780-1064nm Mini Type MVOA

manually moving a shading element into optical beam
  • Product Detail

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