Description

Technical Field

[0001] The present application relates to the technical field of optical fiber communication equipment, and in particular to a photoelectric hybrid connector testing system. Background Art

[0002] Through active exploration by basic telecommunications companies, FTTR-B (Fiber to the Room for Business) has become an ideal solution for building gigabit optical networks for small and micro enterprises, thanks to its high bandwidth, excellent coverage, intelligent operation and maintenance, convenient deployment, and environmentally friendly energy conservation. With the widespread adoption of F5G and WiFi 6 / 7 in campuses, homes, and other scenarios, demand for hotspot applications such as all-optical campuses and all-optical homes is growing. This is accompanied by a surge in demand for scenarios such as fiber-to-the-desktop, fiber-to-the-camera, and fiber-to-the-access point (AP), which require the introduction of low-power terminals (rated voltage ≤48V, power ≤100W).

[0003] In response to this demand, the patent application with the existing announcement number CN221200008U proposes an optoelectronic hybrid connector, which uses a two-conductive pin design and integrates the dual functions of optical fiber communication and power transmission. Through a single optical fiber, the connector can complete the transmission of signals such as data, voice, and video, and simultaneously use a pair of conductors to transmit electrical energy, realizing the integration of data transmission and power supply, making line connections more convenient and reliable, and becoming a key solution for optical fiber to the end-of-line scenarios. At present, the FTTR-B master and slave devices are connected to each other through optoelectronic hybrid connectors. To ensure the quality of optoelectronic hybrid active connectors, they need to be measured with professional equipment. Among them, the insertion loss tester is used to test its optical performance, such as insertion loss value and other indicators; while the power supply detection equipment is used to test its electrical performance. However, there is currently no optoelectronic integrated testing solution on the market. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0019] Example 1

[0020] like Figure 1 As 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 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. 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 represented by a dotted line.

[0021] The electrical conductor device can be not only electrical performance testing equipment such as ammeters, voltmeters, and oscilloscopes, 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, and other signals, 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.

[0022] Specifically, when performing an optical performance test on an optoelectronic hybrid connector, the second optoelectronic connector of the optoelectronic hybrid cable is connected to the measurement end of an insertion and return loss tester. The optoelectronic hybrid connector, standard optical fiber, insertion and return loss tester, and optoelectronic hybrid cable now form an optical performance test loop. During the actual test, a light source (such as a laser) within the insertion and return loss tester sends an optical signal of known intensity and wavelength to the reference end. This optical signal is transmitted via the standard optical fiber to the first optical fiber interface of the optoelectronic hybrid connector, then travels through the optical path of the optoelectronic hybrid connector and enters the optoelectronic hybrid cable. After transmitting through the optoelectronic hybrid cable, the optical signal is received by the second optoelectronic connector and returned to the measurement end of the insertion and return loss tester. The insertion and return loss tester compares the optical signal received at the measurement end with the original transmitted signal to calculate insertion loss (i.e., the energy lost during signal transmission) and return loss (i.e., the degree of signal reflection from the connector back to the source end). These parameters reflect the optical performance of the optoelectronic hybrid connector. After the test is completed, the insertion and return loss tester displays the insertion and return loss values, along with a possible spectrum or waveform, to help testers intuitively understand the performance of the optoelectronic 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.

[0023] 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 polishing method for optical fiber connectors, and its characteristic is that the end face is specially polished to form a slight curvature to achieve more precise docking. This polishing method optimizes the end face polishing and surface finish, so that the optical fiber end face can be better contacted, reducing the air gap and thus reducing the insertion loss. The APC plug is another type of end face polishing method for optical fiber connectors, and its characteristic is that the optical fiber end face is polished into an 8° bevel. This bevel design not only makes the optical fiber end face contact more closely, 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 ends 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.

[0024] Furthermore, to improve the reliability of the optoelectronic hybrid connector test system, the optoelectronic hybrid connector test system also includes a calibration device connected to an insertion and return loss tester. Before conducting optical performance testing on the optoelectronic hybrid connector under test, the calibration device can be used to calibrate the insertion and return loss tester. 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.

[0025] Specifically, the light source module calibration component can include an optical power meter, which measures the power of the optical signal output by the light source module in the insertion-return loss tester. By comparing the measured value with a preset standard value, the light source module's power output can be calibrated to ensure stability and accuracy.

[0026] A power module calibration assembly may include a light source and an optical attenuator. The light source provides an optical signal of known power and wavelength for calibrating the power measurement module in an insertion and return loss tester. This light source can be tunable to enable calibration at different wavelengths. The optical attenuator adjusts the power level of the optical signal to simulate various power conditions encountered in actual use. By measuring the optical power at different attenuation levels, the sensitivity and accuracy of the power measurement module in the insertion and return loss tester can be calibrated.

