Product Description


This handheld optical variable attenuator is used with single-mode fiber for continuously variable optical signal attenuation. Featuring a rugged design, portability and ease-of-use, the attenuator is widely used in fiber link certification, routine maintenance and in lab environments. The attenuator can be used in digital system communication devices such as PHD and SDH and also in analog modulation CATV systems. Other common applications for the attenuator include telecom maintenance, CATV maintenance, comprehensive cable construction systems, optical instruments research and development and optical communication training.

Key Features

  • Stepwise attenuation; 0.05 dB steps
  • On line attenuation
  • Displays absolute and relative attenuation value
  • Optical auto-off function deactivates after 10 minutes of idle time
  • Combines the functions of both an attenuator and an optical power meter
  • Wavelength, input power, output power, current attenuation and selected step size can be displayed simultaneously on LCD
  • Memorizes the attenuating value and step on shut down and restores the values on next power up
  • Low battery power indication
  • Portable, rugged, lightweight and easy to use
