The fixed or variable optical attenuator of the type of attenuation plate directly fixes the attenuation plate with absorption characteristics on the end face of the optical fiber or in the optical path to achieve the purpose of attenuating the optical signal. This method can not only be used to make fixed optical attenuators but also to make variable optical attenuators. The optical attenuation plate protects the eyes ...
