摘要

Problem to be solved: to adjust the circumferential rotational position of a plurality of multicore fibers by a simple method.Solution: sending a multicore fiber having a plurality of cores and a magnetic body disposed at a predetermined position in the circumferential direction relative to the plurality of cores, attracting the respective magnetic bodies of the plurality of multicore fibers by magnetic force A method of manufacturing an optical fiber ribbon is formed by connecting the plurality of multicore fibers to form an optical fiber ribbon.Diagram
