Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed 5dB loss
They are used to control the power level of optical signals at the outputs of light sources and electrical to optical (E/O) converters
They are also used to test the linearity and dynamic range of photo sensors and photo detectors
