This series of Lithium Niobate fiberoptic Modulators is designed for laboratory test use. Its low operating voltage makes it convenient to use a function generator as the driver. It has a bias control section that integrates with a tap monitor for stable operation. The modulator is mounted on a PCB in which the bias can be applied through a SMA connector. Automatic bias control option is also available that maintain the Vp via a slow speed feedback circuitry.
