    Rof Bias Point Controller automatic bias control module of lithium niobate MZ modulator

    ROF-ABC-MZ series automatic bias control module is used for automatic bias control of lithium niobate M-Z modulator, which can make the modulator work stably at the lowest point, the highest point or the orthogonal point (linear region). The module is also integrated with 1/99 coupler, which can control the switching of the working point through the external serial port, and supports manual adjustment mode, which is suitable for a variety of different wavelength modulators and applications, and is very suitable for university laboratories to build desktop experiments.

    Ultra Compact DP-IQ Modulator Bias Controller Automatic Bias Controller

    Rofea’ modulator bias controller is specially designed for Mach- Zehnder modulators to ensure a stable operation state 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 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 new bias voltage will be applied afterwords according to the previous measurement. In this way, the modulator is ensured to work under proper bias voltage.
