the optical fiber array module, which is conducive to achieving a better sealing effect, thereby further improving the sealing performance of the joint between the external window sill and the optical fiber array module, so that the optical component can be effectively applied to cross-media applications and other occasions.

Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0041] Example 1

[0042] In this embodiment, an optical module applicable across media is provided, including a housing, an optical component, and an electronic submodule, etc., wherein the housing generally includes a base 11 and a cover plate, and the cover plate is detachably arranged on the base 11, so that an assembly space 12 for accommodating other devices can be formed between the cover plate and the base 11, and the optical component and the electronic submodule are arranged in the assembly space 12, such as Figure 8 shown.

[0043] In this embodiment, the optical component generally includes a fiber array module 2 and a packaging box 3, and an optical sub-module is arranged in the packaging box 3. During implementation, the optical sub-module in the optical component can generally include an optical transmitting sub-module or an optical receiving sub-module or an optical transmitting receiving sub-module, wherein the optical transmitting sub-module is mainly used to convert electrical signals into optical signals, and the optical receiving sub-module is mainly used to convert optical signals into electrical signals. The optical transmitting receiving sub-module can convert electrical signals into optical signals and optical signals into electrical signals. The electronic sub-module generally includes a circuit board and a chip. In the optical component, the optical sub-module is packaged in the packaging box 3, so that the optical sub-module can be packaged in a BOX manner using the packaging box 3, thereby effectively isolating the optical sub-module from the influence of other media. In the optical module, the optical submodule is usually electrically connected to the electronic submodule, and the optical submodule is usually connected to the fiber array module 2 in the optical component. The fiber array module 2 is connected to the fiber interface set in the shell through the optical fiber 21. In actual use, the signal generated in the optical module can be transmitted to the fiber interface via the fiber array module 2 and the optical fiber in turn, and transmitted out via the external optical fiber connected to the optical fiber interface, and the signal transmitted from the external optical fiber can be transmitted to the optical receiving submodule via the optical fiber interface, the optical fiber 21, and the fiber array module 2 in turn.

[0044] In this embodiment, the optical fiber array module 2 generally includes a first clamping plate 22, a second clamping plate 23 and an optical fiber 21. The optical fiber 21 is clamped between the first clamping plate 22 and the second clamping plate 23. In implementation, one end of the optical fiber is flush with one end of the first clamping plate 22 and the second clamping plate 23. The number of optical fibers in the optical fiber array module 2 can be determined according to actual needs. In implementation, the optical fiber array module generally includes at least two optical fibers, and each optical fiber is arranged in an array, such as Figure 4 As shown, an integrated optical fiber array module 2 is formed. As an example, in this embodiment, the optical fiber array module 2 includes four optical fibers 21, and the four optical fibers 21 are arranged in an array, such as Figure 4 shown.

[0045] In order to facilitate the fixing and assembly of the optical fiber array module 2, during implementation, the first clamping plate 22 is constructed with at least two grooves 221 for constraining the optical fiber 21, and each groove 221 is arranged in an array, and each optical fiber 21 is respectively arranged in each groove 221. The second clamping plate 23 is connected to the first clamping plate 22 and constrains the optical fiber 21 in the groove 221. In this embodiment, by configuring the grooves 221 arranged in an array, during assembly, it is only necessary to respectively arrange each optical fiber 21 in each groove 221 to ensure that each optical fiber 21 is arranged in an array, which is not only convenient for assembly, but also can ensure assembly accuracy. In specific implementation, the groove 221 can preferably use a V-groove, such as Figure 4 As shown, the groove 221 can be used to place the optical fiber 21 (including the shell and the core), or the core of the optical fiber 21, such as Figure 4 In implementation, the first clamping plate 22 and the second clamping plate 23 can be connected together by fasteners, or can be adhered together by glue 6. In implementation, the first clamping plate 22 and the second clamping plate 23 can preferably be glass plates.

