FS card variable optical attenuator is an online attenuation amount adjustment device, which 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. It is designed for maximum configuration flexibility, with pluggable modules that plug directly into the FMT managed chassis, each module occupying one slot.
