MEMS直变光衰减器(broad wavelength, 350nm to 3000nm, all fiber types SM, MM, PM fiber)
The etMEMSTM Straight Series variable attenuator (VOA) is based on proprietary MEMS in combination with fiber-fiber technology without using lens nor any coating. It offers many industrial leading performances: exceptionally high attenuation, high power handling, and compatible with all types of fiber, as well as low cost. The device features ceramic packaging providing excellent thermal stability.
The attenuation can be continuously adjusted by directly applying a low voltage. The silicon MEMS device is highly reliable with longevity. However, it can be damaged by applying a voltage over the threshold.
