1550nm polarization-maintaining MEMS dimmable attenuator (VOA)

Ideal-Photonics' polarization-maintaining MEMS dimmable attenuator (VOA) is driven by a micro-electromechanical MEMS chip and uses electrostatic to drive the mirror to rotate to realize continuous adjustable attenuation of input light. There are two types: bright state and dark state.

Note: 

1. The above test loss (IL) is based on the test results at the center wavelength of ± 30nm and 23 ℃, requiring a multi-band increase of 0.2dB.

2. Repeatability data is based on the results of 100 cycle repeated tests.

3. No connector, including connector insertion loss increased by 0.2dB.
