[0002] In optical communication, optical modules are the core components for converting between photoelectric and optical signals. The transmitting end of an optical module converts electrical signals into optical signals and transmits them through optical fibers, while the receiving end converts the received optical signals back into electrical signals. Before leaving the factory, each optical module undergoes testing in high and low temperature environments (high temperature, room temperature, and / or low temperature) to verify its performance and ensure its operational stability and reliability.

It should be understood that the specific embodiments described in this specification are merely for explaining this application and are not intended to limit it.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] This application provides an optical module testing device that can provide high and low temperature environments such as high temperature, room temperature and / or low temperature for testing the optical module's working performance under the corresponding temperature environment.

[0035] For details, please refer to Figure 1-4An embodiment of this application provides an optical module testing device including a test housing 1, an electrical connector 2, a stage 3, a cover 4, and a sealing element 5. The test housing 1 includes a test circuit board 11 and a test shell 13. The test shell 13 has a test cavity 10, a insertion opening 101, and a first vent 102, with the insertion opening 101 and the first vent 102 respectively communicating with the test cavity 10. In this embodiment, the test shell 13 is disposed on the test circuit board 11, and the test shell 13 and the test circuit board 11 cooperate to form a relatively sealed test cavity 10. The electrical connector 2 is disposed within the test cavity 10 and electrically connected to the test circuit board 11. The electrical connector 2 is used to insert the optical module 6 to be tested, thereby electrically connecting the test circuit board 11 and the optical module 6 to be tested.

[0036] In this embodiment, a test optical cage 12 is also provided inside the test cavity 10. The test optical cage 12 is used to lock the optical module 6 under test. After the optical module 6 under test is inserted into the test optical cage 12 and connected to the electrical connector 2, it is electrically connected to the test circuit board 11 through the electrical connector 2 to simulate the working state of the optical module 6 under test in a corresponding temperature environment, thereby testing the performance of the optical module 6 under test. In some other embodiments, the optical cage may not be provided, and the optical module under test may be directly inserted into the test cavity 10 and connected to the electrical connector 2.

[0037] The stage 3 is connected to the test housing 1, and the cover 4 is used to cover the stage 3 to enclose and form an internal cavity 20. The cover 4 is rotatably connected to the stage 3 to close or open relative to the stage 3. Specifically, the optical module testing equipment has a first direction X, a second direction Y, and a third direction Z, and any two of the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In this embodiment, the stage 3 and the test housing 1 are arranged side by side along the first direction X, and the cover 4 covers the stage 3 along the third direction Z. The internal cavity 20 and the test cavity 10 are located on opposite sides of the insertion opening 101 in the first direction X.

[0038] A sealing element 5 is installed within the internal cavity 20 to form a module insertion / removal channel 30 within the internal cavity 20. One end of the module insertion / removal channel 30 communicates with the test cavity 10 through a insertion opening 101 and has an opening 40 facing the cover 4 to allow the optical module 6 to be tested to be inserted into or removed from the insertion opening 101 and the electrical connector 2. In this embodiment, the module insertion / removal channel 30 provides space for a single optical module 6 to be tested to be inserted into or removed from the insertion opening 101 along a first direction X. In some embodiments, the module insertion / removal channel can also be considered as a loading / unloading channel for the test equipment, and this loading / unloading channel can be sealed and opened.

[0039] In this embodiment, the width of the module insertion channel 30 in the second direction Y is greater than the width of a single optical module 6 under test, but less than twice the width of the optical module 6 under test. This ensures that the module insertion channel 30 has sufficient width in the second direction Y to allow the optical module 6 under test to be inserted into it. On the other hand, the width of the module insertion channel 30 in the second direction Y is not excessive, further ensuring that the module insertion channel 30 has a smaller internal space, keeping the amount of gas inside the channel at a lower level. This reduces the amount of gas that needs to be replaced during temperature switching, effectively improving ventilation efficiency and thus reducing the time required to switch the test environment temperature, thereby improving the testing efficiency of the optical module. In other embodiments, the width of the module insertion channel can also be appropriately expanded as needed.

