Variable Optical Attenuator VOA ST 0-60dB

Variable Optical Attenuator VOA ST 0-60dB

Variable optical attenuators,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.

Variable Optical Attenuator VOA ST 0-60dB


SZOPT’s variable optical attenuator has the function that attenuation can be adjusted as request,which is much different to the fixed optical attenuator.There are two types of optical variable attenuators—these are known as the stepwise variable attenuator and the continuously variable attenuator. Please reach us for details.


Application:

-Fiber optical distributing frame
-Fiber optical network system
-High speed fiber optical transmission system
