We can provide with the driver for the above electro-modulators and integrate the modulator, amplifier and relevant controllers together. The user can manually or automatically set the bias points. At the manual setting mode, the bias can be displayed and the EO modulator and amplifier individually operate. At the automatic setting mode, the user can set various bias points according to the demand and the bias point is locked and displayed. The modulation performance of the modulator is not influenced by external factors such as environment temperature and vibration.
