The mechanical variable fiber attenuator provided by YINGDA is an optical passive device that can actively adjust the attenuation amount of optical signal power according to demand. Unlike fixed attenuators that can only provide a constant attenuation value, the core value of MVOA lies in its “adjustability” – the ability to continuously or stepwise adjust the attenuation amount in the range of 0dB to 60dB. It is widely used in 5G base station, data centers, fiber optic testing systems, and LiDAR, it is a key passive component for optimizing communication links and protecting sensitive detectors.
