1310m polarization-maintaining acousto-optic modulator (operating frequency 200MHz)

Idealphotonics' acousto-optic modulators are widely used in the field of fiber optic sensing due to their high modulation extinction ratio and high power handling. This product is specially developed for the application needs of fiber optic sensing, with the advantages of small size, low power consumption (<1W), fast rise time (12ns), good modulation pulse shape (small overshoot), good pulse repeatability (small repetition period jitter), etc., and 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.

Product features：Small size、 Low power consumption (<500mW)、 Fast rise time (12ns)、 Good modulated pulse shape (small overshoot)、 Good pulse repeatability (small repetition period jitter)

Application area：Fiber optic sensing、 LiDAR、 BOTDA
