Mini 850nm Variable Optical Attenuator

  • Wavelength: or Custom Wavelength 850nm 830nm 810nm
  • Handling Power: 300mW
  • Fiber Type: Single Mode Fiber
Product Details

  The 850 nm Mini Mechanical Variable Optical Fiber Attenuator ( Mini 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.
