Polarization Maintaining MEMS VOA

  • Wavelength: or Custom Wavelength 1550nm
  • Handling Power: 300mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 1550 nm Polarization Maintaining MEMS Optical Fiber Attenuator (PM MEMS VOA)  utilizes advanced Micro-Electro-Mechanical System (MEMS) technology to achieve desired optical attenuation. It's based on a PM MEMS chip, which consists of an movable mirror on a silicon.  A voltage applied to the PM MEMS chip makes the mirror to rotate, which alters the coupling efficiency of light passing through the PM MEMS VOA. It can be configured as bright or dark devices
