With the widespread application of F5G and WiFi 6 / 7 in campuses, homes and other scenarios, the demand for hot application scenarios such as all-optical campuses and all-optical homes is becoming increasingly popular, and the demand for scenarios that introduce low-power terminals (rated voltage ≤48V, power ≤100W) such as fiber to the desktop, fiber to the camera, and fiber to the access point (AP) is also emerging in an endless stream.

[0003] In response to this demand, the existing patent application with publication number CN221200008U proposes an optoelectronic hybrid connector, which adopts a two-conductive pin design and integrates the dual functions of optical fiber communication and power transmission.

At present, the FTTR-B master and slave devices are connected to each other through optoelectronic hybrid connectors.

[0025] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0026] Example 1

[0027] like Figure 1As shown, the optoelectronic hybrid connector test system includes an optoelectronic hybrid connector to be tested, an insertion loss tester, an electrical conductor device and a power supply device. The first end of the optoelectronic hybrid connector to be tested includes an electrical interface and a first optical fiber interface, the electrical interface includes a conductive metal copper sheet, the conductive metal copper sheet and the insertion loss tester are both connected to the power supply device, and the electrical interface of the optoelectronic hybrid connector to be tested is connected to the power supply device via an optoelectronic hybrid cable, and the electrical connection part in the optoelectronic hybrid cable is used to transmit electrical signals to the optoelectronic hybrid connector to be tested. The first optical fiber interface is connected to the first terminal of the standard optical fiber, the second terminal of the standard optical fiber is connected to the reference end of the insertion loss tester, the second end of the optoelectronic hybrid connector to be tested is connected to the first optoelectronic terminal of the optoelectronic hybrid cable, and the second optoelectronic terminal of the optoelectronic hybrid cable is connected to the measuring end of the insertion loss tester or the electrical conductor device. In order to reflect that the second optoelectronic terminal of the optoelectronic hybrid cable can be connected to both the measuring end of the insertion loss tester and the electrical conductor device, Figure 1 The optical / electrical hybrid cable between the optical / electrical hybrid connector to be tested and the electrical conductor device is indicated by a dotted line.

[0028] The electrical conductor device can be not only electrical performance test equipment such as ammeters, voltmeters, oscilloscopes, etc., but also any device that can detect and display the characteristics of electrical signals. In addition, the device has an intelligent notification function, which can instantly provide testers with feedback on the current circuit conduction status in the form of sound, light, electricity, etc., thereby improving the intuitiveness and convenience of the test. In addition, if Figure 2 As shown, the first optoelectronic terminal and the second optoelectronic terminal can both be optoelectronic hybrid connector plugs.

[0029] Specifically, when the optical performance test is performed on the optical hybrid connector to be tested, the second optical connector of the optical hybrid cable is connected to the measuring end of the insertion loss tester. At this time, the optical hybrid connector to be tested, the standard optical fiber, the insertion loss tester and the optical hybrid cable constitute an optical performance test loop. During the formal test, the light source (such as a laser) inside the insertion loss tester sends an optical signal of known intensity and wavelength to the reference end. The optical signal is transmitted to the first optical fiber interface of the optical hybrid connector through the standard optical fiber, and then enters the optical hybrid cable through the optical path of the optical hybrid connector. After the optical signal is transmitted in the optical hybrid cable, it is received by the second optical connector and returned to the measuring end of the insertion loss tester. The insertion loss tester compares the optical signal received at the measuring end with the original transmitted signal to calculate the insertion loss, that is, the energy loss of the signal during the transmission process, and the return loss, that is, the degree to which the signal is reflected back to the source end at the connector. The insertion loss and return loss parameters reflect the optical performance of the optical hybrid connector. After the test is completed, the insertion loss tester will display the values ​​of the insertion loss and return loss, as well as possible spectrum diagrams or waveform diagrams, to help testers intuitively understand the performance of the optical hybrid connector. Finally, the test results are compared with preset performance indicators or standards to determine whether the optical performance of the optoelectronic hybrid connector to be tested is qualified.

