Variable Optical Attenuator VOA FC 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.

Feature:
-High return loss
-Simple structure
-Max operation power(1W)
-Low wavelength relativity
-Low polarization related loss
Package:
Each in a PE bag,finally put in a carton box.
