摘要
The attenuator for optical fibers with attenuating fiber according to the present invention comprises an optical fiber having a profile of reflective index with partially depressed cladding, of a length equal to the one of the whole attenuator, drugged with chemical substances like ions of transition metals and elements of rare earth, for creating a uniform spectral attenuation in the field of wavelengths between 1260 nm to 1650 nm.
