Description

Technical Field

It is widely used in the communication field.

[0003] The performance of a complete fiber optic link depends not only on the quality of the fiber itself, but also on the quality of the connector, the construction process and the site environment. Therefore, on-site testing of fiber optic links is crucial, and real-time testing of fiber optic links is an essential part of installing and maintaining fiber optic networks. Its main purpose is to follow specific standards to detect the quality of fiber optic system connections, reduce failure factors, and find out the fault point of the fiber when a fault exists, so as to further find the cause of the fault.

[0004] When conducting on-site testing of optical fiber links, it is necessary to test the attenuation changes in different environments to verify the performance of the optical fiber at different ambient temperatures. However, the existing on-site testing method for optical fiber links is: when the optical fiber reaches the set temperature, the attenuation and other indicators of the optical fiber are manually measured. During the test, technicians are required to repeatedly manually test the optical fiber and record the relevant data, and then analyze and process the data and generate relevant reports. This manual measurement method has relatively low work efficiency when measuring a large number of optical fibers. Summary of the invention

[0039] In this embodiment, the present invention performs real-time detection of the performance of the optical fiber link through the detection module 101, and transmits the detection to the analysis and processing module 104 through the optical transmitting end 102 and the optical receiving end 103, so that the analysis and processing module 104 analyzes and processes the test results, and compares them with preset values ​​after analysis and processing to obtain a comparison result, so that the alarm module 105 can determine whether to issue a warning signal according to the comparison result. During the entire test process of the optical fiber link, no manual measurement is required, thereby improving work efficiency and solving the problem that most of the existing field tests of optical fiber links use manual measurement of optical fiber attenuation and other indicators for testing, and when measuring a large number of optical fibers, there is a technical problem of relatively low work efficiency.

[0040] Among them, the detection module 101, the optical transmitting end 102, the optical receiving end 103, the analysis and processing module 104 and the alarm module 105 are connected in sequence; the detection module 101 is used to perform real-time detection of the optical fiber link performance; the optical transmitting end 102 is used to convert the detection result into an optical fiber signal and send it out; the optical receiving end 103 is used to receive the transmitted optical fiber signal; the analysis and processing module 104 is used to analyze and process the received optical fiber signal, and compare the processing result obtained by the analysis with the preset value to obtain a comparison result; the alarm module 105 is used to determine whether to issue a warning signal based on the comparison result.

[0041] Secondly, the division unit 109 is connected to the test unit 111 through the matching unit 110; the division unit 109 is used to pre-divide the optical fiber link into multiple parts and send the division result to the matching unit 110; the matching unit 110 is used to match the corresponding test pulse for each part of the optical fiber link network and send the matching result to the test unit 111; the test unit 111 is used to test each part of the optical fiber link network according to the preset test wavelength using the corresponding test pulse and obtain the test result.

[0042] Again, the processing unit 112 and the comparison unit 113 are connected; the processing unit 112 is used to convert the received optical fiber signal into an electrical signal, analyze and process the electrical signal, and then send the processing result to the comparison unit 113; the comparison unit 113 is used to compare the processing result with the preset value to obtain a comparison result.

[0043] At the same time, the early warning unit 114 is connected to the emergency braking unit 115; the early warning unit 114 is used to determine whether to issue a warning signal based on the comparison result, and send a braking command to the emergency braking unit 115 when a serious fault occurs in the test system; the emergency braking unit 115 is used to emergency stop the operation of the real-time test system according to the braking command.

[0044] In addition, the storage module 106 is connected to the detection module 101 and is used to store the test results of the detection module 101 .

[0045] In addition, the display module 107 is connected to the detection module 101 and is used to display the test results detected by the detection module 101 .

[0046] Finally, the power supply module 108 is connected to the detection module 101 to provide power for the operation of the detection module 101, and the power supply 116 is connected to the power manager 117; the power supply 116 is used to supply power to the detection module 101. The power manager 117 is used to manage the charging and discharging of the power supply 116.

