Variable Optical Attenuator C + L Band

  • Wavelength: 1550nm C+L Band
  • Handling Power: 500mW
  • Fiber Type: Single Mode Fiber
Product Details

The C + L Band Mechanical Variable Optical Fiber Attenuator (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.
