Abstract
An optical fiber ribbon includes a plurality of optical fiber cores arranged in parallel in a direction orthogonal to a longitudinal direction of the optical fiber cores, and a coupling member configured to couple the plurality of optical fiber cores. In the optical fiber ribbon, a plurality of coupled sections and a plurality of separate sections are alternately provided in the longitudinal direction. Each of the plurality of coupled sections is in a state in which all of the adjacent optical fiber cores are coupled by the coupling member. Each of the plurality of separate sections is in a state in which at least two of the optical fiber cores adjacent to each other are not coupled by the coupling member.
