Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical fiber fusion splicing, and in particular to an attenuation fusion splicing method and system based on optical fiber fusion splicing. Background Art
[0002] In modern fiber-optic communication systems, maintaining optical signal strength within an appropriate range is crucial for ensuring stable equipment operation and improving user experience. In practical applications, there are numerous scenarios where precise control of optical signal strength is required. For example, various optical fiber-connected devices typically have clear input optical power thresholds. Excessively strong optical signals can cause equipment malfunction or performance impairment. In fiber-to-the-home (FTTH) network deployments, the varying transmission distances between users and the central office result in uneven optical signal strength at each terminal, impacting service quality. Therefore, optical signal conditioning is necessary to ensure that each user receives a stable and appropriate signal level.
[0003] At present, the commonly used method of attenuating optical signals is to connect special optical attenuation devices at designated locations, through which the optical signal is quantitatively attenuated to achieve the expected intensity. Although this method can meet engineering needs to a certain extent, it also has obvious defects: on the one hand, different application scenarios often require devices with different attenuation values, resulting in a wide variety of equipment and complex maintenance; on the other hand, the additional introduction of attenuation elements will also increase the number of connection nodes in the system, thereby increasing the probability of failure and reducing overall reliability. Another implementation method is to use a fiber fusion splicer to perform "attenuation fusion", that is, by adjusting the fusion parameters to produce controllable loss at the fiber connection, thereby achieving the purpose of attenuating the optical signal. However, it is difficult to achieve high-precision attenuation control by relying solely on existing fusion equipment. The actual attenuation value after fusion often deviates from the target value, with large errors, making it difficult to meet application scenarios with high precision requirements.
[0004] Therefore, how to provide an attenuation fusion splicing method and system based on optical fiber fusion splicing is a problem that needs to be solved urgently. Summary of the Invention

[0072] In this optional embodiment, the target attenuation value is in the range of 0-15 decibels.
[0073] In this optional embodiment, the attenuation function includes: a lateral misalignment function and a dynamic adjustment function.
[0074] In this optional embodiment, controlling the optical fiber fusion splicer to discharge the target optical fiber according to the set target attenuation value, calculating the movement amount of the core-aligning motor using the attenuation function, and moving the core-aligning motor based on the movement amount to introduce attenuation includes:

[0076] During the spark welding process, the movement of the centering motor is calculated using the decay function;
[0077] According to the calculated movement amount, the core-aligning motor is controlled to move and pull the target optical fiber to introduce the required attenuation value during the fusion process.

[0079] In this optional embodiment, during the discharge welding process, calculating the movement amount of the alignment motor using the attenuation function includes:
[0080] During the discharge welding process, use an optical power meter to read the optical power value after each discharge welding;
[0081] Calculate the difference between the current optical power value and the optical power value after the last discharge welding to determine the actual attenuation value of the current discharge attenuation;

[0083] In this optional embodiment, the determining whether the current total attenuation value reaches the target attenuation value, if not, updating the pending attenuation value, and repeating the alignment motor calculation, discharge welding, and attenuation calculation processes until the total attenuation value reaches the target attenuation value includes:
[0084] According to the calculated current attenuation total value, determine whether the current attenuation total value reaches the set target attenuation value;
[0085] If the set target attenuation value is reached, the process is terminated and the attenuation welding is completed;
[0086] If the set target attenuation value is not reached, the updated attenuation value is calculated based on the current total attenuation value and the target attenuation value. Based on the updated attenuation value, the movement amount of the centering motor is recalculated, and the discharge welding and attenuation value calculation process is continued until the total attenuation value reaches the set target attenuation.
[0087] It should be noted that, in a specific embodiment, Figure 4 As shown, the attenuation fusion splicing method based on optical fiber fusion splicing includes: an optical fiber fusion splicer, an attenuation feedback module and a CPU control module.
