Abstract: An optical fiber includes a primary covering layer, a secondary covering layer transparent to a laser beam, an intermediate covering layer less than 100 nm thick between the primary covering layer and the secondary covering layer and including a coloring element whose coloring properties can be modified by using the laser beam to irradiate the intermediate covering layer to write data.
