    • MINI Manual Variable Attenuator     


    Mini Type Manual variable Attenuator (MVOA) operates by manuallymoving a shading element into optical beam. The shading element can be integrating adjusted to get any attenuation value in a range.MVOA features low insertion loss, good resolution, high stability and good reliability. It is applied for pre-emphasis attenuation, transmitter power control, in-line power equalization, and amplifier power control.
