Modulator bias controllers are used to lock the operating point of Mach-Zehnder modulators. They are necessary to compensate for the drift caused by aging and changes in environmental conditions. Unlike classical dither signal based bias controllers, the MBC-AN-series do not superimpose any tone signal to the optical modulated signal. They are designed to lock the operating point of modulators for applications where such a tone signal is not desired and typically for analogue applications such as RFoF, remote antenna and radar links.
MBC-AN controllers are compatible with all Photline Technologies analogue modulators, and they are the latest addition to the our product range.
