Abstract
There is provided an optical attenuator for reducing back-reflection by forming the sections of optical fibers of the optical attenuator into non-spherical lenses. For this purpose, in an optical attenuator for attenuating a predetermined optical signal, the sections of first and second optical fibers spaced by a predetermined distance to face each other are formed into non-spherical lenses. Thus, optical attenuation precision is improved and impacts of back-reflection is avoided.
