摘要： A process for manufacturing an optical fiber (200), the process comprising: drawing an optical waveguide (205) from a glass preform (105); applying (135) a layer of a first coating material on the optical waveguide; curing the first coating layer material to obtain a first coating layer (210); applying (150) a layer of a second coating material onto the first coating layer; applying (165) a layer of colored coating material (220) onto the second coating layer; curing the second coating material and the colored coating material in a single step, to obtain a second coating layer (215) superposed on the first coating layer and a colored coating layer (220) superposed on the second coating material layer, the obtained second coating layer having an elastic modulus higher than that of the first coating layer and lower than that of the colored coating layer. An optical fiber and an apparatus for producing it are also provided.
