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.

Optical conductor and its method of manufacture

An optical conductor of the monomode type comprises an optical fiber covered by a primary layer surrounded by a secondary layer. To reduce the cost of fabricating the conductor, the secondary layer includes an outer part of a thermoplastics material the apparent viscosity of which at the melting point is at most approximately 100 Pascal-second at a shear rate at least equal to 100 s.sup.-1. The primary layer and the inner part of the secondary layer are made from a resin that can be cross-linked using ultraviolet radiation, for example.

Optical conductor and optical conductor ribbon cable

An optical fiber multi-ribbon including at least two initial optical fiber ribbons having individual first sheaths for assembling the fibers of each ribbon together side by side and in a common plane. The initial optical fiber ribbons are disposed side by side and in a common plane and a common exterior second sheath surrounds the initial ribbons. The individual first sheaths of the initial ribbons and the common exterior second sheath are made from the same resin. This resin is advantageously relatively hard. Applications include high-density optical telecommunication cables.
