ABSTRACT:
Glass optical fiber having a primary coating constructed from two layers (having a total thickness 50-70 .mu.m), in which the first layer on the fiber consists of UV cured acrylate resin having a modulus of elasticity at 25.degree. C. less than or equal to 5 N/mm.sup.2. The second layer is also a UV cured acrylate resin, but has a modulus of elasticity at 25.degree. C. of from 25 to 1500 N/mm.sup.2. The ratio of the thickness of the first layer to the thickness of the second layer is between 0.5 and 2.
