    The PZTx-LSM phase modulator is a phase modulation device composed of optical fiber wound on piezoelectric ceramic (PZT) and using the PZT piezoelectric effect. It adopts a unique multi-layer winding method, which makes the product have high stability and high-speed modulation characteristics. It can be equipped with a variety of types of optical fibers (see ordering information) and can be applied to open-loop phase modulation and demodulation, variable optical fiber delay line, optical fiber interferometer, & OTDR, optical fiber vibration calibration and other optical sensing fields. The module is compact and small, which is convenient for customers to integrate the system. Low voltage driving capability, suitable for standard signal source driving capability.
