1310/1480/1550nm Mini Type MVOA (O-L band)

low insertion loss, good resolution, high stability and good reliability
  • Product Detail

Mini Type Manual variable Attenuator (MVOA) 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. MVOA 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.
