Rof Electro-optic modulator 1550nm AM Series High Extinction Ratio Intensity Modulator

Short Description:

ROF-AM-HER series high extinction ratio of electro-optic modulator based on M – Z push-pull structure intensity, has a lower half wave voltage and stable physical and chemical characteristics, using special technology to ensure the device with high extinction ratio of DC, and the device has high response speed, and therefore is widely used in light pulse generator, optical fiber sensing, laser radar, and other fields.
