Inline Variable Optical Attenuator

The RUR in-line variable optical attenuator (VOA) is used for precisely balancing the signal strengths in fibre circuits, or balancing an optical signal when evaluating the dynamic range of the measurement system.


  • Compact size, Low insertion loss
  • Wide attenuation range
  • High precision and stable attenuation
  • Optical communication systems test
  • Fibre component test
  • Optics lab use
