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.

Un conductor óptico abarca una fibra, en detalle una fibra de cristal, rodeada por un material de polímero protector del tipo UV-curable. El material de polímero protector contiene un añadido agua-que absorbe, preferiblemente un carbodiimide, un poly-carbodiimide-carbodiimide, o un polyurea. Cuando el añadido se basa en carbodiimide, opone la fotodegradación.
