Variable Optical Attenuator (VOA) operates by manually moving a shading element into optical beam. The shading element can be integrating adjusted to get any attenuation value in a range. Our VOA features low insertion loss, good resolution, high stability and good reliability. It applies for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control, etc. A smaller version is available, the Mini Type VOA, even more compact.
Fixed Optical Attenuator