[0040] In addition, the optical module testing equipment also includes a second vent 103, which is disposed on the stage 3 or the cover 4 and connected to the module insertion / removal channel 30. One of the first vent 102 and the second vent 103 is an air inlet, and the other is an air outlet, to create airflow within the module insertion / removal channel 30 and the test cavity 10. This airflow can have different temperatures; that is, by inputting gases of different temperatures, high-temperature airflow, room-temperature airflow, and / or low-temperature airflow can be formed within the module insertion / removal channel 30 and the test cavity 10, creating high and low temperature environments such as high temperature, room temperature, and / or low temperature, thereby testing the performance of the optical module operating under the corresponding temperature environments.

[0041] Specifically, during testing, the cover 4 must be closed to the platform 3 to seal the opening 40 of the module insertion / removal channel 30. At this time, the module insertion / removal channel 30, the insertion opening 101, and the test cavity 10 are sequentially connected to form a closed channel connecting the first vent 102 and the second vent 103. Furthermore, gas is introduced into the channel through one of the first vent 102 and the second vent 103, while gas is discharged through the other, to create an airflow within the module insertion / removal channel 30 and the test cavity 10. Before or after testing, the cover 4 can be opened to open the opening 40 of the module insertion / removal channel 30. At this time, the optical module 6 to be tested can be inserted or removed through this opening 40. That is, the optical module 6 to be tested can be inserted or removed through this opening 40 and inserted into the test cavity 10 through the insertion opening 101 to connect to the electrical connector 2 within the test cavity 10, or removed from the test cavity 10 through the insertion opening and the module insertion / removal channel 30.

[0042] The optical module testing equipment provided in this application embodiment has an internal cavity 20 and a test cavity 10. The internal cavity 20 and the test cavity 10 are connected through a plug-in opening 101 and cooperate to accommodate the optical module under test. Simultaneously, a sealing element 5 is provided within the internal cavity 20 to construct a narrow, sealable module insertion / removal channel 30. This module insertion / removal channel 30 connects to the test cavity through the plug-in opening 101, providing space for a single optical module under test to be inserted into or removed from the plug-in opening 101 and the test cavity 10. The test cavity 10 is connected to a first vent 102, and the module insertion / removal channel 30 is connected to a second vent 103, thereby forming an airflow channel. That is, the module insertion / removal channel 30, the plug-in opening, and the test cavity 10 are connected to form a relatively closed test channel and a fully enclosed airflow path. Moreover, the sealed module insertion / removal channel 30 can effectively prevent gas leakage from the loading and unloading points, thereby reducing energy waste and avoiding damage to testing personnel from leaked gas. In addition, the narrow module insertion channel 30 has a small internal space and a small amount of gas trapped inside. Therefore, when the ambient temperature inside the channel needs to be changed, the amount of gas that needs to be replaced is small, which can effectively improve the ventilation efficiency, thereby reducing the time for switching the test environment temperature and improving the testing efficiency of the optical module.

[0043] Please continue to refer to this. Figure 1-4 In one embodiment, the second vent 103 is disposed at one end of the module insertion / removal channel 30 opposite to the insertion opening 101 in the first direction X, and the first vent 102 is disposed at one end of the test cavity 10 opposite to the insertion opening 101 in the first direction X. For details, please refer to... Figure 5 and 6 In this embodiment, the test cavity 10 includes a first sub-cavity 104 and a second sub-cavity 105 that are interconnected. The first sub-cavity 104 extends along a first direction X and communicates with the insertion opening 101, and the test optical cage 12 is disposed in the first sub-cavity 104. The second sub-cavity 105 is connected to the end of the first sub-cavity 104 away from the module insertion channel 30. In this embodiment, the second sub-cavity 105 extends along a second direction Y, a first vent 102 is located at the end of the second sub-cavity 105 away from the first sub-cavity 104, and a second vent 103 is disposed on the stage 3.