[0047] When using a real-time optical fiber link performance test system of this embodiment, the power supply module 108 is used to power the operation of the detection module 101, and then the division unit 109 is used to pre-divide the optical fiber link into multiple parts and send the division result to the matching unit 110. Thereafter, the matching unit 110 matches the corresponding test pulse for each part of the optical fiber link network and sends the matching result to the test unit 111, so that the test unit 111 can test each part of the optical fiber link network according to the preset test wavelength using the corresponding test pulse and obtain the test result, thereby realizing real-time detection of the performance of the optical fiber link. When the entire detection module 101 is running, the detection module 101 will transmit the test result to the storage module 106, so that the storage module 106 stores the test result. At the same time, the detection module 101 will transmit the test result to the display module 107, so that the display module 107 displays the test result detected by the detection module 101.

[0048] After detection, the optical transmitting end 102 is used to convert the test result into an optical fiber signal and send it out. Thereafter, the optical fiber signal is received by the optical receiving end 103 and transmitted to the processing unit 112, so that the processing unit 112 can convert the received optical fiber signal into an electrical signal and analyze and process the electrical signal. After analysis and processing, the processing result is sent to the comparison unit 113, so that the comparison unit 113 can compare the processing result with the preset value to obtain a comparison result. When the comparison result is greater than the preset value, it is determined that the optical fiber link has not failed and no alarm information is sent; when the comparison result is less than the preset value, it is determined that the optical fiber link has failed. At this time, the early warning unit 114 will send a warning signal to warn. When a serious fault occurs in the test system, the early warning unit 114 will send a braking command to the emergency braking unit 115, so that the emergency braking unit 115 can urgently stop the operation of the real-time test system according to the braking command.

[0049] In summary, the present invention performs real-time detection of the performance of the optical fiber link through the detection module 101, and transmits the detection to the analysis and processing module 104 through the optical transmitting end 102 and the optical receiving end 103, so that the analysis and processing module 104 analyzes and processes the test results, and compares them with preset values ​​after analysis and processing to obtain a comparison result, so that the alarm module 105 can determine whether to issue a warning signal according to the comparison result. During the entire test process of the optical fiber link, no manual measurement is required, thereby improving work efficiency and solving the problem that most of the existing field tests of optical fiber links are conducted by manually measuring indicators such as optical fiber attenuation. When measuring a large number of optical fibers, there is a technical problem of relatively low work efficiency.

[0055] S104, comparing the processing result obtained by analysis with the preset value to obtain a comparison result;

[0056] S105. When the comparison result is greater than the preset value, it is determined that the optical fiber link has not failed, and no warning information is sent;

[0057] S106 . When the comparison result is less than the preset value, it is determined that a failure occurs in the optical fiber link, and an alarm message is sent through the alarm module 105 .

[0058] When using a real-time test method for optical fiber link performance of the present embodiment, the power supply module 108 is used to power the operation of the detection module 101, and then the division unit 109 is used to pre-divide the optical fiber link into multiple parts and send the division result to the matching unit 110. Thereafter, the matching unit 110 matches the corresponding test pulse for each part of the optical fiber link network and sends the matching result to the test unit 111, so that the test unit 111 can test each part of the optical fiber link network according to the preset test wavelength using the corresponding test pulse and obtain the test result, thereby realizing real-time detection of the performance of the optical fiber link. When the entire detection module 101 is running, the detection module 101 will transmit the test result to the storage module 106, so that the storage module 106 stores the test result. At the same time, the detection module 101 will transmit the test result to the display module 107, so that the display module 107 displays the test result detected by the detection module 101.

[0059] After detection, the optical transmitting end 102 is used to convert the test result into an optical fiber signal and send it out. Thereafter, the optical fiber signal is received by the optical receiving end 103 and transmitted to the processing unit 112, so that the processing unit 112 can convert the received optical fiber signal into an electrical signal and analyze and process the electrical signal. After analysis and processing, the processing result is sent to the comparison unit 113, so that the comparison unit 113 can compare the processing result with the preset value to obtain a comparison result. When the comparison result is greater than the preset value, it is determined that the optical fiber link has not failed and no alarm information is sent; when the comparison result is less than the preset value, it is determined that the optical fiber link has failed. At this time, the early warning unit 114 will send a warning signal to warn. When a serious fault occurs in the test system, the early warning unit 114 will send a braking command to the emergency braking unit 115, so that the emergency braking unit 115 can urgently stop the operation of the real-time test system according to the braking command.