[0046] In implementation, a light window 31 is formed on one side of the packaging box 3. Figure 5 and Figure 6 As shown, the optical fiber array module 2 can transmit signals with the optical sub-module in the packaging box 3 through the optical window 31. In the prior art, there are many implementations of the optical window 31. For example, in this embodiment, the optical window 31 includes an external window sill 32 arranged on the outside of the packaging box 3, an internal window sill 33 arranged on the inside of the packaging box 3, an optical channel 34 passing through the external window sill 32 and the internal window sill 33, and a lens 36 arranged in the optical channel 34. Figure 5 As shown, the outer window sill 32 faces the inner window sill 33, and the lens 36 can be installed in the light channel 34 through one side of the inner window sill 33, as shown in FIG. Figure 5 As shown, there is a distance between the lens 36 and the outer surface of the outer window sill 32. In this embodiment, the light channel 34 is constructed as a stepped structure to form a step 35, such as Figure 5 As shown, the lens 36 can be arranged at the step 35 of the optical channel 34, so that the lens 36 can be supported and restricted by the step 35, which not only facilitates the installation of the lens 36, but also helps the lens 36 to achieve a more secure installation effect. Since the optical fiber array module 2 usually has multiple optical fibers 21 arranged in an array, the entire optical fiber array module 2 has a flat structure. For example, the optical fiber array module 2 can be preferably constructed as a rectangular parallelepiped structure, such as Figure 4 Correspondingly, the optical channel 34 may also be preferably constructed as a flat structure, so as to effectively increase the width of the optical channel 34, so as to better adapt to the optical fiber array module 2.

[0047] During implementation, the shape of the packaging box 3 in the optical assembly can be determined according to actual needs. The packaging box 3 can generally be constructed as a square structure. For example, the packaging box 3 may include a box-like structure with an opening at the upper end, and a box cover 39 adapted to the box-like structure. The light window 31 is constructed on one side of the box-like structure, such as Figure 5 and Figure 6 As shown, the box cover 39 is sealed and connected to the top of the box-like structure and closes the opening, so that the box-like structure and the box cover 39 can together form a closed inner cavity, and the inner cavity is used to accommodate the optical sub-module to achieve the packaging of the optical sub-module. For another example, the packaging box 3 may include a box body 37, a connector 38 and a box cover 39, the connector 38 is connected to the box body 37, and the connector 38 and the box body 37 together form a box-like structure with an upper end opening, as shown in FIG. Figure 5 and Figure 6 As shown, the light window 31 can be constructed on the side wall of the other end of the box body 37. When assembled, the box cover 39 is sealed and connected to the top of the box body 37 and the connecting body 38, and closes the opening, so that the box body 37, the connecting body 38 and the box cover 39 can together form a closed inner cavity, and the inner cavity is used to accommodate the optical sub-module to achieve the packaging of the optical sub-module. Accordingly, the light window 31 is constructed on the side wall of the other end of the box body 37, as shown in FIG. Figure 5 and Figure 6 As shown, the internal optical submodule can transmit signals with the external optical fiber array module 2; in a further embodiment, the inner and outer sides of the connector 38 can also be respectively constructed with a plurality of steps 35, such as Figure 6 and Figure 8 As shown, the steps 35 are used to wire the inside of the packaging box 3 to achieve the connection between the optical submodule and the connector 38. Similarly, by constructing a plurality of steps 35 on the outside of the connector 38, it is convenient to wire the outside of the packaging box 3 through the steps 35 to achieve the connection between the connector 38 and the electronic submodule. A plurality of conductors are arranged between the inner step 35 and the outer step 35, so that the wiring and assembly operations can be performed conveniently on the basis of ensuring the packaging effect. In implementation, the box body 37 and the connector 38 can be an integrally formed component, or the box body 37 and the connector 38 can be manufactured separately, and then the connector 38 is installed on the box body 37, so that the connector 38 and the box body 37 together form a box-shaped structure with an upper end opening.

