Variable Optical Attenuator
Gloriole’s Variable Optical Attenuator (VOA) can be applied to adjust the power levels of signals in optical communications at the output of light sources, E/O converters and for testing the linearity or dynamic range of optical power meters.
Gloriole’s Variable Optical Attenuator (VOA) can also be used in optical amplifier systems to balance the gain across the different operating wavelengths.
