Abstract
An optical fiber includes an optical transmission medium having a core and a cladding, a primary resin layer disposed in contact with the optical transmission medium to coat the optical transmission medium, and a secondary resin layer coating the primary resin layer, wherein a Young's modulus of the primary resin layer is 0.5 MPa or less at 23° C., and the primary resin layer comprises a cured product of an ultraviolet light curable resin composition containing a urethane (meth)acrylate oligomer, a monomer, a photopolymerization initiator and a β-diketone compound, and tin.
