Abstract: An optical fiber ribbon is intermittently connected in a length direction by an intermittent connection which includes a polyol having a weight-average molecular weight of 3000 to 4000 in a specific amount relative to the entire intermittent connection and which has Young's modulus at 23° C. within a specific range. When collectively unitizing optical fiber ribbons to form an optical fiber cable, an optical fiber ribbon is formed which maintains advantages of the optical fiber ribbon and which prevents cracks of the intermittent connection and detachment of the intermittent connection from a colored optical fiber core when the cable is subjected to repetitive ironing.

Abstract: An optical fiber ribbon according to the present invention includes a collective coating layer containing an ultraviolet curable resin containing amorphous PPG and an amorphous monomer, the collective coating layer formed around coated optical fibers. The collective coating layer has an equilibrium elastic modulus of 12 MPa to 20 MPa, both inclusive, and a yield point elongation of 5% to 9%, both inclusive, and the adhesion between the collective coating layer and the outermost layers of the coated optical fibers is 12 N/cm to 15 N/cm, both inclusive.
