首页 Optical Accessories Active devices AOM 1550/1650nm single-mode/polarization maintaining fiber acousto-optic modulator 1550nm polarization-preserving acousto-optic modulator 40MHz

    • 1550nm polarization-preserving acousto-optic modulator 40MHz

    Acousto-optic modulators are widely used in the field of fiber optic sensing due to their advantages such as high modulation extinction ratio and high power handling. This product is specially developed for the application requirements of fiber optic sensing, and has the advantages of small size, low power consumption (<1W), fast rise time (12ns), good modulation pulse shape (small overshoot), good pulse repeatability (small repetition cycle jitter), etc. In addition, the modulator and driver can be packaged in an integrated manner, which is convenient for system integration. It can be widely used in various fiber optic sensing systems that require pulse modulation, such as φ-OTDR, BOTDR, OFDR, etc.

    产品特点Small size 、 Low power consumption (<500mW) 、 Fast rise time (12ns) 、 Good modulation pulse shape (small overshoot) 、 Good pulse repeatability (small jitter in repetition period)
