[0028] It is to be understood that the application can assume various alternative forms of embodiment, and it is not to be limited to the embodiments set forth and described herein. Rather, the instant disclosure is intended to cover all adaptations, modifications, and equivalents. In addition, unless expressly stated otherwise, the description of an embodiment should not be construed as indicating that the features, items or components relating thereto are essential or indispensable. In the drawings, the size and relative sizes of layers and regions can be exaggerated for clarity.

[0029] It will be understood that when an element or layer is referred to as being "on" or "connected to" another element or layer, it can be directly on or connected to the other element or layer or intervening elements or layers can be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element or layer, there are no intervening elements or layers present. It will also be understood that, although the terms first, second, third, etc. can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms since such terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section.

[0030] Spatially relative terms, such as "beneath", "below", "lower", "under", "above", "upper" and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The first output end of the control module 1 sends a switch control instruction to the controlled end of the switch module 5. After receiving the instruction, the switch module 5 opens the switch. 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 through the output end of the voltage stabilizing source module 3 to the input end of the switch module 5. The first output end of the switch module 5 outputs a stable voltage of 54V to the first voltage and current detection module 9.

The voltage signal is transmitted to the second voltage and current detection module 11 through the second network transformer module 15. The second voltage and current detection module 11 transmits the voltage signal to the test load module through the second output end of the switch module 5, forming a loop. The second voltage and current detection module 11 is used to detect the voltage signal output by the power supply end (PSE) of the FTTR intelligent networking product. The voltage values and current values detected by the first voltage and current detection module 9 and the second voltage and current detection module 11 are transmitted to the control module 1.
