摘要： Provided is an method of manufacturing an optical fiber tape core wire with which, even when the optical fiber tape core wire is separated into optical fiber wires, it can be determined which optical fiber tape core wire each optical fiber wire is associated with. A fiber running length adjustment device 13 adjusting the running lengths of the optical fiber wires 2 running from printers 8 (8A to 8D) to a tape forming device 11 is used to adjust the running lengths of all the optical fiber wires 2 between the printers 8 and the tape forming device 11 to a same length. By this adjustment, markings 6 formed on each optical fiber wire 2 (2A to 2D) can be aligned with the corresponding markings 6 formed on the other fiber wires 2 to the same position.

摘要： [Technical Problem] To inspect an intermittent connection type optical fiber ribbon with high accuracy even when the number of optical fibers of the intermittent connection type optical fiber ribbon increases. [Solution to Problem] A method for inspecting an intermittent connection type optical fiber ribbon includes: accumulating one-dimensional images in a width direction of an intermittent connection type optical fiber ribbon arranged intermittently with connection parts that connect adjacent optical fibers, by repeating capturing an image of an intermittent connection type optical fiber ribbon along the width direction, while making the intermittent connection type optical fiber ribbon move in a longitudinal direction; and creating a two-dimensional image of the optical fiber ribbon by aligning a plurality of the one-dimensional images that have been accumulated in a second direction orthogonal to a first direction in which pixels configuring the one-dimensional image are aligned.

摘要： [Problem] To achieve, at low cost, identification of optical fibers constituting an optical fiber ribbon.
[Solution] The disclosure involves an optical fiber ribbon including a plurality of optical fibers arranged side by side in the width direction. Each optical fiber includes a colored section colored by an identification color for identifying the optical fiber from the other optical fibers. The respective colored sections of the plurality of optical fibers are each formed by coloring a portion, in the length direction, of the respective optical fiber according to a common pattern.
