A method of splicing multicore optical fibers to one another for use in a data network. First and second multicore optical fibers each have a number of cores arranged in a certain pattern about the fiber axis, thus defining a number of pairs of cores wherein the cores of each pair are arrayed symmetrically with respect to a key plane that includes the fiber axis. Ends of the first and the second fibers are arranged in axial alignment to one another such that the key plane at the end of the first fiber is aligned with the key plane at the end of the second fiber, thereby placing a defined pair of cores in the first fiber in position for splicing to a corresponding defined pair of cores in the second fiber. The defined pairs of cores in the two fibers are then spliced to one another.

Brightness profile data having a number of dimensions is extracted based on image data in a radial direction of an optical fiber, the brightness profile data representing features for each rotation angle of the optical fiber. Machine learning uses training data to create a prediction model that based on the brightness profile data determines a rotation angle of each pair of optical fibers is. The pair of optical fibers are rotated to the determined rotation angle and then fusion spliced. The training data indicates a correspondence relationship between the rotation angle of the optical fiber and brightness profile in the radial direction for each rotation angle of the optical fiber. The prediction model can determine a rotation angle of an arbitrary optical fiber based on brightness profile data of the arbitrary optical fiber.

The splicing structure includes: a splicing adjustment component, a splicing alignment component, and a splicing base. The splicing adjustment component and the splicing alignment component are connected to the splicing base; and the splicing adjustment component is configured to support at least two to-be-spliced pieces; the splicing alignment component is configured to align the at least two to-be-spliced pieces to a first reference site. The splicing adjustment component is further configured to drive at least one of two adjacent to-be-spliced pieces in the at least two to-be-spliced pieces to move relative to the first reference site, to enable the two adjacent to-be-spliced pieces to be close to or far away from each other.

The fusion splicer includes a first holding unit, a second holding unit, a screen, a first measurement device, a first driving unit, a second driving unit, and a third driving unit. The screen has a light guide portion through which only test light emitted from one of the plurality of cores of the first optical fiber can pass. The screen is disposed between the end face of the first optical fiber and the end face of the second optical fiber. The first measurement device measures the intensity of leakage light leaking from the second optical fiber. The third driving unit adjusts the position of the screen such that the light guide portion is aligned with one of the plurality of cores of the first optical fiber in the axial direction of the first optical fiber.
