Abstract
A optical fiber includes an optically transmissive element; at least one curable colored layer surrounding the optically transmissive element; and an additional removable colored layer surrounding and homogeneously covering the curable colored layer. The presence of the additional removable colored layer improves identifiability of the fiber, especially when the latter is included in an optical cable together with other fibers.