[0088] The fiber fusion splicer is responsible for the attenuation splicing of optical fibers. First, the splicing function of the fiber fusion splicer is used to complete the normal splicing of the target optical fiber. After the splicing is completed, the attenuation loss of the target optical fiber is very small and can be ignored. Then the CPU controls the fiber fusion splicer to perform attenuation splicing: the splicing point of the target optical fiber is used as the attenuation point, and the electrodes of the splicer are controlled to generate discharge to melt this splicing point. While melting, the core-adjusting motor is moved to pull the optical fiber, causing a lateral misalignment of yμm in the optical fiber, resulting in a certain loss, thereby realizing the attenuation splicing function. The target attenuation value range that can be set for the attenuation splicing function is 0-15dB (decibels). The lateral misalignment yμm generated by the moving core-adjusting motor is determined by the basic function y=f1(x) and the function y=f2(x) that is dynamically fine-tuned after adding the real-time attenuation feedback model. x is the specific target attenuation value set (dB). Figure 5 (A is optical fiber, B is core) and Figure 6 Figure 2 shows a schematic diagram of optical fiber lateral misalignment at different angles.
[0089] The attenuation feedback module is controlled by the CPU and an optical power meter, which implements the real-time feedback system. The optical power meter reads the optical power value after splicing in real time and provides timely feedback to the CPU. The CPU then calculates the actual attenuation value after discharge decay based on the feedback. During the subsequent discharge decay process, the alignment motor movement distance is dynamically adjusted to ensure the attenuation value of the decay splice is accurate to a high accuracy of ±0.03dB. The actual attenuation value calculation method is as follows: The CPU records the optical power value after each discharge decay. The difference between the optical power value after the current discharge decay and the optical power value after the previous discharge decay is the actual attenuation value after the current discharge decay. The alignment motor movement distance is dynamically adjusted: Based on the error between the actual attenuation value after the previous discharge decay and the target attenuation value, the alignment motor movement distance for the current discharge decay, as calculated by the function y = f1(x), is adjusted in conjunction with the attenuation regression model to reduce the error of the current discharge decay.
[0090] The CPU control module is responsible for coordinating the work between the fiber fusion splicer and the attenuation feedback module. According to the target attenuation value xdB, it controls the specific movement distance yμm of the core-aligning motor during the attenuation fusion process of the fiber fusion splicer. After the attenuation is completed, it obtains the real-time feedback of the attenuation value and dynamically adjusts the movement amount of the core-aligning motor during the next attenuation step of the fusion splicer, reducing the error caused by external environmental factors and controlling the attenuation accuracy of the fusion point within the range of ±0.03dB.
[0091] There is a certain functional relationship between the target attenuation value xdB and the moving distance yμm of the core-aligning motor during the attenuation welding process. During the first attenuation welding process after the target optical fiber completes normal welding, the attenuation error caused by external factors is still in an unknown state. Therefore, the moving distance of the core-aligning motor in the first attenuation welding is determined according to the basic function y=f1(x).
[0092] Due to the aging problem of the electrode rod of the optical fiber fusion splicer caused by the increase in the number of discharges and other external environmental factors, there will be a certain error in the actual attenuation value after discharge. During the second and subsequent discharge attenuation processes, the real-time feedback system needs to feedback the actual attenuation value after the last discharge attenuation to control the attenuation accuracy. The moving distance yμm of the core-adjusting motor after adding the feedback value is in a functional relationship y=f2(x) with the target attenuation value xdB. The attenuation regression model is introduced into this function to dynamically adjust the result y. In this process, after the real-time feedback system obtains the attenuation value, the CPU will determine whether the attenuation value reaches the set target attenuation value. If it reaches it, the attenuation is completed. If it does not reach it, it is necessary to calculate the attenuation value in combination with the target attenuation value. After calling the function y=f2(x) again to determine the moving distance of the core-adjusting motor, discharge attenuation is performed, and the above content is repeated until the set target attenuation is reached. Figure 7 The figure shows the schematic diagram after attenuation welding is completed.
