Yin-Yang fixed attenuator is a kind of attenuator whose one end is connector type and the other end is adapter type (called Yin-Yang type) and the attenuation value is not adjustable. The Yin-Yang fixed attenuator is mainly used to attenuate the optical power in the optical link, so as to obtain the desired target optical power value. The attenuation value has great selectivity. It can be selected from 0 to 30 dB. It can be applied to the wavelength range of 1250 to 1650 nm.
