Claim 8:
9. An optical fiber ribbon comprising:
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 optical fiber cores,
wherein a coupled section and a separate section are formed to be arranged in the longitudinal direction, the coupled section being in a state in which the optical fiber cores are coupled by the coupling member, the separate section being in a state in which at least two of the optical fiber cores adjacent to each other are not coupled by the coupling member,
wherein the plurality of optical fiber cores are divided into three or more groups each including at least two optical fiber cores,
wherein, in the three or more groups, the optical fiber cores adjacent to each other are coupled to each other in a state of being in contact with each other,
wherein, in the coupled section, adjacent groups of the three or more groups are coupled to each other,
wherein, in the separate section, adjacent groups of the three or more groups are not coupled to each other, and
wherein at least one group of the three or more groups has four or more cores.
