    Boston Applied Technologies' EclipseTM series of Variable Optical Attenuators, including dual-function VOA/PIMs (Polarization Independent Modulators), enable all solid-state, high-speed performance in a very compact package. Depending on the specific application, the VOAs may be set to maintain an electronically adjustable value of either attenuation or output power. The PIMs enable modulation of an optical signal traveling over standard single mode fiber while simultaneously maintaining a specified level of attenuation. All VOAs are electrically controlled, and employ OptoCeramic® electro-optic technology.
