Overview

It is well known that the inherent drift of Mach-Zehnder modulators is caused by aging and environmental variations. Thus, when the modulator is used for optical pulse generation (Min bias point operation), the modulator drift causes a radical optical pulse extinction ratio loss.
iXblue MBC-DG-LAB Modulator Bias Controllers (MBC) is designed to compensate the drift and maintain with an exceptional accuracy the modulator bias point to reach a very high optical pulse contrast value and stability.
The MBC-DG-LAB is an automatic bias controller specially designed to lock the operating point of LiNb03 Mach-Zehnder modulators and ensure a stable operation over time and environmental conditions.
The MBC-LAB benefits of an Auto-set operation for the Min modes resulting in a simplified use.
