0-40dB Single-Channel Micro MEMS Variable Optical Attenuator with Low WDL and PDL

The FT-3951 is a single-channel variable optical attenuator based on electrostatic MEMS technology, integrating a movable micromirror on a silicon chip. Incoming light is reflected by the mirror and coupled onto the output fiber, while the applied drive voltage adjusts the mirror tilt to set the desired attenuation anywhere from 0 to 40 dB. Housed in a miniature hermetically sealed TO46 package, the FT-3951 delivers low insertion loss, low polarization dependent loss and high attenuation accuracy across a broad wavelength range. Its low 6.5 V drive voltage and fast 5 ms response make it well suited for dynamically configurable optical networks.
