ABSTRACT:
A laser-markable cable, in particular an optical fiber cable, having an outer protective layer of varnish comprising an outer layer (14) provided with a pigment and sublimable by means of a first type of laser, and an inner underlayer (13) of a contrasting color relative to that of the outer layer. The cable is characterized by the fact that said outer layer (14) is also modifiable in color by a second type of laser without being destroyed in thickness, thereby providing a second possible method of marking.
