[0002] Optical boards play a crucial role in optical communication systems. They mainly utilize the high-speed transmission characteristics of light to transmit and communicate digital signals. Specifically, the working process of an optical board includes the following steps:

[0003] Optoelectronic conversion: The light-emitting device of the optical board converts digital signals into optical signals.

[0004] Optical signal transmission: Using optical fibers as the transmission medium, the optical signals are transmitted from one end to the other end.

[0005] Optoelectronic conversion: At the receiving end, the receiving device converts the optical signals back into digital signals, thus completing the signal transmission and communication.

[0006] Optical boards are the main components of transmission equipment and are relatively expensive, with a single board price of about 100,000 yuan. When dealing with the test of transmission optical cable line faults, it is necessary to leave someone in the computer room to cooperate, and disconnect the fiber jumpers between the equipment and the line to conduct the test. Due to improper testing, damage to the optical boards of transmission equipment often occurs. Since the transmission computer room is relatively far away, most distances are more than dozens of kilometers. Each time a test is conducted, someone needs to be left in the computer room to cooperate for work such as disconnecting, restoring, discharging light, and identifying the optical core line sequence of the line. The current methods for testing transmission optical cable line faults have problems such as consuming a large amount of human resources and low work efficiency. Summary of the Utility Model

[0094] During the optical cable emergency repair process, when the optical cable break point is found, in order to determine whether the front end of the optical cable is damaged, it is necessary to measure the optical power at the break point to judge whether there is still damage at the front end of the optical cable. The specific implementation is as follows: Adjust the mode key 19, decrease key 21, and increase key 20 on the front panel buttons of the A device 27 to the light source state, and the working status indicator light 18 is lit. At this time, the A device 27 emits a standard light source with a wavelength of 1550 nm and a power of -4 dBm internally. Then press the mode key 19 again to make it work in the twelve-channel IO optical interface 3 area. By pressing the decrease key 21 or the increase key 20, select the optical core to be tested. At this time, the optical power of the optical core can be tested at the optical cable fault point 33 through the optical power meter. Taking the light source index as a reference, it can be known which optical core is damaged by comparison. For the measurement and calculation of the optical cable loss, switch the -4 dB 1550 nm optical signal generator 11 built in the A device 27 to the optical core to be measured, and connect the optical power meter to the test end to measure the received power. The measured loss value is calculated by the formula: actual loss value = light source power - measured loss value. For example, when the measured value is -10 dBm and substituted into the formula, the actual loss value = -4 dBm - 10 dBm, and the loss value is 6 dBm. This function can also be operated remotely.

[0095] 4. Optical Cable Optical Core Identification Embodiment:

[0096] During the optical cable emergency repair process, especially when multiple optical cables are intertwined, the scene is relatively messy. The optical core arrangement and naming methods of optical cables from different manufacturers are different. During the fusion splicing process, it is easy to misalign the optical cores, which is commonly known as "interleaving". The fiber optic identification can be achieved through the 650nm red light source signal generator 12 built in the A device 27. Adjust the mode key 19, decrease key 21, and increase key 20 on the front panel of the A device 27 to the red light source state. The working status indicator light 18 is lit. At this time, a standard red light source with a wavelength of 650nm is emitted inside the A device 27. Then press the mode key 19 again to make it work in the twelve-channel IO optical interface 3 area. By pressing the decrease key 21 or increase key 20, select the optical core to be identified and send red visible light. At the optical cable fault location 33, the arrangement order rule of the optical cores can be judged by observing the red light with the naked eye, and the maximum detection distance can reach 30 kilometers. This function can also be operated remotely.

[0097] 5. Embodiment of the temporary call of the pigtail in the optical path:

[0098] When repairing the damaged backbone optical cable, especially when the optical cable is hung up by a vehicle or damaged by a large external force, after the optical cable fusion splicing is completed, there will be index differences, and at this time, there will be a situation where the OTN transmission device 24 cannot be turned on. In order to save the time for restoration, the optical core with better indicators in the optical cable 32 can be temporarily and preferentially called by using the A device 27 according to the principle of prioritizing communication. This method of calling is flexible, does not require manual replacement, saves time, and reduces the interruption time. This function can also be operated remotely.

[0099] The result of the present utility model is compact in volume, with a standard 1U chassis appearance, and can be installed on the rack or used as a desktop computer. This device is installed in the computer room and connected to the PTN transmission equipment end, and the following effects can be achieved in actual use.

[0100] 1. When the optical cable is interrupted or fails and the line needs to be tested, the connection between the transmission equipment and the line can be automatically cut off through the 4G handheld terminal control device, which can effectively prevent the OTDR from emitting too strong light and damaging the optical board, and reduce the operation and maintenance cost.

[0101] 2. When conducting traditional long-distance trunk line tests, someone must stay in the computer room to cooperate. After making the connection of the pigtail in advance for the present utility model, there is no need for someone to stay in the computer room to cooperate, which improves the measurement efficiency and saves human resources.

[0102] 3. The control distance of this device is not limited, and it can be operated locally or remotely. The working conditions of the device can be displayed on the panel LCD liquid crystal display screen, which is convenient for troubleshooting during remote operation at the field fault point.

[0103] 4. The device is designed with an embedded optical signal generator, which can provide a stable signal source of 1550nm at -4dBm. When measuring the loss of the optical cable, it is used as the reference level, and the online loss of the optical core line can be measured through the polling control function.

[0104] 5. The device is also designed with an embedded red visible light signal generator, and the line sequence identification of the online optical core can be realized through the polling control function.

[0105] 6. The test interface of the device can be used for reverse testing of the line with an OTDR optical time domain reflectometer, and the optical power value of the line can also be measured through an optical power meter. Through the polling switching function, it is possible to avoid plugging and unplugging the optical fiber back and forth, improving the efficiency of reverse testing. The measurement results can be sent to the handheld mobile terminal of the on-site emergency repair personnel through the image transmission function, making the line indicators after emergency repair clear at a glance.

[0106] 7. In case of emergency, the optical core with better online indicators can be temporarily scheduled, with a fast switching speed, which can reduce the service interruption time.

[0107] 8. During daily service activation or line call, it can be used as a multi-channel signal generator, saving service activation time.

[0108] 9. The insertion loss of the device is relatively low. After testing, the insertion loss of the device is below 1.8dBm, ensuring normal transmission indicators.

[0109] The utility model can prevent the OTDR optical time domain reflectometer from emitting too strong light when testing the optical cable line, avoiding the occurrence of damage to the optical board of the optical transmission device. It solves the problems of the need for someone to stay in the machine room for cooperation during line testing and the cumbersome operation of manually cutting off the connection between the line and the device. At the same time, it can also solve problems such as optical fiber identification and line length loss measurement in the optical cable line according to the test requirements.

[0110] The above content is only to illustrate the technical idea of the utility model, and the protection scope of the utility model cannot be limited by this. Any modification made on the basis of the technical solution according to the technical idea proposed by the utility model falls within the protection scope of the claims of the utility model.
