Optical fiber ribbon and optical fiber cable

An optical fiber cable implementing an optical fiber ribbon, the optical fiber ribbon comprising:

• a plurality of optical fiber cores arranged in parallel spaced from each other;
• and
• a tape forming member having coating portions covering each outer circumference of the optical fiber cores, spaced each other, and a coupling portion, integrally formed with the coating portion, intermittently coupling the coating portions each covering adjacent optical fiber cores,
• wherein each thickness of the coupling portions is less than each thickness of the optical fiber cores including the coating portions, and
• each of the coating portions has an opening portion to expose a part of a surface of only a respective one of the optical fiber cores, and at least a part of the coating portion is continuous in a longitudinal direction of the optical fiber cores.
