Electrical and Digital Driven Attenuators

Digital Variable Attenuators

Key Features

  • CE Compliant
  • High power handling (up to 2 watts)
  • High speed
  • Wide attenuation range
  • Low PDL and wavelength dependency
  • Low insertion loss and backreflection
  • High resolution
  • Rugged and compact design


OZ Optics offers a compact, rugged and low cost digital attenuator with high resolution, high speed, high attenuation range and high power handling (blocking technique only). OZ Optics' digital attenuator is a hand held unit, CE approved. These attenuators have low insertion loss, low backreflection, low PDL and flat wavelength response. These units can be calibrated for up to 4 wavelengths, for C or L bands.

Alternatively the unit can be calibrated for a continuous range. By using interpolation between the calibration wavelengths, the unit is capable of providing accurate attenuation levels over a continuous, broad range of wavelengths.
