ABSTRACT:
This method allows manufacture of an optical cable including optical fibers (1) placed in a protective sheath including two coaxial tubes (3, 5), of which the inner tube (3) which is made of plastic material, contains said fiber (1). The method consists in placing the fibers in the first tube (3) so that they have a certain overlength with respect to said tube. Then, the assembly (1, 2, 3) is surrounded by second tube (5). The second tube (5) is placed around the first tube (1) after obtaining the overlength, from a metal tape whose longitudinal edges are butted together progressive around the assembly while being fixed to each other, then the second tube (5) is shrunk against the first tube (3). A layer adhesive material (4) is preferably interposed between the two tubes (3, 5).
