Boston Applied Technologies' Micro Variable Optical Attenuator (µVOA) is a voltage controlled optical variable attenuator. Based on the patented proprietary OptoCeramic® technology platform, the Eclipse™ VOA provides high speed, high dynamic range, low insertion loss, low polarization dependence loss and the best reliability in a very compact package. The devices also enable polarization independent modulation of an optical signal traveling over standard single mode fiber while simultaneously maintaining a specified level of attenuation.