[0030] Furthermore, the first terminal of the standard optical fiber can be a UPC plug, and the second terminal of the standard optical fiber can be an APC plug. The UPC plug is a type of end face grinding method for an optical fiber connector, and its characteristic is that the end face is specially ground to form a slight arc to achieve more precise docking. This grinding method optimizes the end face polishing and surface finish, so that the optical fiber end face can be better in contact, reducing the air gap, thereby reducing the insertion loss. The APC plug is another type of end face grinding method for an optical fiber connector, and its characteristic is that the optical fiber end face is ground into an 8° bevel. This bevel design not only allows the optical fiber end face to be in closer contact, but also reflects the light into the cladding through its bevel angle instead of returning directly to the light source, thereby providing better connection performance and higher return loss performance. The optoelectronic hybrid connector test system of this embodiment uses UPC plugs and APC plugs as the terminal heads of the standard optical fiber, which can significantly improve the accuracy and flexibility of the optoelectronic hybrid connector test system, thereby being able to more accurately judge the performance of the optoelectronic hybrid connector.

[0031] In addition, in order to improve the reliability of the optoelectronic hybrid connector test system, the optoelectronic hybrid connector test system also includes a calibration device, and the calibration device is connected to the insertion-return loss tester. Before the optical performance test of the optoelectronic hybrid connector to be tested is performed, the insertion-return loss tester can be calibrated using the calibration device. Preferably, the calibration device includes at least one of a light source module calibration component, a power module calibration component, and a return loss module calibration component. For example, the light source module calibration component may include an optical power meter, the power module calibration component may include a light source and an optical attenuator, and the return loss module calibration component may include a return loss calibration optical fiber.

[0032] When the electrical performance test is performed on the optoelectronic hybrid connector to be tested, the second optoelectronic terminal of the optoelectronic hybrid cable is switched to the electrical conductor device. At this time, the power supply device, the optoelectronic hybrid connector to be tested and the electrical conductor device constitute a complete electrical performance test circuit. Specifically, a conductive metal copper sheet is provided inside the optoelectronic hybrid connector to be tested. One end of the conductive metal copper sheet is connected to the power supply device as an electrical interface, and the other end is connected to the optoelectronic hybrid cable to form an electrical path. After the power supply device is started, the current passes through the electrical interface of the optoelectronic hybrid connector to be tested and the optoelectronic hybrid cable to reach the electrical conductor device. The electrical conductor device measures and displays the received current, etc., to provide intuitive and accurate test results for the tester.

[0033] Furthermore, if Figure 2 As shown, the power supply device is an optical socket. The optical socket has its own power supply. At this time, the electrical interface of the optoelectronic hybrid connector to be tested and the insertion loss tester can be connected to the optical socket through an optoelectronic hybrid cable. In particular, when two conductive metal copper sheets are provided inside the optoelectronic hybrid connector to be tested, the first ends of the two conductive metal copper sheets are connected to the optical socket as different electrical interfaces, and the second ends are respectively connected to the first optoelectronic terminal of the optoelectronic hybrid cable, thereby forming two electrical performance test circuits. At this time, the optoelectronic hybrid cable connected to the optical socket provides two electrical signals to the two conductive metal copper sheets in the optoelectronic hybrid connector to be tested, thereby further improving the reliability of the test of the optoelectronic hybrid connector to be tested.

[0034] The optoelectronic hybrid connector test system of this embodiment includes an optoelectronic hybrid connector to be tested, an insertion loss tester, an electrical conductor device and a power supply device, wherein the first end of the optoelectronic hybrid connector to be tested includes an electrical interface and a first optical fiber interface, the electrical interface includes a conductive metal copper sheet, the conductive metal copper sheet and the insertion loss tester are connected to the power supply device, the first optical fiber interface is connected to the first terminal of the standard optical fiber, the second terminal of the standard optical fiber is connected to the reference end of the insertion loss tester, the second end of the optoelectronic hybrid connector to be tested is connected to the first optoelectronic terminal of the optoelectronic hybrid cable, and the second optoelectronic terminal of the optoelectronic hybrid cable is connected to the measuring end of the insertion loss tester or the electrical conductor device. The system can realize the optoelectronic integrated test of the optoelectronic hybrid connector by flexibly switching the wiring mode of the second optoelectronic terminal of the optoelectronic hybrid cable, which significantly improves the test efficiency and operation convenience.

