An optical cable has a core containing optical fibers, non-metallic peripheral reinforcements to armor the cable and a thermoplastics material outer sheath. It is fabricated by a method including successive steps of applying reinforcements to the core, extruding the sheath over the reinforcements and cooling the cable. The reinforcements are extruded onto the core as it moves through a first extruder. The combination of the core and the reinforcements is then cooled in a first cooling tank. The sheath is extruded in a second extruder downstream of the first, after which the cable is cooled in a second cooling tank downstream of the first.