[0044] In some other embodiments, the second vent 102 may also be disposed on the cover 4. Alternatively, the test cavity 10 may only include a first sub-cavity 104 extending along the first direction X, with the first vent 102 disposed at the end of the first sub-cavity 104 away from the insertion opening 101. Alternatively, the first vent 102 may also be disposed on the side wall of the test cavity 10, and located on the side of the electrical connector 2 opposite to the insertion opening 101.

[0045] Please continue to refer to this. Figure 1-4In one embodiment, the stage 3 includes a support portion 301 and a connecting portion 302. The connecting portion 302 is connected to the side of the support portion 301 near the test cavity 10 and intersects with the support portion 301. The test housing 1 is connected to the side of the connecting portion 302 facing away from the support portion 301. The connecting portion 302 is provided with a first notch 3021, which extends through the connecting portion 302 along a first direction X, and the aforementioned insertion opening 101 is provided within the first notch.

[0046] The sealing element 5 includes a first sealing gasket 51, which is disposed on the platform 3. The first sealing gasket 51 includes a first sealing portion 511 and a second sealing portion 512. The first sealing portion 511 is laid on the support portion 301, and the second sealing portion 512 is laid on the connecting portion 302. The second sealing portion 512 is used to seal the connection end between the cover 4 and the platform 3. In this embodiment, the connection end between the cover 4 and the platform 3 refers to the part where the cover 4 and the platform 3 are rotatably connected. This connection end includes the end of the cover 4 near the connecting portion 302 and the end of the connecting portion 302 away from the test chamber 1. The second sealing portion 512 extends in the third direction Z. When the cover 4 and the platform 3 are closed, the second sealing portion 512 is sandwiched between the end of the cover 4 facing the connecting portion 302 and the connecting portion 302 to seal the connection between the cover 4 and the connecting portion 302.

[0047] In this embodiment, the second sealing part 512 has a second notch 5121, and the first notch 3021 is opposite to and communicates with the second notch 5121. The first notch 3021 and the second notch 5121 cooperate to form an insertion opening 101. The first sealing part 511 has a first through groove 5111 extending along the first direction X. One end of the first through groove 5111 is connected to the first notch 3021 via the second notch 5121. The first through groove 5111, the first notch 3021, and the second notch 5121 cooperate to form a module insertion channel 30. The groove of the first through groove 5111 facing the cover 4 forms the opening 40 of the module insertion channel 30.

[0048] Furthermore, the first through groove 5111 penetrates the first sealing portion 511 in a third direction Z. The supporting portion 301, the first through groove 5111, the first notch 3021, and the second notch 5121 cooperate to form the module insertion and removal channel 30. Even further, the supporting portion 301 has a second through groove 3011 on its surface facing the first sealing portion 511. The second through groove 3011 is opposite to and communicates with the first through groove 5111, that is, the first through groove 5111, the second through groove 3011, the first notch 3021, and the second notch 5121 cooperate to form the module insertion and removal channel 30. Here, the second through groove 3011 of the supporting portion 301 is a groove with a bottom, the opening of the groove facing the first through groove 5111, so that the first through groove 5111 and the second through groove 3011 are connected to form a deeper groove, and one end of the deeper groove is connected to the first notch 3021 and the second notch 5121. In this embodiment, the shape and size of the opening of the second through groove 3011 are approximately the same as the shape and size of the opening of the first through groove 5111.

[0049] In some other embodiments, the surface of the support portion 301 facing the first sealing portion 511 may not have the second through groove 3011, that is, the surface of the support portion 301 is a plane. In this way, the support portion 301, the first through groove 5111, the first notch 3021 and the second notch 5121 cooperate to form the module insertion and removal channel 30.

[0050] Of course, in other embodiments of this application, the first through groove 5111 may not penetrate the first sealing part 511, that is, a groove with a bottom is formed on the first sealing part 511, and one end of the groove is connected to the first notch 3021 and the second notch 5121. In this way, the first through groove 5111, the first notch 3021 and the second notch 5121 cooperate to form the module insertion and removal channel 30.

