A method of manufacturing optical ribbons, wherein the optical fibers are paid out by an optical fiber pay-out unit, and grouped together in a nozzle where they are coated in a coating material which is caused to set in order to form an optical fiber ribbon. A plurality of groups of optical fibers are formed in parallel in as many nozzles as possible, and the groups of optical fibers, which are coated in a coating material, are caused to set simultaneously using a single setting means for setting the coating material, in order to form as many ribbons of optical fibers as possible, thereby enabling the manufacturing cost of a ribbon to be reduced.

Method of manufacturing optical fiber ribbons

A method of manufacturing a multi-ribbon optical fiber structure which contains optical fibers, and which can be separated into at least two optical fiber ribbons, said method including:

Method of manufacturing a multi-ribbon optical fiber structure that can

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 cable constituted by a single tube defining an internal bore housing at least one optical fiber and whose wall incorporates a reinforcement zone. The reinforcement zone is constituted by a thermoplastic material giving the cable both flexibility and resistance against compression and impact.
