Abstract
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.