[0035] Example 2

[0036] The difference from Example 1 is that Figure 2 As shown, the electrical conductor device of this embodiment includes an optoelectronic hybrid connector and a display component, the second optoelectronic terminal of the optoelectronic hybrid cable is connected to the first optoelectronic terminal of the optoelectronic hybrid connector, and the second optoelectronic terminal of the optoelectronic hybrid connector is connected to the display component. Among them, the second optoelectronic terminal of the optoelectronic hybrid connector is connected to the display component through a power line. Specifically, the power supply device, the optoelectronic hybrid connector to be tested, the optoelectronic hybrid cable, the optoelectronic hybrid connector in the electrical conductor device and the display component constitute a complete electrical performance test circuit, and the display component is used to display whether the current test circuit is conductive. Preferably, the display component is a power signal light. After the power is turned on, if the power signal light is on, it means that the optoelectronic hybrid connector is conductive and the electrical performance is normal. If the power signal light is not on, it means that the optoelectronic hybrid connector is disconnected and the electrical performance is abnormal.

[0037] The electrical conductor device of this embodiment includes an optoelectronic hybrid connector and a display component, which can directly display whether the electrical performance of the optoelectronic hybrid connector to be tested is normal, thereby further improving the test efficiency.

[0038] Example 3

[0039] like Figure 3 As shown, this embodiment also provides a test method for the optoelectronic hybrid connector test system in the above embodiment, which specifically includes the following steps:

[0040] Step S1, connecting the second optoelectronic connector of the optoelectronic hybrid cable to a return loss tester.

[0041] Specifically, after the second optoelectronic connector of the optoelectronic hybrid cable is connected to the insertion-return loss tester, the optoelectronic hybrid connector to be tested, the standard optical fiber, the insertion-return loss tester and the optoelectronic hybrid cable form an optical performance test loop.

[0042] Step S2, judging whether the optical performance of the optical-electrical hybrid connector to be tested is normal according to the test result of the insertion-return loss tester.

[0043] For example, if the test results show that the insertion loss is less than 0.3dB and the return loss is greater than 30dB, the optical performance of the optical hybrid connector to be tested is considered to meet the standard. These two parameters are key indicators for evaluating the performance of optical connectors. Low insertion loss means high signal transmission efficiency, and high return loss means less reflected signal and high signal quality. Figure 2 Taking the insertion and return loss tester in as an example, the test results show that at a wavelength of 1550nm, the insertion loss is 0.18dB and the return loss is 52.8dB, indicating that the optical performance of the optoelectronic hybrid connector to be tested is in normal state.

[0044] Step S3, connecting the second optoelectronic terminal of the optoelectronic hybrid cable to the electrical conductor device.

[0045] Step S4: judging whether the electrical performance of the optoelectronic hybrid connector to be tested is normal according to the test result of the electrical conductor device.

[0046] Specifically, after the optical performance test is completed, the second optoelectronic connector of the optoelectronic hybrid cable is switched from the insertion loss tester to the electrical conductor device for the next electrical performance test. The test result of the electrical conductor device will directly reflect the electrical state of the optoelectronic hybrid connector to be tested, including whether it is currently in the on or off state.

[0047] In addition, in order to ensure the accuracy of the test results, the following steps are also included before step S1:

[0048] Step S0, calibrating the insertion-return loss tester.

[0049] The calibration process can eliminate the instrument's own errors and ensure the reliability of the test data.

[0050] The testing method of the optoelectronic hybrid connector testing system of the present embodiment realizes optoelectronic integrated testing of the optoelectronic hybrid connector by flexibly switching the wiring mode of the second optoelectronic wiring head of the optoelectronic hybrid cable, thereby significantly improving the testing efficiency and the convenience of operation.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
