Description

Technical Field

[0001] The present invention relates to the field of optical network communication technology, and in particular to an optical fiber line detection device, method, electronic equipment and storage medium. Background Art

[0002] With the rapid development of optical network communications, the complexity of optical network systems is increasing, the reliability and stability of optical fiber quality are becoming more and more obvious, and labor costs are increasing. The demand for optical time domain reflectometers for optical fiber line performance detection and fault location is increasing.

[0003] Usually, when using an optical time domain reflectometer to detect the optical fiber line to be detected, a fixed-cycle round-robin method is used for detection. By configuring an optical switch, multiple optical fiber lines can be detected. The detection resources required to complete a detection of multiple optical fiber lines increase exponentially according to the number of lines that need to be detected. In addition, the optical fiber line to be detected is in a normal state most of the time. Therefore, the use of a fixed-cycle round-robin method for detection not only wastes detection resources, but also greatly reduces the service life of the optical switch because the optical switch has a limit on the number of times it can be used.

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figure 1 The optical fiber line detection device of the present invention is described.

[0033] Please refer to Figure 1 , Figure 1 FIG. 1 is one of the structural diagrams of the optical fiber line detection device provided by the embodiment of the present invention. Figure 1 As shown, the device may include: a first site 1 and a second site 2. The first site 1 includes: a first transmission device 11, a power detection module 12, a line measurement module 13 and a first optical coupling module 14. The second site 2 includes: a second transmission device 21, a light source module 22 and a second optical coupling module 23. The first optical coupling module 14 and the second optical coupling module 23 are respectively connected to the two ends of the optical fiber 3 to be detected.

[0034] The first transmission device 11 and the second transmission device 21 both have a transmitting end and a receiving end. The transmitting end TX of the second transmission device 21 is used to input a service signal with a wavelength of λ1 to the first end of the second optical coupling module 23, and transmit it to the first optical coupling module 14 through the optical fiber 3 to be detected. The receiving end RX of the first transmission device 11 is used to receive the service signal output from the first end of the first optical coupling module 14. The transmitting end TX of the first transmission device 11 is used to send the service signal, which is transmitted to the receiving end RX of the second transmission device 21 through another optical fiber. In this way, the transmission of the service signal between the first transmission device 11 and the second transmission device 21 can be realized.

[0035] The light source module 22 is used to provide a continuous light source signal with a target wavelength of λ2, input the light source signal with a target wavelength of λ2 to the second end of the second optical coupling module 23, and transmit it to the first optical coupling module 14 through the optical fiber 3 to be detected. The input end of the power detection module 12 is used to receive the light source signal with a target wavelength of λ2 output from the second end of the first optical coupling module 14. In this way, the light source signal with a target wavelength of λ2 can be transmitted to the power detection module 12 through the optical fiber 3 to be detected. The target wavelength λ2 is different from the wavelength λ1 of the business signal and the wavelength λ3 of the test signal, so that the light source signal with a target wavelength of λ2 can be prevented from affecting the business signal and the test signal.

[0036] Optionally, the luminous light source module 22 includes a hot-swappable optical transceiver for providing a stable light source signal.

[0037] The power detection module 12 is used to detect the optical power value of the received light source signal of the target wavelength in real time, and determine that the optical fiber line of the optical fiber 3 to be detected is degraded or broken when the optical power value meets the test condition of being continuously lower than the preset threshold value within a preset period, thereby avoiding detection errors caused by signal disturbances when only detecting the optical power value at a certain moment.

[0038] It should be noted that the preset threshold is determined according to the optical power value of the optical fiber 3 under normal conditions. For example, the optical power value detected by the power detection module 12 of the optical fiber 3 under normal conditions is P1, the safety range is set to 5db, and the preset threshold is set to P1-5.

[0039] The line measurement module 13 is used to send a test signal to the third end of the first optical coupling module 14 when the optical fiber line of the optical fiber 3 to be detected is degraded or broken, and the third end of the second optical coupling module 23 is suspended to locate the optical fiber degradation or optical fiber breakpoint of the optical fiber 3 to be detected. In this way, the line measurement module 13 will be triggered to perform optical fiber line detection only when the optical power value meets the test conditions, and the optical fiber line detection will not be performed in a fixed periodic rotation mode, which can improve the utilization rate of detection resources and the service life of the line measurement module 13. In addition, the power detection module 12 can detect the optical power value of the received target wavelength light source signal in real time, so that it can detect in real time whether the optical fiber is degraded or broken, and quickly locate the optical fiber degradation or optical fiber breakpoint when the optical fiber is degraded or broken.

