High Speed Precision Variable Optical Attenuator No Drift

SKU: PNSA

The Precision High Speed Optical Attenuator maintains a constant attenuation, regardless of environmental 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 closed-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 of continuous operation. The module comes with a wall-plug 12V power supply.
