[0042] This embodiment solves the problem that the traditional connection structure cannot meet the connection requirements. Through the multi-channel design of the communication slots 120 and the communication holes 320, the requirement for high-density connection is solved.

[0043] This embodiment also provides a manufacturing method for a multi-channel MCF optical fiber connection structure based on data transmission, which is applied to the multi-channel MCF optical fiber connection structure based on data transmission and includes the following steps: Step S1: Design the optical fiber arrangement, connector 300 structure, and optical bridge 100 structure according to the requirements of data transmission; Step S2: Cut, polish, and grind the end faces of the optical fibers, and butt the optical fibers and the connector 300; Step S3: Assemble the optical fibers and the connector 300; Step S4: Detect the assembled optical fibers and the connector 300.

[0044] Optionally, in Step S4, the detection module includes a visual detection sub-module, a flatness detection sub-module, an information setting sub-module, a control sub-module, an alignment judgment sub-module, and a communication sub-module; the visual detection sub-module is used to detect and obtain the x coordinate of the center point of each fiber end face, the x coordinate of the highest point of each fiber end face, and the x coordinate of the lowest point of each fiber end face, and transmit them to the control sub-module; the flatness detection sub-module is used to detect and obtain the measured value of the flatness of each fiber and transmit it to the control sub-module; the information setting sub-module is used to set the total number of optical fibers, the preset distance in the x-axis direction, the error distance in the x-axis direction, and the preset value of the flatness of the optical fibers, and transmit them to the control sub-module; the control sub-module obtains the difference index of the lowest point of the fiber end face according to the total number of optical fibers, the x coordinate of the lowest point of each fiber end face, the preset distance in the x-axis direction, and the error distance in the x-axis direction, obtains the difference index of the highest point of the fiber end face according to the total number of optical fibers, the x coordinate of the highest point of each fiber end face, the preset distance in the x-axis direction, and the error distance in the x-axis direction, obtains the difference index of the center point of the fiber end face according to the total number of optical fibers, the x coordinate of the center point of each fiber end face, and the preset distance in the x-axis direction, obtains the fiber end face alignment factor according to the difference index of the center point of the fiber end face, the difference index of the highest point of the fiber end face, the difference index of the lowest point of the fiber end face, the total number of optical fibers, the preset value of the flatness of the optical fibers, and the measured value of the flatness of each fiber, and transmits the fiber end face alignment factor to the alignment judgment sub-module; the alignment judgment sub-module obtains information on whether the fiber end face alignment effect is good or bad according to the fiber end face alignment factor and transmits it to the communication module; the communication sub-module transmits the information on whether the fiber end face alignment effect is good or bad to the user terminal.

[0045] Specifically, when the alignment judgment sub-module 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 poor fiber end face alignment effect; when the fiber end face alignment factor is less than the selection threshold of the fiber end face alignment factor, it indicates good fiber end face alignment effect; the selection threshold of the fiber end face alignment factor is set by those skilled in the art.

[0046] Optionally, the visual detection sub-module 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, identifies the center point, highest point, and lowest point of the fiber end face, and analyzes and obtains the x coordinate of the center point of each fiber end face, the x coordinate of the highest point of each fiber end face, and the x coordinate of the lowest point of each 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 fiber end face, the x coordinate of the highest point of each fiber end face, and the x coordinate of the lowest point of each fiber end face to the control sub-module.

[0047] Optionally, when the control sub-module calculates the fiber end face alignment factor, the following formula is satisfied:

[0048] Where AF is the fiber end face alignment factor, ΔCTR is the difference index of the center point of the fiber end face, ΔTOP is the difference index of the highest point of the fiber end face, ΔMIN is the difference index of the lowest point of the fiber end face, A is the total number of fibers, d ref is the preset value of the fiber flatness, d a is the measured value of the flatness of the a-th fiber.

[0049] Optionally, when the control sub-module calculates, the following formula is satisfied:

[0050]

[0051] Where zx a is the x coordinate of the center point of the a-th fiber end face, bz ref is the preset distance along the x-axis direction; zg a is the x coordinate of the highest point of the a-th fiber end face, wc ref is the error distance along the x-axis direction; zd a is the x coordinate of the lowest point of the a-th fiber end face.

[0052] When the control sub-module calculates the fiber end face alignment factor, the following program code is referred to:

[0053]

[0054]

[0055] Specifically, the unit of the preset distance in the x-axis direction and the error distance in the x-axis direction is millimeter. Both the preset distance in the x-axis direction and the error distance in the x-axis direction are set by those skilled in the art. "The preset distance in the x-axis direction" can be understood as the preset distance when one end of the optical fiber extends out of the end face of the corresponding component after the optical fiber is installed. The corresponding "error distance in the x-axis direction" refers to the tolerance during the machining of the optical fiber end face in 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 "the x coordinate of the lowest point of each optical fiber end face", "the highest point" and "the lowest point" refer to the "farthest point" and "nearest point" of the optical fiber end face except the center point 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 end face of the optical fiber to be tested, and specific reference can be made to Figure 1 shown). The preset value of the flatness of the optical fiber is set by those skilled in the art. The smaller the value of "flatness", the flatter it is. When the corresponding "flatness" is larger, it means the surface of the optical fiber is rougher, which will cause greater errors and impacts on the alignment measurement. The measured value of the flatness of the optical fiber can be obtained from the RMS (Root Mean Square) value calculated based on the distance from each point on the surface of the optical fiber to the reference plane and the average value of all distances.

[0056] The above unit is just an example. Those skilled in the art can 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 feedback-aligning the 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 manufacturing method for a multi-channel MCF optical fiber connection structure based on data transmission, in combination with Figures 8 to 10 shown.

[0059] For the manufacturing method of the multi-channel MCF optical fiber connection structure based on data transmission, in step S6, the quality verification module is used to verify the quality of the optical fiber and obtain the corresponding signal attenuation index.

[0060] Optionally, in step S6, the quality verification module includes an information storage sub-module, a power detection sub-module, a calculation sub-module, and a transmission sub-module;

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

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

[0063] The calculation sub-module obtains the index of the optical fiber output power based on the optical fiber input power, the compensation coefficient, and the optical fiber length, obtains the signal attenuation index based on the compensation coefficient, the optical fiber length, the index of the optical fiber output power, and the optical fiber input power, and transmits the signal attenuation index to the transmission sub-module;

[0064] The transmission sub-module transmits the signal attenuation index to the user side.

[0065] Optionally, when the calculation sub-module calculates, it refers to the following formula:

[0066]

[0067] where 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, and p in is the optical fiber input power.

[0068] When the calculation sub-module calculates, it refers to the following program code:

[0069]

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

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

[0072] The above units are just examples, and those skilled in the art can set different units according to actual needs when implementing this solution.

[0073] This embodiment solves the problem of low production efficiency of traditional manufacturing methods. The cooperation between each sub-module makes the verification of the optical fiber quality fully automated from data acquisition to index calculation, reduces manual intervention, and improves production efficiency.

[0074] The content disclosed above is only a preferred and feasible embodiment of the present invention, and does not limit the protection scope of the present invention. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the protection scope of the present invention. In addition, with the development of technology, the elements therein can be updated.
