variable optical attenuator is an online attenuation amount adjustment device. It is applied to the situation of optical power required strict control in network, which the most common is cooperate in DWDM network.
It adopts MEMS technology and could continually and variably attenuate the light intensity in the optical fiber transmission and could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link.
