    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： To achieve early detection of abnormalities occurring during manufacturing of an intermittently-connected optical fiber ribbon, an intermittently-connected optical fiber ribbon manufacturing method of the present disclosure includes: (1) intermittently forming, with a connecting device, connection parts between optical fibers; (2) measuring a load of the connecting device when intermittently forming the connection parts; and (3) detecting an abnormality based on the load.
