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.

Adapter type fixed attenuator is the female to female fixed fiber optic attenuator,whichutilizes the air gap between two connectors to achieve the optical attenuation. Fixed adapter type attenuator is simple, low-cost and compact. It is recommended for use where return loss is not a concern nor is absolute attenuation value.
