The optical power regulator is a module that maintains a constant output power, regardless of the input fluctuations. This is achieved by using a detector to tap a small amount of light from the output and feed it into a closed-loop circuit to control a MEMS variable fiber optical attenuator connected between the light input and output. The regulation output power range is set by the two pots on the board and can be preset according to customer specs. The module can also compensate for slow polarization-dependent loss changes and fast optical power surges. The optical power regulator provides the ultimate solution for optical power stabilizing and limiting. The device is designed for over 20 years of continuous operation.  The unit comes with a wall-plug 12V power supply.