[0051] In one embodiment, the cover 4 includes a cover body 41 and a cover peripheral sidewall 42. The cover peripheral sidewall 42 is connected to the outer edge of the cover body 41 and surrounds the cover body 41. One end of the cover body 41 is rotatably connected to the connecting part 302 of the platform 3, realizing a rotatable connection between the cover 4 and the platform 3.

[0052] When the cover 4 is closed with the platform 3, the cover body 41 and the support part 301 are positioned opposite each other, the cover peripheral sidewall 42 surrounds the support part 301, the connecting part 302 is located at the end of the cover body 41, and the sealing element 5 is sandwiched between the cover body 41 and the support part 301, and / or between the cover body 41 and the connecting part 302, and / or between the cover peripheral sidewall 42 and the support part 301. Specifically, a portion of the first sealing part 511 of the first sealing gasket 51 is sandwiched between the cover body 41 and the support part 301, and a portion of the first sealing part 511 away from the test chamber 1 is sandwiched between the cover peripheral sidewall 42 and the support part 301. At the connection end between the cover 4 and the platform 3, a portion of the second sealing part 512 is sandwiched between the cover body 41 and the connecting part 302, and another portion of the second sealing part 512 is sandwiched between the cover peripheral sidewall 42 and the connecting part 302, thus ensuring the sealing effect of the module insertion and removal channel 30.

[0053] In one embodiment, the seal 5 further includes a second sealing gasket 52, which is embedded in the side of the cover 4 facing the platform 3, and is used to seal the opening 40 of the module insertion / removal channel 30 when the cover 4 closes the platform 3. In this embodiment, the module insertion / removal channel 30 is sealed by the cooperation of the first sealing gasket 51 and the second sealing gasket 52, thus effectively preventing gas leakage from the module insertion / removal channel 30, thereby reducing energy waste and avoiding damage to test personnel from leaked gas.

[0054] In this embodiment, a third through groove 5211 corresponding to the first through groove 5111 is formed on the surface of the second sealing gasket 52 facing the first sealing gasket 51. The third through groove 5211 is used to avoid the optical module 6 to be tested when the cover 4 and the platform 3 are closed. The first through groove 5111 and the third through groove 5211 cooperate to form a space to accommodate the optical module 6 to be tested. That is, the depth of the first through groove 5111 is relatively shallow, so when the optical module 6 to be tested is inserted, it will not be completely submerged in the first through groove 5111, but will be partially above the first through groove 5111, thereby facilitating the removal of the optical module 6 to be tested.

[0055] Furthermore, the second sealing gasket 52 includes a sealing body 521 and a sealing peripheral wall 522. The sealing peripheral wall 522 is connected to the outer edge of the sealing body 521 and surrounds the sealing body 521. When the cover 4 is closed with the platform 3, the sealing body 521 is positioned opposite to the first sealing part 511, and the sealing peripheral wall 522 surrounds the first sealing part 511 to seal the internal cavity 20, thereby achieving the sealing of the module insertion and removal channel 30. The third through groove 5211 is located on the sealing body 521; specifically, the third through groove 5211 is formed on the surface of the sealing body 521 facing the first sealing part 511.

[0056] Please refer to Figure 1 and 2In one embodiment, the first sealing gasket 51 is further provided with an optical fiber groove 5112, which is used to accommodate a test optical fiber patch cord. One end of the optical fiber groove 5112 is connected to the module insertion channel 30, and the other end is configured to allow the test optical fiber patch cord to extend to the outside of the cover 4. When the cover 4 is closed with the stage 3, the cover 4 or the second sealing gasket 52 is also used to seal the optical fiber groove 5112.

[0057] Specifically, the optical module testing equipment also includes an optical fiber sealing structure 8. The optical fiber sealing structure 8 is disposed on the support portion 301 of the stage 3, and at least a portion of the optical fiber sealing structure 8 is located in the optical fiber groove 5112. The test optical fiber patch cord passes through the optical fiber sealing structure 8, and a sealed connection is established between the test optical fiber patch cord and the optical fiber sealing structure 8. When the cover 4 is closed to the stage 3, the first sealing gasket 51 and the second sealing gasket 52 cooperate to seal the optical fiber groove 5112, and a sealed connection is established between the test optical fiber patch cord and the optical fiber sealing structure 8. This achieves a sealed exit of the test optical fiber patch cord, further ensuring a complete seal at the loading and unloading points, effectively preventing gas leakage from the loading and unloading points, thereby reducing energy waste and avoiding injury to testing personnel.

