Abstract
The present invention relates to a method of manufacturing a cable containing optical fibers, the cable including an optical core assembly surrounded by a plurality of mechanical reinforcing members made of a plastics material reinforced with reinforcing fibers, referred to as an "FRP" material, the reinforcing members being disposed helically around said core assembly so as to form a reinforcing tube, said reinforcing members having a thermal expansion coefficient that is lower than those of the remaining portions of said cable and a Young's modulus that is higher than those of the remaining portions of said cable other than said optical fibers. The method includes the following steps: simultaneously manufacturing said reinforcing members on their own and by coating said reinforcing fibers with the plastics material, without the material being polymerized; winding said reinforcing members around said optical core assembly, while interposing a separator made of a plastics material having low adhesion to said FRP material between each of said reinforcing members, so as to separate them; and polymerizing said plastics material.
