On the contrary, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the drawings, for clarity, the dimensions and relative dimensions of layers and regions may be exaggerated. The same reference numerals throughout the drawings denote the same elements.

[0021] It should be understood that when an element or layer is referred to as being "on", "adjacent to", "connected to" or "coupled to" another element or layer, it can be directly on, adjacent to, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being "directly on", "directly adjacent to", "directly connected to" or "directly coupled to" another element or layer, there are no intervening elements or layers. It should be understood that although the terms first, second, third, etc. may be used to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part.

The first output end of the control module 1 is connected to the control end of the first switch module 5, the input end of the voltage regulator module 3 and the control end of the second switch module 7. The output end of the voltage regulator module 3 is connected to the input end of the first switch module 5; The output end of the first switch module 5 is connected to the input end of the first voltage and current detection module 9. The second output end of the first voltage and current detection module 9 is connected to the first end of the first network transformer module 15. The second end of the first network transformer module 15 is connected to the power supply end 19 of the test circuit. The input end of the second switch module 7 is connected to the second output end of the second voltage and current detection module 11. The output end of the second switch module 7 is connected to one end of the test load module 13. The other end of the test load module 13 is connected to the power supply end of the whole-house fiber optic intelligent networking product; The input end of the second voltage and current detection module 11 is connected to the second end of the second network transformer module 17. The first end of the second network transformer module 17 is connected to the power receiving end 21 of the test circuit; The control module 1 is used to obtain the first voltage value and the first current value detected by the first voltage and current detection module 9 and the second voltage value and the second current value detected by the second voltage and current detection module 11, calculate the first voltage difference according to the first voltage value and the second voltage value respectively, calculate the first current difference according to the first current value and the second current value, and determine whether the whole-house fiber optic intelligent networking product is abnormal according to the first voltage difference and the first current difference.

[0026] Among them, the power supply end (PSE) 19 of the test circuit is used to connect to the power receiving end (PD) of the whole-house fiber optic (FTTR) intelligent networking product, and the power receiving end (PD) 21 of the test circuit is used to connect to the power supply end (PSE) of the whole-house fiber optic (FTTR) intelligent networking product.

[0027] The working process of the above test circuit is as follows: Connect the whole-house fiber optic (FTTR) intelligent networking product to the test circuit through the power supply end (PSE) 19 and the power receiving end 21 of the test circuit. The first output end of the control module 1 sends a switch control instruction to the controlled end of the first switch module 5. After receiving the instruction, the first switch module 5 turns on. At the same time, the first output end of the control module 1 sends a power supply control instruction to the voltage stabilizing source module 3. After receiving the instruction, the voltage stabilizing source module 3 outputs a stable voltage of about 54V, which is output to the input end of the first switch module 5 through the output end of the voltage stabilizing source module 3. The output end of the first switch module 5 outputs a stable voltage of 54V to the first voltage and current detection module 9. The first output end of the first voltage and current detection module 9 transmits the 54V voltage to the first network transformer module 15. After processing the 54V voltage, the first network transformer module 15 supplies power to the power receiving end (PD) of the whole-house fiber optic (FTTR) intelligent networking product through the power supply end (PSE) 19 of the test circuit, and transmits the detected first voltage value and first current value to the control module 1 through the second output end of the first voltage and current detection module 9; When powering the power - receiving end (PD) of the full - house fiber - to - the - room (FTTR) intelligent networking product through the power - supply end (PSE) 19 of the test circuit, the power - supply end (PSE) of the full - house fiber - to - the - room (FTTR) intelligent networking product is turned on. Since the test load module 13 is connected to the power - supply end (PSE) of the full - house fiber - to - the - room (FTTR) intelligent networking product, the full - house fiber - to - the - room (FTTR) intelligent networking product drives the test load module 13. The power - supply end (PSE) of the full - house fiber - to - the - room (FTTR) intelligent networking product outputs a signal to the power - receiving end (PD) 21 of the test circuit, and then transmits the signal to the second voltage - current detection module 11 through the second network transformer module 17. The second voltage - current detection module 11 connects the signal to the test load module 13 through the second output end of the second switch module 7 to form a loop. The second voltage - current detection module 11 is used to detect the signal output by the power - supply end (PSE) of the full - house fiber - to - the - room (FTTR) intelligent networking product, and the second voltage - current detection module 11 transmits the detected second voltage value and second current value to the control module 1; The control module 1 receives the first voltage value and first current value detected by the first voltage - current detection module 9, and the second voltage value and second current value detected by the second voltage - current detection module 11. It respectively subtracts the first voltage value from the second voltage value to obtain a first voltage difference, and subtracts the first current value from the second current value to obtain a first current difference. By judging whether the first voltage difference and the first current difference are within the preset range of 5%, it is determined whether the full - house fiber - to - the - room (FTTR) intelligent networking product is a qualified product.

[0028] In this embodiment, by setting the first voltage - current detection module and the second voltage - current detection module, the voltage and current of the power - supply end and the power - receiving end of the full - house fiber intelligent networking product are detected in real - time. The power - supply end and the power - receiving end can be detected simultaneously, improving the detection efficiency. By the control module respectively subtracting the voltage values and current values of the power - supply end and the power - receiving end of the full - house fiber intelligent networking product, and judging whether the full - house fiber intelligent networking product is a qualified product according to the differences of the voltage values and current values, the detection accuracy is improved.

The control module 1 obtains the first voltage value and the first current value of the first power receiving end of the full-house fiber (FTTR) intelligent networking product through the first voltage and current detection module 9, and obtains the second voltage value and the second current value of the power supply terminal of the full-house fiber (FTTR) intelligent networking product through the second voltage and current detection module 11. The first voltage value and the second voltage value are subtracted to obtain a first difference, and the first current value and the second current value are subtracted to obtain a second difference. It is judged whether the first difference and the second difference meet the preset range. When the preset range is satisfied, return. The control module 1 turns on the third switching tube 503 to supply power to the second power receiving end of the full-house fiber (FTTR) intelligent networking product.
