Abstract
Disclosed are optical fibers for optical attenuation comprising a core and a cladding, wherein the cladding comprises two or more parts different from each other in their refractive indices and/or the attenuating dopant existence. By using the optical fibers for optical attenuation of the present invention, an optical attenuator which can effectively reduce the effect of cladding mode upon coupling of optical fibers and is excellent in characteristic stability can be manufactured at a low cost.
