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 the primary resin layer comprises a cured product of an ultraviolet light curable resin composition comprising a urethane (meth)acrylate oligomer, a monomer and a photopolymerization initiator, and a compound containing phosphorus and tin as constituent atoms; and a Young's modulus of the primary resin layer is 0.5 MPa or less at 23° C.
