Optical fiber ribbon and optical fiber cable housing optical fiber ribbon

A batch of optical fiber cables including at least 100 optical fiber cables, each optical fiber cable comprising:

• an optical fiber ribbon comprising:
• three or more optical fibers arranged in parallel, wherein a gap is defined between each adjacent two optical fibers of the three or more optical fibers, wherein each of the three or more optical fibers has an outer diameter of less than or equal to 220 microns, and wherein a distance along the width direction between centers of the adjacent two optical fibers is 250 microns with a margin of plus or minus 30 microns;
• connecting portions filling resin into the gap between each adjacent two optical fibers and intermittently connecting the adjacent two optical fibers both in length and width directions of the adjacent two optical fibers;
• wherein at least one of the connecting portions has at least one outer surface which is positioned on a line connecting contact points of the adjacent two optical fibers when placed on a horizontal surface.
