Mini Type Manual variable Attenuator (MVOA) operates by manually moving a shading element into optical beam. The shading elementcan 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.
Note:Package type P1&P3 is designed for 250um or 900um fiber jacket – Package type P2&P4 is designed for 2mm or 3mm fiber jacket.Mini Manual VOA