[0093] Determination of the functions y = f1(x) and y = f2(x):
[0094] 1. Based on the relationship between theoretical dislocation distance and attenuation, combined with the specific data obtained from multiple attenuation welding using different welding machines in the laboratory, data fitting is performed to obtain the basic curve function:
[0095]
[0096] Where y1 represents the lateral displacement of the core-aligning motor; r represents the fiber core radius; x represents the target attenuation value; and w represents the attenuation constant. This is the function y=f1(x).
[0097] 2. Due to the aging of the electrode rods in the fiber fusion splicer as the number of discharges increases, and the influence of external environmental factors, there will be a certain error in the actual attenuation value. It is necessary to obtain the real-time attenuation value calculated by the attenuation feedback module, and then add an attenuation regression model based on the y=f1(x) function to dynamically adjust the movement of the core alignment motor to ensure attenuation accuracy. The function after adding the attenuation regression model is:
[0098]
[0099] Where y2 represents the adjustment movement of the core-aligning motor; r represents the fiber core radius; x represents the target attenuation value; w represents the attenuation constant; L trepresents the target attenuation value after discharge attenuation; L1 represents the actual attenuation value after discharge attenuation; d represents the distance moved by the discharge alignment motor, which is the function y=f2(x).
[0100] The specific implementation process is as follows:
[0101] 1. Enter the specific target attenuation value.
[0102] 2. Place the optical fiber into the optical fiber fusion splicer and fusion-splice the optical fiber normally. The loss after fusion is completed is 0dB.
[0103] 3. The optical power meter in the attenuation feedback module reads the optical power after splicing. The CPU uses the optical power value at this time as the initial reference optical power value, and the attenuation at this time is 0dB. The attenuation value x (dB) is the set target attenuation value.
[0104] 4. Based on the functional relationship between the attenuation value x (dB) and the movement amount y (μm) of the welding machine's centering motor, the CPU can calculate the specific movement amount y (μm) of the next centering motor. The CPU will call y = f1 (x) or y = f2 (x) according to the process.
[0105] 5. The electrodes of the optical fiber fusion splicer discharge to melt the optical fiber, and at the same time the core-adjusting motor moves the specified amount y (μm). This process causes loss at the optical fiber fusion point, which is called attenuated fusion.
[0106] 6. Attenuation feedback module calculates actual attenuation value: After the discharge is completed, the optical power meter in the attenuation feedback module reads the optical power value again. The CPU calculates the attenuation value of this attenuation welding and combines it with the benchmark optical power value to calculate the total attenuation value m (dB).
[0107] 7. Determine whether the attenuated value m(dB) has reached the target attenuation value. If so, the attenuation welding is complete. If not, calculate the expected attenuation value x(dB) based on the total attenuated value m(dB) and the set target attenuation value. Repeat steps 4-6 until the target attenuation value is reached.
[0108] Through the above steps, the accuracy of attenuation welding can be controlled within ±0.03dB. Figure 8 shown.
[0109] In addition, the fiber fusion splicing function of the fiber fusion splicer and the feedback attenuation value in the real-time feedback system cooperate with each other. After the CPU controls the fusion splicer to move the core-aligning motor to complete the attenuation of the optical fiber each time it discharges, it is necessary to read the optical power value in time through the optical power meter in the attenuation feedback module, calculate the actual attenuation value to complete the attenuation feedback. According to the actual attenuation value fed back and combined with the attenuation regression model, the CPU dynamically adjusts the movement amount of the core-aligning motor during the next discharge attenuation of the fusion splicer, eliminates the influence of external environmental factors, thereby greatly reducing the error of attenuation fusion and controlling the attenuation accuracy of the fusion point within the range of ±0.03dB.
[0110] Compared to using an attenuation device, the splice point has no additional components, making it less susceptible to damage, reducing potential failure points, and offering high reliability. A wide range of selectable attenuation values allows for setting any value within the attenuation range, providing greater flexibility. In practical scenarios, the target attenuation value can be achieved through simple operations without complex debugging. Compared to using only a fiber fusion splicer for attenuation splicing, the integrated attenuation feedback module enables dynamic adjustment during the attenuation process, eliminating the influence of external environmental factors and significantly improving attenuation accuracy.
