Polarization Maintaining (PM) Inline Fixed Attenuators

   Gould's polarization maintaining (PM) Inline Fixed Attenuators are passive, all-fiber wavelength flattenecomponents with fixed preciselycontrolled attenuation. These components offer very low back reflection, and highpolarization extinction ratio.
Polarization Maintaining Fiber Optic Attenuators Features
  • High Polarization Extinction Ratio
  • Many Wavelength bands from UV-2100
  • Custom & Standard Attenuation Levels
  • Excellent Precision
  • Low Back Reflection (≤-60dB)

 

Applications
  • Optical Power Attenuation
  • Sensors & Fiber
  • Gyroscopes
  • Test and Measurement
  • Telecom
