Rof Electro-optic modulator 1550nm Phase Modulator 2.5G linbo3 modulator

Short Description:

The LiNbO3 phase modulator (linbo3 modulator)is widely used in high-speed optical communication system, laser sensing and ROF systems because of well electro-optic effect. The R-PM series based on Ti-diffused and APE technology, has stable physical and chemical characteristics, which can meet requirement of the most applications in laboratory experiments and industrial systems.
