SKU: MOAP

The mini MEMS Variable Optical Attenuator Integrated with Input Optical Power Monitor is a hybrid fiber optical device that integrates a thin-film tap of flat spectral response and a high sensitivity PIN photodiode for power monitoring applications with a MEMS VOA. The Power Monitor minimizes component assembly costs and module footprint. The thermal MEMS VOA has little temperature dependence and drift. It is intrinsically more reliable than electrostatic MEMS VOAs.

The Power Monitor has low insertion loss and low dark current with high temperature stability over a wide wavelength range from 1260nm to 1620nm band.

Notes:

  1. Without connector and in room temperature. If the tap ratio higher than 3%, the insertion loss will increase.
  2. At attenuation equal or less than 20dB
  3. At 0dB attenuation and in whole temperature range
  4. Within 30nm Bandwidth
