780nm Mini Polarization Maintaining Variable Optical Attenuator

  • Wavelength: 780nm or Custom Wavelength
  • Handling Power: 300mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 780 nm Mini Polarization Maintaining Variable Optical Fiber Attenuator ( Mini PM VOA) is a micro-optic component designed to control the attenuation of the optical signal passing through it, the desired attenuation can be precisely achieved by adjusting a screw. It can be used to precisely balance the signal strengths in fiber circuits, or, it can be used to balance an optical signal when evaluating the dynamic range of the measurement system.
