Abstract
A method for manufacturing an intermittently coupled-type optical fiber ribbon includes arranging a plurality of optical fibers in parallel in a direction orthogonal to a longitudinal direction of the plurality of optical fibers, coating all of the plurality of optical fibers with a coupling resin, intermittently inserting a cleaving blade into the coupling resin between some adjacent optical fibers of the plurality of optical fibers to form slits. An outer diameter of each of the optical fibers is 220 μm or less. A distance between the optical fibers into which the cleaving blade is inserted among the adjacent optical fibers is 10 μm or more and 100 μm or less.