[0058] In one embodiment, the optical module testing equipment further includes a latch 7. The latch 7 is disposed on the cover 4 and / or the platform 3, and is used to lock the cover 4 and the platform 3 so that they are tightly closed, thereby ensuring that the seal 5 reliably seals the module insertion and removal channel 30, thereby effectively preventing gas leakage, reducing energy waste, and avoiding injury to testing personnel. Figure 2 An example is shown where the latch 7 is provided on the cover 4, specifically on the cover periphery sidewall 42 of the cover 4 away from the connecting part.

[0059] Please refer to the following: Figure 7 , Figure 7 This is a schematic diagram of the structure of the second embodiment of the optical module testing equipment of this application. Figure 1-6 In the illustrated embodiments, the optical module testing equipment has only one module insertion / removal channel 30 and one insertion opening 101, thus constructing only one testing channel. This differs from the embodiments described above. Figure 7 In the embodiment shown, the optical module testing equipment is provided with multiple module insertion / removal channels 30. Other structures of this embodiment can be referred to the above embodiments, and will not be described again here.

[0060] Specifically, in this embodiment, there are multiple module insertion / removal channels 30, which are spaced apart and isolated from each other in the second direction Y. There are also multiple second vents 103, with each module insertion / removal channel 30 having a second vent 103 connected to it. Correspondingly, there are also multiple insertion openings 101, each corresponding to a module insertion / removal channel 30. Each module insertion / removal channel 30 is connected to the test cavity 10 through a corresponding insertion opening 101, and each module insertion / removal channel 30 and the test cavity 10 are located on opposite sides of the corresponding insertion opening 101 in the first direction X. In this embodiment, there are also multiple test cavities 10, each corresponding to a module insertion / removal channel 30. Each test cavity 10 contains a corresponding test optical cage 12, allowing the optical module 6 to be tested in each module insertion / removal channel 30 to be inserted into the corresponding test optical cage 12 for testing. This embodiment, by setting up multiple module plug-in channels 30 and multiple test optical cages 12, enables the optical module testing equipment to perform testing on multiple optical modules simultaneously, which helps to improve the testing efficiency of the optical module testing equipment. Furthermore, the plug-in channels are isolated from each other, reducing temperature interference between adjacent channels.

[0061] Please refer to the following: Figure 8 , Figure 8 This is a structural schematic diagram of the third embodiment of the optical module testing equipment of this application.

[0062] With the above Figure 7 The difference in the embodiment shown is that in this embodiment, there is one test cavity 10, and multiple test optical cages 12 are provided in the test cavity 10. The test optical cages 12 correspond one-to-one with the module insertion and removal channels 30, so that the optical module 6 to be tested in each module insertion and removal channel 30 can be inserted into the corresponding test optical cage 12 for testing.

[0063] In summary, this application provides an optical module testing device. This device has an internal cavity and a test cavity, which are connected by a plug-in opening and cooperate to accommodate an optical module. A seal is installed within the internal cavity to construct a narrow, sealable module insertion / removal channel. This channel connects to the test cavity via the plug-in opening, providing space for inserting or removing a single optical module under test from both the plug-in opening and the test cavity. The test cavity connects to a first vent, and the module insertion / removal channel connects to a second vent, thus forming a relatively sealed airflow channel. The sealed module insertion / removal channel effectively prevents gas leakage from the loading and unloading points, thereby reducing energy waste and preventing injury to testing personnel. Furthermore, the narrow module insertion / removal channel has a small internal space, resulting in less gas retention. Therefore, less gas needs to be replaced during temperature changes, effectively improving ventilation efficiency and reducing the time required to switch test environment temperatures, thus increasing the testing efficiency of the optical module.

[0064] The above steps are provided only to help understand the method, structure, and core ideas of this application. Those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
