Abstract
An optical conductor comprises a fiber, in particular a glass fiber, surrounded by a protective polymer material of the UV-curable type. The protective polymer material contains a water-absorbing additive, preferably a carbodiimide, a poly-carbodiimide, or a polyurea. When the additive is based on carbodiimide, it opposes photodegradation.