[0040] Therefore, the optical fiber line detection device provided in this embodiment can improve the utilization rate of detection resources and the service life of the line measurement module, and can also detect in real time whether the optical fiber is degraded or broken, and quickly locate the optical fiber degradation or the optical fiber break point when the optical fiber is degraded or broken.

[0041] In one embodiment, if Figure 1As shown, the line measurement module 13 includes an optical time domain reflectometer (OTDR) 131 and an optical switch 132 , and the OTDR 131 is connected to the optical switch 132 .

[0042] The optical switch 132 is used to select the optical fiber to be tested when the optical fiber line of the optical fiber 3 to be tested is degraded or broken. The optical time domain reflectometer 131 is used to send a test signal to the third end of the first optical coupling module 14, and locate the optical fiber degradation or optical fiber break point of the optical fiber 3 to be tested according to the test result.

[0043] Specifically, the working principle of the optical time domain reflectometer 131 is: in an optical communication network, the backscattering caused by Rayleigh scattering and Fresnel reflection when light is transmitted in the optical fiber is used to realize the optical time domain reflection function, thereby realizing the measurement of optical fiber length, transmission attenuation, joint attenuation, fault location, etc.

[0044] Only when the optical power value meets the test condition of being continuously lower than the preset threshold value within a preset period, and the optical fiber line of the optical fiber 3 to be detected is determined to be degraded or broken, will the optical switch 132 be triggered to select the optical fiber to be detected, and the optical time domain reflectometer 131 will start to perform optical fiber line detection to locate the optical fiber degradation or optical fiber breakpoint position of the optical fiber 3 to be detected. The optical fiber line detection will not be performed in a fixed period rotation mode all the time, which can improve the utilization rate of detection resources and the service life of the optical switch 132.

[0045] Therefore, this embodiment can improve the utilization rate of detection resources and the service life of the optical switch.

[0046] In one embodiment, if Figure 2 As shown, the device further includes: a main control module 4, which is connected to the power detection module 12 and the line measurement module 13 respectively.

[0047] Optionally, there are multiple optical fibers to be detected, and there are multiple ports of the optical switch 132, and each optical fiber to be detected has a corresponding port of the optical switch 132. In this way, multiple optical fibers can be supported for optical fiber line detection.

[0048] The power detection module 12 is used to generate an alarm instruction when the optical power value meets the test condition of being continuously lower than a preset threshold value within a preset period, and send the alarm instruction to the main control module 4.

[0049] The main control module 4 is used to control the optical switch 132 to switch to the corresponding port based on the alarm instruction, and control the optical time domain reflectometer 131 to send a test signal to the third end of the first optical coupling module for testing. The optical switch 132 can be switched to the port corresponding to the identifier of the optical fiber to be detected that generates the alarm according to the identifier of the optical fiber to be detected carried in the alarm instruction, thereby controlling the optical time domain reflectometer 131 to send a test signal to the third end of the first optical coupling module for testing. Optionally, the main control module 4 includes a microcontroller.

[0050] In this embodiment, the optical power value can be detected in real time by the power detection module. When the optical power value meets the test condition of being continuously lower than the preset threshold value within a preset period, an alarm instruction is generated and sent to the main control module. The main control module controls the optical switch to switch to the corresponding port, and controls the optical time domain reflectometer to send a test signal to the third end of the first optical coupling module for testing. The optical switch can be controlled to switch to the corresponding port in time so that the optical time domain reflectometer can quickly locate the fiber degradation condition or the fiber breakpoint position of the faulty optical fiber.

[0051] Optionally, the first optical coupling module 14 includes a first wavelength division multiplexer (WDM), and the second optical coupling module 23 includes a second wavelength division multiplexer. In this way, when at least two of the service signal, the test signal, and the light source signal need to be transmitted at the same time, the wavelength division multiplexer can couple at least two of the service signal, the test signal, and the light source signal to one optical fiber for transmission.
