[0045] Specifically, when the alignment judgment submodule makes a judgment, the following principles are referred to: when the fiber end face alignment factor is greater than or equal to the selection threshold of the fiber end face alignment factor, it indicates that the fiber end face alignment effect is poor; when the fiber end face alignment factor is less than the selection threshold of the fiber end face alignment factor, it indicates that the fiber end face alignment effect is good; the selection threshold of the fiber end face alignment factor is set by technical personnel in this field.

[0046] Optionally, the visual detection submodule includes an image acquisition unit, an image processing unit and a data transmission unit; the image acquisition unit is used to acquire images; the image processing unit analyzes the acquired images through edge detection, shape fitting and center positioning and identifies the center point, highest point and lowest point of the optical fiber end face, and obtains the x-coordinate of the center point of each optical fiber end face, the x-coordinate of the highest point of each optical fiber end face and the x-coordinate of the lowest point of each optical fiber end face according to the center point, highest point and lowest point of the optical fiber end face, and transmits them to the data transmission unit; the data transmission unit transmits the x-coordinate of the center point of each optical fiber end face, the x-coordinate of the highest point of each optical fiber end face and the x-coordinate of the lowest point of each optical fiber end face to the control submodule.

[0055] Specifically, the units of the preset distance along the x-axis direction and the error distance along the x-axis direction are both millimeters, and the preset distance along the x-axis direction and the error distance along the x-axis direction are both set by those skilled in the art. The "preset distance along the x-axis direction" can be understood as the preset distance that one end of the optical fiber extends out of the end face of the corresponding component after the optical fiber is installed, and the corresponding "error distance along the x-axis direction" refers to the tolerance during processing of the optical fiber end face along the x-axis direction; the "x-coordinate" refers to the coordinate along the length direction of the optical fiber; in the "x-coordinate of the highest point of each optical fiber end face" and "x-coordinate of the lowest point of each optical fiber end face", the "highest point" and "lowest point" refer to the distance of the optical fiber end face from the coordinate axis (the origin of the coordinate axis will be set on the body of the optical fiber and away from the position of the tested end face of the optical fiber, for details, please refer to Figure 1 The preset value of the fiber flatness is set by those skilled in the art. The smaller the value of "flatness", the flatter it is. The larger the corresponding "flatness", the rougher the fiber surface is, which will cause greater errors and influences on the alignment measurement. The measured value of the fiber flatness can be obtained by the RMS (Root Mean Square) value obtained from the distance from each point on the fiber surface to the reference plane and the average of all distances.

[0056] The above units are only examples, and those skilled in the art may set different units according to actual needs when implementing this solution.

[0057] This embodiment solves the problem that the traditional manufacturing method is relatively single. By automatically detecting and feeding back the alignment effect, alignment problems can be discovered and corrected at an early stage, reducing the risk of rework after subsequent assembly is completed.

[0058] Embodiment 2: This embodiment includes all the contents of embodiment 1, and provides a method for manufacturing a multi-channel MCF optical fiber connection structure based on data transmission, combined with Figures 8 to 10 shown.

[0061] The information storage submodule is used to store the optical fiber length and the compensation coefficient, and transmit them to the calculation submodule;

[0062] The power detection submodule is used to detect and obtain the optical fiber input power and transmit it to the calculation submodule;

[0066]

[0067] Among them, η is the signal attenuation index, k is the compensation coefficient, L is the optical fiber length, p out is the index of the optical fiber output power, p in is the fiber input power.

[0068] When calculating the submodule, refer to the following program code:

[0069]

[0070] Specifically, the smaller the value of the signal attenuation index is, the smaller the signal loss is during the transmission process; the unit of the optical fiber length is centimeters; the unit of the optical fiber output power is watts.

[0071] Regarding the "compensation coefficient", the following corresponding values ​​are obtained through experiments. When the optical fiber is a standard single-mode optical fiber, the corresponding compensation coefficient is 0.4 when the corresponding wavelength is 1260nm, the corresponding compensation coefficient is 0.35 when the corresponding wavelength is 1310nm, the corresponding compensation coefficient is 0.2 when the corresponding wavelength is 1550nm, and the corresponding compensation coefficient is 0.25 when the corresponding wavelength is 1625nm; when the optical fiber is a non-zero dispersion-shifted single-mode optical fiber, the corresponding compensation coefficient is 0.19 when the corresponding wavelength is 1550nm; when the optical fiber is a multi-mode optical fiber, the corresponding compensation coefficient is 3 when the corresponding wavelength is 850nm, and the corresponding compensation coefficient is 0.8 when the corresponding wavelength is 1300nm; this embodiment only analyzes the optical fibers given as examples above.
