Description
PlugTech Precision Systems’ modulator bias controller is specially designed for Mach-Zehnder modulators to ensure stable operations in various operating environments. Based on its fully digitized signal processing method, the controller can provide ultra stable performance.
The controller injects a low frequency, low amplitude dither signal together with a bias voltage into the modulator. It keeps reading the output from the modulator and determines the condition of the bias voltage and the related error. A compensate bias voltage will be applied afterwards according to the previous measurements. In this way, the modulator is ensured to work under a proper bias voltage.
The controller is very compact in volume, and is suitable for modern communication systems.
