ABSTRACT:
A coated optical fiber of the invention is constructed by coating an energy beam curable resin onto the outer periphery of a wiredrawn optical fiber and curing the resin by radiating an energy beam to the resin to thereby provide a coating layer on the optical fiber. The temperature of peak mechanical loss tangent, Tan .delta., of the energy beam curable resin prior to curing is 25.degree. C. or lower.