[0048] In the optical module provided in this embodiment, the end of the optical fiber array module 2 in the optical component faces the lens 364 of the light window, and the optical channel 34 between the optical fiber array module 2 and the lens 36 is filled with a refractive index matching glue 4, such as Figure 7 and Figure 8 As shown, the ends of each optical fiber 21 in the optical fiber array module 2 correspond to the filled refractive index matching glue 4 and also correspond to the lens 36, as shown in FIG. Figure 7 and Figure 8As shown, the optical path between the optical fiber and the lens is sealed by the filled refractive index matching glue. Specifically, in this embodiment, by filling the refractive index matching glue 4 in the optical channel 34 between the optical fiber array module 2 and the lens 36, and making the end of the optical fiber 21 correspond to the filled refractive index matching glue 4, the optical path of the optical fiber array module 2 and the optical sub-module in the packaging box 3 can be sealed by the filled refractive index matching glue 4. With such a design, on the one hand, the air in the optical channel 34 can be evacuated by the filled refractive index matching glue 4, thereby effectively reducing the influence of air on the optical path; on the other hand, the sealing of the optical path between the optical fiber array module 2 and the lens 36 can be effectively improved, so that in the occasion of cross-media application of the optical component and the optical module, other media are not easy to enter the optical channel 34, thereby effectively reducing the interference and influence of other media on signal transmission, making the optical module more stable and reliable, and also making the optical component and the corresponding optical module applicable to occasions such as cross-media application.

[0049] In addition, during implementation, the optical fiber array module 2 can be fixed to the packaging box 3 by the filled refractive index matching glue 4. During specific implementation, the optical fiber array module 2 can be directly fixed to the packaging box 3 by the filled refractive index matching glue 4 through reasonable size design and selection of different refractive index matching glues 4, so that there is no need to configure an additional bracket to fix the optical fiber array module 2, which is conducive to simplifying the structure and reducing costs; in addition, the effect of sealing and fixing the optical fiber array module 2 can be achieved at one time by filling the refractive index matching glue between the end of the optical fiber array module 2 and the lens 36, which not only makes the process simpler, but also makes the quality more guaranteed. In particular, when the optical window is configured with an external window sill 32, the length of the optical channel can be increased, which is conducive to more secure fixing of the optical fiber array module 2. During implementation, the number of optical components in the optical module can be determined according to actual needs, and one, two or more can be configured, and in the optical component, the number of optical fiber array modules 2 is adapted to the number of packaging boxes 3, for example, the number of optical fiber array modules 2 can be equal to the number of packaging boxes 3, and during implementation, the number of packaging boxes 3 is usually adapted to the number of modules configured by the optical sub-module. The arrangement of the optical components in the optical module can be determined according to actual needs. In a preferred embodiment, when at least two optical components are configured in the optical module, the packaging boxes 3 of the optical components can be overlapped, which is beneficial for saving space and facilitating the arrangement of the optical fibers 21. As an example, the optical module can include four optical components, and the optical fiber array modules 2 of each optical component are respectively configured with four optical fibers 21, such as Figure 4 and Figure 8As shown, at the same time, the packaging boxes 3 in two optical components respectively package light emitting sub-modules, and the packaging boxes 3 in the other two optical components respectively package light receiving sub-modules, the two packaging boxes for packaging light emitting sub-modules are arranged side by side, and the two packaging boxes 3 for packaging light receiving sub-modules are arranged side by side, and the packaging boxes 3 for packaging light emitting sub-modules and the packaging boxes 3 for packaging light receiving sub-modules are arranged overlapping, as shown in FIG. Figure 8 As shown, since the optical module is configured with four optical fiber array modules 2, and each optical fiber array module 2 is respectively configured with four optical fibers 21, sixteen optical fibers 21 can be formed, of which eight optical fibers 21 are respectively connected to the optical receiving sub-modules, and the other eight optical fibers 21 are respectively connected to the optical transmitting sub-modules, thereby realizing an 800G DR8 optical module, and the 800G DR8 optical module can be applied to cross-media applications and the like.

