Fiber Optical Power Regulator

SKU: MOPR

The optical power regulator is engineered to maintain a constant output power by compensating for input fluctuations. It operates by tapping a small portion of the output light with a detector and feeding it into a precision closed-loop circuit, which controls a MEMS variable fiber optical attenuator positioned between the input and output. With a wide dynamic range, it effectively limits output against input surges of up to 40 dB. The output power level can be adjusted manually via a set screw or remotely through a USB-connected GUI. The system requires an insertion loss of approximately 2 dB to regulate the output power effectively. Additionally, it compensates for polarization-dependent loss (PDL) variations along with optical power fluctuations. This regulator provides a cost-effective solution for stabilizing and limiting optical power and is powered by a 5V wall-plug power supply included with the module.
