0-25dB Single-Channel Mini MEMS VOA with WDL and PDL Control

The FT-3955 from F-tone Networks is a single-channel mini MEMS variable optical attenuator with controlled wavelength dependent loss and polarization dependent loss for demanding optical network builds. Its electrostatic MEMS mirror steers the input beam onto the output fiber, with drive voltage setting the tilt angle and the exact attenuation level from 0 to 25 dB. Operating wavelength spans 1260 to 1620 nm with a 5 V drive voltage. Maximum insertion loss is 0.7 dB, return loss stays above 45 dB and repeatability is within 0.1 dB. Broadband wavelength dependent loss is held within 0.2 dB. The hermetically sealed package measures 16 x Phi5.4 mm and operates from -5 to 70 degrees C.
