Variable in-line optical attenuators,also know as adjustable
in-line optical attenuator or short as VOA, are used to permit dynamic
control of optical power levels in a fiber. It can be applied to
adjust power level of signal in the optical communication at the output of light
sources, E/O converters and for the linear or dynamic range of power meter.
Furthermore, they can the used in optical amplifier systems to balance the gain
across the different operating wavelengths.