[0027] The return-loss module calibration assembly may include a return-loss calibration fiber. This return-loss calibration fiber has known and stable return loss characteristics and is used to calibrate the return-loss measurement module in the insertion-return-loss tester. By connecting the return-loss calibration fiber to the tester's measurement port and measuring the power of the reflected signal, the power can be compared with the known return loss value to calibrate the return-loss measurement module in the insertion-return-loss tester. During the calibration process, the known return loss characteristics of the return-loss calibration fiber are used as a reference. By comparing these with the tester's measurement results, the calibration parameters of the insertion-return-loss tester can be adjusted, enabling it to accurately measure the reflection loss of optical signals.

[0028] When conducting an electrical performance test on an optoelectronic hybrid connector, the second optoelectronic connector of the optoelectronic hybrid cable is switched to the electrical conductor assembly. At this point, the power supply, the optoelectronic hybrid connector, and the electrical conductor assembly form a complete electrical performance test circuit. Specifically, a conductive copper sheet is positioned within the optoelectronic hybrid connector. One end of the sheet serves as an electrical interface for connection to the power supply, while the other end connects to the optoelectronic hybrid cable, forming an electrical path. After the power supply is activated, current flows through the electrical interface of the optoelectronic hybrid connector and the optoelectronic hybrid cable to the electrical conductor assembly. The electrical conductor assembly measures and displays the received current, providing intuitive and accurate test results to the tester.

[0029] Furthermore, if Figure 2As shown, the power supply device is an optical socket. The optical socket has its own internal power supply. In this case, both the electrical interface of the optoelectronic hybrid connector under test and the insertion / return loss tester can be connected to the optical socket via an optoelectronic hybrid cable. Specifically, when two conductive metal copper sheets are provided within the optoelectronic hybrid connector under test, the first ends of the two conductive metal copper sheets serve as separate electrical interfaces for connection to the optical socket, while the second ends are respectively connected to the first optoelectronic connectors of the optoelectronic hybrid cable, thereby forming two electrical performance test circuits. In this case, the optoelectronic hybrid cable connected to the optical socket provides two electrical signals to the two conductive metal copper sheets within the optoelectronic hybrid connector under test, thereby further improving the reliability of testing the optoelectronic hybrid connector under test.

[0030] The optoelectronic hybrid connector testing 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. The first end of the optoelectronic hybrid connector to be tested includes an electrical interface and a first optical fiber interface. The electrical interface is connected to the power supply device, the first optical fiber interface is connected to a first connector of a standard optical fiber, and the second connector of the standard optical fiber is connected to a reference terminal of the insertion loss tester. The second end of the optoelectronic hybrid connector to be tested is connected to a first optoelectronic connector of an optoelectronic hybrid cable, and the second optoelectronic connector of the optoelectronic hybrid cable is connected to a measuring terminal of the insertion loss tester or the electrical conductor device. This system can perform optoelectronic integrated testing of optoelectronic hybrid connectors by flexibly switching the wiring method of the second optoelectronic connector of the optoelectronic hybrid cable, significantly improving testing efficiency and operational convenience.

[0031] Example 2

[0032] 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. The second optoelectronic terminal of the optoelectronic hybrid connector is connected to the display component via a power cord. 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. 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 indicates that the optoelectronic hybrid connector is conductive and the electrical performance is normal. If the power signal light is off, it indicates that the optoelectronic hybrid connector is disconnected and the electrical performance is abnormal.

[0033] 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, further improving the test efficiency.

[0034] The test method of the optoelectronic hybrid connector test system of the present application specifically includes the following steps:

[0035] Step S0: calibrate the insertion-return loss tester.

[0036] Among them, the calibration process can eliminate the instrument's own errors and ensure the reliability of the test data.

[0037] Step S1: Connect the second optoelectronic connector of the optoelectronic hybrid cable to a return loss tester.

[0038] 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.

[0039] 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.

[0040] 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 tested optoelectronic hybrid connector is considered to meet the standards. 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 the test 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 condition.

[0041] Step S3: Connect the second optoelectronic connector of the optoelectronic hybrid cable to the electrical conductor device.

[0042] 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.

[0043] Specifically, after the optical performance test is completed, the second optoelectronic connector of the optical / electrical hybrid cable is switched from the insertion / return loss tester to the electrical conductor device for the next electrical performance test. The test results of the electrical conductor device directly reflect the electrical status of the optical / electrical hybrid connector under test, including whether it is currently in the on or off state.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0045] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