[0050] Example 2

[0051] Due to the different structures of the light window 31, the structure of the light module needs to be designed adaptively. In this embodiment, the light window 31 is not configured with an external window sill 32 and an internal window sill. Fig. 9 As shown, the end of the optical channel 34 is flush with the side wall of the packaging box 3. Similarly, based on the optical window 31 of this structure, in the optical module provided in this embodiment, the end of the optical fiber array module 2 in the optical component can correspond to the optical channel 34 at the side wall of the packaging box 3, and the optical fiber in the optical fiber array module 2 passes through the optical channel 34 to correspond to the lens 36 of the optical window 31, and the optical channel 34 between the optical fiber array module 2 and the lens 36 is filled with a refractive index matching glue 4, as shown in FIG. Fig.10 As shown, the filled refractive index matching glue 4 is used to achieve the light path sealing effect, so as to eliminate the air between the optical fiber array module 2 and the lens, and the refractive index matching glue 4 is used to prevent other external media from invading between the optical fiber array module 2 and the lens, thereby improving the transmission quality.

[0052] Similarly, the optical fiber array module 2 can be directly fixed to the packaging box 3 by using the filled refractive index matching glue 4, so there is no need to configure an additional bracket to fix the optical fiber array module 2, which is conducive to simplifying the structure and reducing costs.

[0053] Example 3

[0054] In order to solve the problem of improving the sealing between the optical fiber array module 2 and the external window sill 32, the main difference between the present embodiment 3 and the above-mentioned embodiment 1 is that in the optical module provided in the present embodiment, the optical module further includes a metal sleeve 5, such as Fig.11 As shown, one end of the metal sleeve 5 is configured with a first channel 51 adapted to the optical fiber array module 2, and the other end of the metal sleeve 5 is configured with a second channel 52 adapted to the external window sill 32. Fig.11As shown, the outer side of the end is structured with a circle of connecting pieces 53, as shown Fig.11 As shown, the first channel 51 is connected to the second channel 52. During assembly, the metal sleeve 5 can cover the external window sill 32, and the connecting piece 53 can be sealed to the side wall of the packaging box 3. For example, the sealed connection can be achieved by welding and applying sealant. At the same time, the optical fiber array module 2 can be inserted into the first channel 51 and can be sealed by glue 6.

[0055] Specifically, in this embodiment, sealing is achieved by welding one end of the metal sleeve 5 to the side wall of the packaging box 3 and filling a sealant between the metal sleeve 5 and the packaging box 3. The sealant may be a refractive index matching glue 4. The external window sill 32 is inserted into the second channel 52, so that the metal sleeve 5 can be used to cover the external window sill 32, thereby effectively improving the sealing between the external window sill 32 and the optical fiber array module 2. By inserting the optical fiber array module 2 into the first channel 51, the end of the optical fiber array module 2 can correspond to the optical channel in the external window sill 32, and the gap between the optical fiber array module 2 and the inner wall of the first channel 51 can be sealed by glue 6, as shown in FIG. Fig.11 As shown, other external media can be effectively prevented from entering the optical channel 34 through the gap between the inner wall of the sleeve and the optical fiber array module 2, which is conducive to achieving a better sealing effect, and further improves the sealing between the external window sill 32 and the optical fiber array module 2, so that the optical module can be effectively applied to cross-media applications and other occasions.

[0056] In a further embodiment, one side of the connecting piece 53 is further configured with a circle of bosses 54, such as Fig.12 As shown, the boss 54 is used to contact the side wall of the packaging box 3. During welding, the boss 54 can be used to contact the side wall of the packaging box 3. At this time, the other areas of the connecting piece 53 do not contact the side wall of the packaging box 3 and have a certain gap. Such a design is convenient for laser hot melt welding and laser penetration welding, and is conducive to achieving better welding effects. For example, during laser hot melt welding, the boss 54 can play a role similar to solder and be directly welded on the side wall of the packaging box 3. Since the boss 54 is an annular structure with a certain width, a relatively uniform weld can be formed along the circumferential direction of the optical channel 34, thereby effectively improving the connection effect between the metal sleeve 5 and the packaging box 3, and is conducive to achieving a better sealing effect through the sealant.

[0057] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
