The Precision High Speed Optical Attenuator maintains a constant attenuation, regardless of the environment fluctuations. The attenuation level can be varied at a fast speed.  This is achieved by integrating  two tap detectors at the fiber input and output of a NanoSpeedTM attenuator, and controlling the ratio using a feedback close-loop circuit. The attenuation is proportional to the 0-5V control signal. The module can also compensate slow polarization dependent loss changes and fast optical power surges.  The non-mechanical device has passed the most stringent mil-spec and space flight qualifications, and is designed for over 20 years continuous operation.  The module comes with a wall-plug 12V power supply.
