Optical fiber ribbon with intermittently coupled groups of fibers

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 plurality of optical fiber cores,
• wherein a plurality of coupled sections and a plurality of separate sections are alternately provided in the longitudinal direction, one of the plurality of the coupled sections being in a state in which all adjacent optical fiber cores of the plurality of optical fiber cores are coupled by the coupling member, one of the plurality of separate sections 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 sections, adjacent groups of the three or more groups are coupled to each other,
• wherein, in the separate sections, 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.
