[0032] In one embodiment, such as Figure 1 As shown, an FTTR-B product testing device 100 is disclosed, which includes a main control module 110 and a switching module 120;

[0033] The first end of the switching module 120 is used to connect at least two devices under test 200, and the second end of the switching module 120 is connected to the first end of the main control module 110.

[0034] The second end of the main control module 110 is used to connect to the external test equipment 300;

[0035] When the test command output by the external test device 300 is sent to the main control module 110, the main control module 110 performs a test on the device under test 200.

[0036] In this embodiment, the testing equipment can be a companion device.

[0037] In this embodiment, when the FTTR-B product testing equipment 100 receives a test command from the external testing equipment 300, it acquires the device information of each device under test 200, determines the test result of the device under test 200 based on the device information, and returns the test structure to the external testing equipment 300. When the test result indicates that the device under test 200 does not meet the production requirements, it updates the devices under test 200 connected to the FTTR-B product testing equipment 100 and continues to test the new devices under test 200.

[0038] In this specific implementation, when the main control module 110 receives the test command output by the external test device 300, it responds to the test command, obtains the device information of each device under test 200, determines the test result of the device under test 200 based on the device information, and returns the test result to the external test device 300. The device information includes the current voltage and current values ​​of the device under test 200. It determines whether the voltage value is within a preset voltage range and whether the current value is within a preset current range. If both the voltage and current values ​​are within the voltage and current ranges, the device under test 200 is determined to meet production requirements. If either the voltage or current value is outside the voltage or current range, the device under test 200 is determined to not meet production requirements. The main control module 110 can be a main control chip, and the type of main control chip includes, but is not limited to, Field Programmable Gate Arrays (FPGAs) and Microprocessors (MPUs), etc., which are not limited in this embodiment. The switching module 120 is an integrated circuit responsible for forwarding device information between the device under test 200 and the main control module 110, such as a switch chip.

[0039] In summary, this utility model discloses an FTTR-B product testing device 100, including a main control module 110 and a switching module 120. The first end of the switching module 120 is used to connect at least two devices under test (DUTs) 200, and the second end of the switching module 120 is connected to the first end of the main control module 110. The second end of the main control module 110 is used to connect to an external testing device 300. When the external testing device 300 outputs a test command to the main control module 110, the main control module 110 tests the DUTs 200. Therefore, in this utility model, the DUTs 200 are connected to the main control module 110 through the switching module 120. When the switching module 120 is connected to at least two DUTs 200, the switching module 120 only occupies one interface of the main control module 110, thus avoiding the problem of limited interfaces of the main control module 110. Compared with the prior art, this increases the number of DUTs 200 that the testing device can connect to simultaneously, achieving the goal of improving the testing efficiency of the testing device.

[0040] In one embodiment, such as Figure 2 As shown, the switching module 120 includes at least two switching sub-modules 121. The first end of the switching sub-module 121 is used to connect at least two devices under test 200, and the second end of the switching sub-module 121 is connected to the first end of the main control module 110.

[0041] It is understandable that when each switching submodule 121 connects to at least two devices under test (DUTs) 200, the more switching submodules 121 connected to the main control module 110, the more DUTs 200 can ultimately be connected in parallel by the FTTR-B product test equipment 100 in this embodiment. In this embodiment, the switching submodules 121 can be connected to the main control module 110 via the IIC bus. Therefore, by increasing the number of switching submodules 121 in this embodiment, the maximum number of DUTs 200 that can be connected in parallel by the FTTR-B product test equipment 100 can be further increased, thereby further improving the testing efficiency of the FTTR-B product test equipment 100.

[0042] In one embodiment, the switching submodule 121 includes at least two test interfaces, through which the switching submodule 121 connects to the device under test 200. The test interfaces include, but are not limited to, RJ45 interfaces. The maximum number of devices under test 200 that the FTTR-B product test equipment 100 can test in parallel corresponds to the number of test interfaces.

[0043] In one embodiment, such as Figure 3 As shown, the FTTR-B product testing equipment 100 in this embodiment also includes a testing module 130. The first end of the testing module 130 is connected to the second end of the switching module 120, and the second end of the testing module 130 is connected to the first end of the main control module 110.

[0044] In a specific implementation, when the main control module 110 receives the test instruction transmitted from the external test device 300, it sends an enable instruction to the test module 130. The test module 130 responds to the enable instruction, obtains the device information of each device under test 200, determines the test result of the device under test 200 based on the device information, and returns the test result to the external test device 300.

[0045] In summary, by establishing a separate test module 130 in this embodiment, the computational load of the main control module 110 can be reduced, which is beneficial to improving the stability of the FTTR-B product testing equipment 100.

[0046] In one embodiment, the test module 130 in this embodiment includes at least two test sub-modules 131. The first end of the test sub-module 131 is connected to the second end of the switching module 120, and the second end of the test sub-module 131 is connected to the first end of the main control module 110.

[0047] Understandably, when the test module 130 acquires device information from multiple devices under test 200 simultaneously, it can typically only process the device information one by one to test the devices under test 200. However, when the test module 130 includes at least two test sub-modules 131, the more test sub-modules 131 there are, the more device information can be processed in parallel, enabling parallel testing of the devices under test 200. Therefore, the more test sub-modules 131 there are, up to the maximum number of devices under test 200 that can be connected to the FTTR-B product test equipment 100, the more effectively the testing efficiency of the FTTR-B product test equipment 100 can be improved. The test module 130 and test sub-modules 131 can be software functional modules of the main control module 110 or independent hardware modules; this embodiment does not impose any limitations.

[0048] In one embodiment, such as Figure 4 As shown, the FTTR-B product testing equipment 100 in this embodiment also includes a first power supply module 140. The first end of the first power supply module 140 is used to connect to the first power supply 400, and the second end of the first power supply module 140 is used to supply power to the device under test 200.

[0049] The first power supply 400 is a DC power supply. The voltage of the first power supply 400 can be 12A and the current can be 20A, which is not limited in this embodiment.

[0050] In a specific implementation, the first power supply module 140 in this embodiment may include at least two power supply interfaces, through which the first power supply module 140 supplies power to each device under test 200. The power supply interfaces may be DC interfaces.

[0051] In one embodiment, such as Figure 5 As shown, the FTTR-B product testing equipment 100 in this embodiment also includes a second power supply module 150. The first end of the second power supply module 150 is used to connect to the second power supply 500, and the second end of the second power supply module 150 is used to connect to the power supply terminals of the main control module 110 and the switching module 120.

[0052] In one embodiment, the second power supply module 150 includes a voltage regulator module 151. The first end of the voltage regulator module 151 is used to connect to the second power supply 500, and the second end of the voltage regulator module 151 is used to connect to the power supply terminals of the main control module 110 and the switching module 120.

[0053] The voltage regulator module 151 is used to provide a stable voltage to the main control module 110 and the switching module 120, and to provide safety protection for the FTTR-B product test equipment 100, such as overvoltage protection and overcurrent protection.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
